Abstract PDF

Background

Housekeeping genes, which show constant protein expression patterns between different tissue types, are very important in molecular biological studies as an internal control for protein research.

Methods

The protein expression profiles of seven housekeeping genes (HPRT1, PPIA, GYS1, TBP, YWHAZ, GAPDH and ACTB) in various rat tissues (cerebrum, cerebellum, cardiac ventricle and atrium, psoas muscle, femoral muscle, liver, spleen, kidney, and aorta) were analyzed by Western blot and compared by coefficient of variation (CV).

Results

HPRT1 was stably expressed (CV≤10%) in six tissues (cerebrum, cerebellum, ventricle, femoral muscle, spleen, and kidney), PPIA was stably expressed in five tissues (cerebrum, cerebellum, ventricle, spleen and kidney), YWHAZ was stably expressed in three tissues (cerebrum, cerebellum, and kidney), and GAPDH was stably expressed in four tissues (cerebrum, ventricle, psoas muscle, and kidney). In comparison, GYS1, TBP, and ACTB were found to have CV values over 10% in all tissues. Of the seven genes examined, four (HPRT1, PPIA, YWHAZ, and GAPDH) were found to be stably expressed across multiple organs, with low CV values (≤10%).

Conclusions

These results will provide fundamental information regarding internal controls for protein expression studies and can be used for analysis of postmortem protein degradation patterns in forensic medicine.

Abstract PDF

Background

The incidence of early colorectal epithelial neoplasm (ECEN) is increasing, and its pathologic diagnosis is important for patient care. We investigated the incidence of ECEN and the current status of its pathologic diagnosis.

Methods

We collected datasheets from 25 institutes in Korea for the incidence of colorectal adenoma with high grade dysplasia (HGD) and low grade dysplasia in years 2005, 2007, and 2009; and early colorectal carcinoma in the year 2009. We also surveyed the diagnostic terminology of ECEN currently used by the participating pathologists.

Results

The average percentage of diagnoses of adenoma HGD was 7.0%, 5.0%, and 3.4% in years 2005, 2007, and 2009, respectively. The range of incidence rates of adenoma HGD across the participating institutes has gradually narrowed over the years 2005 to 2009. The incidence rate of early colorectal carcinoma in the year 2009 was 21.2%. The participants did not share a single criterion or terminology for the diagnosis of adenoma HGD. The majority accepted the diagnostic terms that distinguished noninvasive, mucosal confined, and submucosal invasive carcinoma.

Conclusions

Further research requirements suggested are a diagnostic consensus for the histopathologic diagnosis of ECEN; and standardization of diagnostic terminology critical for determining the disease code.

Abstract PDF

BACKGROUND
The Korean Bone and Soft Tissue Pathology Study Group of the Korean Society of Pathologists conducted a nationwide retrospective analysis of soft tissue sarcoma (STS) to provide the clinicopathologic characteristics of STS within the population of the Republic of Korea.
METHODS
The cases of STS were collected during a 7-year period (2001-2007) from 19 institutes in Korea. All cases were classified according to the histologic criteria proposed by the World Health Organization. Clinicopathologic data were reviewed.
RESULTS
Data from 722 patients (median age, 50 years) were collected. Data showed a slight male predominance. The most frequent types of STS in decreasing order were liposarcoma, malignant fibrous histiocytoma, leiomyosarcoma, and synovial sarcoma. STS occurred throughout the body, although approximately half (47.8%) were located in the extremities. The majority of STS was histologically classified as high grade with a large tumor size (>5 cm). The overall survival rate for the patients was 76.3% (median follow-up time, 26 months; range, 1 to 89 months). Histologic grade, tumor size, American Joint Committee on Cancer stage, tumor site, and resection status were prognostic. Significant independent adverse prognostic factors were large tumor size (>5 cm) and tumor site other than extremities.
CONCLUSIONS
We reported the distribution and characteristics of STS in the Republic of Korea.

