Keratin 36, a specific marker of tongue filiform papillae, is downregulated in squamous cell carcinoma of the mobile tongue.

Human keratin 36 (K36) is a member of the hair keratin family and is a marker of hair cortex differentiation. The human gene is located on the long arm of chromosome 17 and belongs to the cluster of structurally unrelated acidic hair keratins. Recently, it has been reported that mRNA is specifically expressed in normal tongue epithelium and downregulated in squamous cell carcinomas of the mobile tongue.

Oncogenic Viral Protein Interactions with p53 Family Proteins.

Background: Cellular transformation induced by oncogenic viruses is a complex process including viral molecules, host cells and environmental factors. Viruses alone are unable to reproduce and thus they need a host to use their signalling, proteosynthetic and metabolic pathways. One target host molecule is the p53 tumour suppressor.

Role of the Microbiome in the Formation and Development of Colorectal Cancer.

Background: The clinical, histopathological, and molecular characteristics of colorectal cancer vary considerably. Factors associated with the heterogeneity of this disease and with understanding the effects of heterogeneity on disease progression and response to therapy are critical for the better stratification of patients and the development of new therapeutic methods. Although studies have focused mainly on tumor molecular profiling, current molecular predictive and prognostic factors are relevant to specific groups of colorectal cancer patients and are mostly used to predict the applicability of targeted biological agents rather than to predict their benefits.

Tomm34 is commonly expressed in epithelial ovarian cancer and associates with tumour type and high FIGO stage.

Background: Increased activity of the chaperones Hsp70 and Hsp90 is a common feature of solid tumours. Translocase of the outer mitochondrial membrane 34 (Tomm34) is a cochaperone of both Hsp70 and Hsp90 that was found to be overexpressed in colorectal, hepatocellular, lung and breast carcinomas. The expression profile of Tomm34 in ovarian cancer has not been investigated.
