Expression analysis of MKK6 protein in solid tumors has never been investigated. Here, we report systematic analysis of MKK6 protein in different types of human tumor samples using western blotting and immunofluorescence techniques. We observed significant increase in the expression of MKK6 in Esophageal, Stomach, and Colon cancers as compared to controls. Results were alternately confirmed by Immunofluorescence studies. Upregulation of MKK6 protein is indicative of its role in human cancers and could possibly be used as a novel diagnostic or prognostic marker in these cancers.

The expression of E3B1/ABI-1 protein and its role in cancer progression and prognosis are largely unknown in the majority of solid tumors. In this study, we examined the expression pattern of E3B1/ABI-1 protein in histologically confirmed cases of esophageal (squamous cell carcinoma and adenocarcinoma), gastro-esophageal junction, colorectal cancers and corresponding normal tissues freshly resected from a cohort of 135 patients, by Western Blotting and Immunofluorescence Staining. The protein is present in its phosphorylated form in cells and tissues. Depending on the extent of phosphorylation it is either present in hyper-phosphorylated (M. Wt. 72 kDa) form or in hypo-phosphorylated form (M. Wt. 68 kDa and 65 kDa). A thorough analysis revealed that expression of E3B1/ABI-1 protein is significantly decreased in esophageal, gastro-esophageal junction and colorectal carcinomas irrespective of age, gender, dietary and smoking habits of the patients. The decrease in expression of E3B1/ABI-1 was consistently observed for all the three isoforms. However, the decrease in the expression of isoforms varied with different forms of cancers. Down-regulation of E3B1/ABI-1 expression in human carcinomas may play a critical role in tumor progression and in determining disease prognosis.

Background: Testicular and paratesticular neoplasia are rare type of tumors affecting adolescents and young adults in India, as observed by paucity of published data. This study was undertaken to analyze the patterns of testicular tumors at a tertiary level hospital in Kashmir valley, Jammu and Kashmir, India highlighting the patient’s demography, clinical presentation, diagnostic evaluation and pathological finding.Methods: This 5-year (retrospective and prospective) study was performed in the Department of Pathology, Government Medical College Srinagar, Jammu and Kashmir, India from January 2012 to December 2016. For the retrospective study, all cases of testicular tumors, their histopathological reports and required clinical details were searched from records maintained in the Department of Pathology, GMC Srinagar, Jammu and Kashmir, India. For the prospective study, the orchiedectomy specimens received in our department were subjected to routine histopathological processing followed by a detailed gross and microscopic examination. Tumour typing and subtyping was done according to WHO classification (2004).Results: A total of 37 cases of testicular and paratesticular neoplasia were included in present study with a mean age of 35.1 years. Out of these 37 cases, 31 (83.78%) were malignant and 6 cases (16.22%) were benign. Right testis was affected in 70.3% of cases. The most common clinical presentation was scrotal swelling. Germ cell tumor was the most common type accounting for 89.2% of tumors followed by lymphomas (8.1%).Conclusions:It is concluded that despite new techniques in imaging and tumor marker assay, the diagnosis of testicular tumors is dependent upon histopathological examination. The present study fairly provides an insight into the clinical presentations, prevalence and patterns of testicular tumors.

The present study was carried out in the postgraduate department of Pathology at Government Medical College, Srinagar, India, to study the histopathological pattern of primary bone tumors in Kashmir valley over a period of 15 years. During this study, 373 histologically proven primary bone tumors were analyzed. Out of these, 298 were benign (79.89%) and 75 were malignant (20.10%). Peak incidence was in the second and third decade of life with male predominance. Among the malignant tumors, the highest incidence was that of Osteosarcoma (52%), followed by Ewing's sarcoma (24%) and Chondrosarcoma (14%). Osteochondroma (49%) was the most frequent tumor in the benign category. The most commonly affected bones were femur, tibia and humerus in that order. Comparison with similar studies from other parts of the globe indicate that the relative frequency of primary bone tumors appears to be low but shows a rising trend in the last 10 years in this part of the world.