Abstract PDF

BACKGROUND
The expression of the inhibitor of apoptosis proteins (IAPs) family has not been fully investigated in colorectal carcinomas. This study investigated IAP expression in colorectal carcinomas and assessed their prognostic significance.
METHODS
Livin, XIAP, and SMAC/DIABLO expression was assessed by immunohistochemistry in 159 colorectal carcinomas. Correlations between protein expression and clinicopathological features were evaluated. The survival data analysis was estimated according to the Kaplan-Meier method.
RESULTS
Increased expression of IAPs in cancer tissues compared to surrounding nonneoplastic counterparts was observed in 67 cases (42.1%) for Livin, 50 cases (31.4%) for XIAP, and 68 cases (42.8%) for SMAC. A significant correlation was found between Livin expression and tumor differentiation, and SMAC expression and tumor location. The recurrence-free and overall survival of patients with low Livin expression were inferior to those of patients with high Livin expression (p=0.054 and 0.095, respectively). High XIAP expression was significantly associated with shorter progression-free survival (p= 0.041).
CONCLUSIONS
Our study demonstrated that altered expression of IAP family members, including Livin, XIAP, and SMAC, is frequent in colorectal carcinoma. This result suggests that high Livin expression and low XIAP expression may be a favorable prognostic implication related to patient survival.

Abstract PDF: BACKGROUND
Colorectal cancer (CRC) is one of the most common malignant neoplasms and is a leading cause of mortality worldwide. Metastasis to the liver is a frequent event in patients with CRC. An essential step in the metastatic cascade is angiogenesis.
METHODS
This study included 45 patients who underwent a partial colectomy with hepatic resection for CRC with hepatic metastases. Immunohistochemistry was performed using vascular endothelial growth factor (VEGF)-A, VEGF receptor (VEGFR)-1, VEGFR-2, and CD34 antibodies to examine the relationship between CRC with liver metastases and angiogenesis.
RESULTS
CRC showed significantly stronger expression of VEGF-A, VEGFR-1, and VEGFR-2 than liver metastases (p < 0.05). Microvessel density was also higher in CRC than in liver metastases (p < 0.05).
CONCLUSIONS
Compared with previous studies, we found a higher expression of VEGF-A, VEGFR-1, VEGFR-2, and microvessel density in CRC than in liver metastases, which could be ascribed to a difference in vessel distribution and blood supply in each organ. Given its profuse blood supply and distinct cell populations, the liver might provide a rich milieu for tumor cell growth with less expression of angiogenesis-inducing agents.

Abstract PDF

BACKGROUND
pAkt (the phosphorylated form of the proto-oncogene protein c-akt) and survivin (human BIRC5 protein) are candidate apoptosis-related molecules that may be responsible for cancer progression. The aim of this study was to determine the expression of pAkt and survivin in malignant stomach neoplasm, and their value as prognostic indicators of cancer.
METHODS
The expression of pAkt and survivin in 144 cases of gastric cancer was detected by immunohistochemistry and compared with established clinicopathological parameters and prognosis of this disease.
RESULTS
Expression of pAkt showed significant correlations with depth of invasion, lymph node and distant metastasis, as well as the stage (p < 0.05 for all three correlations), but not with the Lauren classification. Survivin expression closely correlated with histological type, Lauren classification, depth of invasion, metastasis, and stage (p < 0.05 for all). The overall survival of patients with pAkt/survivin expression was inferior to that of patients with loss of pAkt/survivin expression. Cox multivariate analysis demonstrated a significant correlation between stage (p = 0.04), survivin expression (p = 0.02), and prognosis.
CONCLUSIONS
Patients with pAkt/survivin expression in gastric cancer are at increased risk of cancer-related mortality via the apoptosis resistance pathway. Expression of pAkt and survivin could be used as a prognostic indicator for gastric cancer.

Abstract PDF

BACKGROUND
DNA hypermethylation is a common epigenetic finding in human cancers and is closely associated with transcriptional silencing. In the present study, we investigated the proportion of colorectal neoplasms that showed the adenoma-carcinoma progression and vimentin gene methylation.
METHODS
Methylation status of the vimentin gene was examined in nontumoral mucosa, adenomas, and adenocarcinomas from 45 colorectal cancer patients who had adenoma and adenocarcinoma together. Methylation status was determined by bisulfite modification and the methylation-specific polymerase chain reaction. The expression of the vimentin gene product was also examined by immunohistochemistry.
RESULTS
Promoter methylation of vimentin was detected in 80% (36 out of 45 cases) of adenocarcinomas, 82.2% (37 of 45) of adenomas, and 28.9% (13 of 45) of normal epithelia, and the difference between neoplastic and normal specimens was statistically significant (p < 0.001). However, no significant correlations were observed between methylation frequency and clinicopathologic variables. Immunohistochemically, vimentin expression was not observed in either normal epithelial cells or tumor cells. Protein expression and vimentin promoter methylation were not associated.
CONCLUSIONS
The frequency of aberrant methylation of the vimentin gene was high in colonic adenomas and adenocarcinomas. This result suggests that the methylation status of vimentin may be clinically beneficial in screening for colorectal cancer patients and may be helpful in clarifying colorectal cancer biology.

Abstract PDF: The most common site for the metastasis of osteosarcoma is the lung, and other sites of metastases include the bone, lymph node, pleura and liver. Although unusual extrapulmonary metastases have been reported with the improvement of the therapeutic results for the primary lesions, they are exceptionally rare. We report here on a case of prostatic metastasis of an osteosarcoma of the proximal tibia, and this developed seven years after successful resection, and four years after resection of a pulmonary metastasis. Radical prostatectomy was performed, and histological examination demonstrated metastatic osteosarcoma. To the best of our knowledge, this is the first case of prostatic metastasis of osteosarcoma in the medical literature.

Abstract PDF

BACKGROUND
Survivin, a novel antiapoptotic gene has been linked with tumor development and progression in various human carcinomas including gastric carcinomas. The aim of this study was to evaluate the expression of survivin in gastric carcinoma and its correlation with tumor cell proliferation and apoptosis. METHODS: Expression of survivin was evaluated immunohistochemically in 84 surgically resected gastric carcinomas. Tumor cell apoptosis was evaluated with terminal deoxynucleotidyl transferase (TdT) mediated deoxyuridine triphosphate (dUTP) nick-end labeling (TUNEL), and Ki-67 immunostaining was used for evaluation of tumor cell proliferation. RESULTS: Expression of survivin was noted in 53.6% of the gastric carcinomas, and was significantly associated with depth of invasion, status of lymph node metastasis or tumor stage (p=0.022, 0.034, 0.040, respectively). There was an inverse correlation between survivin expression and apoptotic index (p=0.015). But there was no significant correlation between survivin expression and Ki-67 labeling index (p=0.430). CONCLUSIONS: These results suggest that survivin expression may contribute to tumor development and progression by inhibiting apoptosis in human gastric carcinoma.

Abstract PDF: To evaluate the differentiation status of smooth muscle in gastric stromal tumors which were negative for S-100 protein, immunohistochemistry using desmin, actin, myosin and vimentin was performed in 14 cases of gastric smooth muscle tumors. Ultrastructural Examination was also performed. For comparison a case of leiomyoma of the esophagus, a case of the sigmoid colon, 10 cases of the uterus were also examined. The results obtained were as follows. All gastric smooth muscle tumors showed vimentin-positivity. Six of 14 gastric smooth muscle tumors, (5 of 8 leiomyoma and 1 of 4 leiomyosarcoma) showed positivity for desmin, actin, and myosin(42.9%). All esophageal, colonic, and uterine leiomyomas showed diffuse positive reaction for desmin, actin, and myosin. Vimentin positivity was also noted in leiomyoma of the colon and uterus. Ultrastructurally, a few cells in the gastric stromal tumors had scattered microfilaments with dense bodies, subplasmalemmal dense plaques, and micropinocytic vesicles. However, most of the tumor cells did not have any of the ultrastructural features of smooth muscle differentiation. Leiomyomas of the esophagus and uterus showed many cytoplasmic microfilaments with dense bodies. These results suggest that most of the benign and malignant tumor cells of gastric stromal tumors have features of the undifferentiated cells, immunohistochemically as well as ultrastructurally, although a few cells have. It is speculated that most gastric stromal tumors may have lost their smooth muscle differentiation.

Abstract PDF: To evaluate the detection of HPV DNA according to subtype of lesions of uterine cervix and its clinical applicability, in situ hybridization (ISH) and immunohistochemistry for HPV were performed in 189 cases of uterine cervical lesion, including 23 cases of low grade squamous intraepithelial lesion (SIL), 115 cases of high grade SIL and 51 cases of invasive carcinoma. Positive immunostaining, brown precipitate, was mainly noted in the nucleus of koilocytes in the superficial and intermediate layer. Positivity of immunostaining was 21.7% in low grade SIL, 13.0% in high grade SIL and 9.8% in invasive carcinoma. Positive reaction in ISH, red precipitate, was noted in the nucleus of not only koilocytes but also non-koilocytes in the superficial and intermediate layer, and dot precipitate was rarely identified in the nest of squamous cell carcinoma. Based on HPV subtype, 6/11 was 21.7% in low grade SIL, 16/18 was 32.2% and 39.2% in high grade SIL and invasive carcinoma, respectively. With regard to their associated HPV types, low grade SILs were heterogeneous and high grade SILs and invasive carcinomas were related with the high oncogenic risk group only. The correlation of HPV subtypes with panHPV was 91.3% in low grade SIL, 91.3% in high grade SIL and 98.0% in invasive carcinoma. These results suggest that detection of HPV infection by ISH may be a more useful method than immunohistochemistry and application of the HPV subtype probe with the panHPV probe could improve the sensitivity of ISH.

Abstract PDF: Mutation of the p53 tumor-suppressor gene in exons 4 through 9 was examined in 34 cases of primary advanced gastric cancer using PCR-SSCP (polymerase chain reaction-single strand conformation polymorphism) and the results were compared with p53 protein expression as determined by immunohistochemistry (IHC) using a monoclonal antibody(DO-1). p53 protein detected by IHC was observed in 14 cases (41.2%) and genotypic mutation detected by PCR-SSCP in exons 4-9 was observed in 13 cases (38.2%) One case showed an aberrant band on PCR-SSCP both in Exon 7 and Exon 8/9. p53 alteration detected by either IHC or PCR-SSCP was observed in 19 cases (55.9%), but only 8 cases (23.5%) showed both p53 mutation and protein expression. We also tried to obtain the correlation between relative intensity of the shifted bands on PCR-SSCP and percentage of positive cells by IHC, but a significant correlation was not seen between relative intensity of shifted bands on PCR-SSCP and positve cell ratio. A discrepancy between p53 protein expression and p53 mutation is observed in primary gastric carcinomas. The reason for this discrepancy are not apparent. However, examination of gastric carcinomas for mutations in other exons may identify a better correlation with protein overexpression. The results obtained in this study suggest that the negative reaction for p53 immunohistochemistry may not necessarily mean no genetic alteration of the p53 locus.

Abstract PDF: To investigate the relationship between insulin response and morphometric changes of the mitochondria of pancreatic beta-cell, this study was performed using hyperglycemia and streptozotocin as oxidative stresses. Adult and neonatal rats were used. Intravenous glucose tolerance test (IVGTT) and morphologic examination of pancreas using immunohistochemical stain, in situ end-labeling method and electron microscopic study were performed. Various mitochondrial parameters were measured by image analyzer. Immunohistochemical stain revealed a markedly reduced islet size and decreased number of beta-cells and the increased number of non-beta-cell in adult and neonatoal streptozotocin group, and the appearance of insulin positive cells throughout the exocrine parenchyma in neonatal streptozotocin group. Three days after injection of streptozotocin in adult streptozotocin group, TUNEL stain showed increased apoptotic cells in islets. Ultrastructurally, beta-cells in adult streptozotocin group showed increase in number and size of mitochondria, and disruption of mitochondrial structures. Hyperglycemic group and neonatal streptozotocin group showed preserved mitochondrial ultrastructure. Ultrastructural morphometric study revealed increase in size and number of mitochondria and decrease in mitochondrial contour index in adult streptozotocin-treated rats, which suggested mitochondrial degeneration. Hyperglycemic group showed mild increase in size of mitochondria. Increased number of mitochondria was also observed in neonatal streptozotocin group. IVGTT revealed marked decrease in insulin response in adult streptozotocin group, and non-insulin-dependent diabetes mellitus pattern in glucose and insulin response in neonatal streptozotocin group. Hyperglycemic group showed a glucose and insulin response similar to control group. The above results suggest that a severe oxidative injury may cause degeneration and disruption of mitochondria of pancreatic beta-cell, and may be associated with substantial apoptotic cell death. The changes in the morphology and the number of mitochondria may result from streptozotocin treatment within neonatal period and hyperglycemia treatment, which may be associated with changes in insulin response.
