We aimed to identify STK31 as a cancer-testis (CT) gene and to explore its potential clinical value, regulatory mechanisms, and gene network in pancreatic cancer (PC). Gene expression data were generated from normal organ samples and pancreatic cancer samples from three public databases. STK31 expression patterns in normal and PC tissues were identified, and we explored its regulatory mechanism...

Objective(s):Cyclophosphamide (CP) toxicity on testis was hampered by squid ink polysaccharide (SIP) via restoration of antioxidant ability in our previous investigations. This study investigated roles of Nrf2/ARE signal pathway in testis of treated mice. Materials and Methods: Male Kunming mice were employed to undergo treatment with SIP and/or CP. Protein levels of Nrf2, keap-1, histone deac...

Genes MAGE, BAGE, GAGE, and LAGE-1/NY-ESO-1 code for antigens that are recognized on melanoma cells by autologous CTLs. Because the pattern of expression of these genes results in the presence of antigens on many tumors of various histological types and not on normal tissues, these antigens qualify for cancer immunotherapy. To identify new genes with tumor-specific expression, we applied a cDNA...

PURPOSE To isolate cancer testis antigens that are expressed in pancreatic cancers and may be useful in clinical applications. EXPERIMENTAL DESIGN To efficiently isolate cancer testis antigens, a testis cDNA library was immunoscreened (SEREX) with serum from a patient with pancreatic ductal adenocarcinoma. The expression of isolated antigens in various cancer cell lines and tissues was evalua...

Breast cancer is one of the most common cancers among women. To discover molecular targets that are applicable for development of novel breast cancer therapy, we previously did genome-wide expression profile analysis of 81 breast cancers and found dozens of genes that were highly and commonly up-regulated in breast cancer cells. Among them, we here focused on one gene that encodes PDZ-binding k...

The direction of gonadal development is established through the predominance of one of two sex-determining pathways in bipotential gonads. When Sry is expressed, the male pathway prevails and a series of prominent changes in morphology and function of the gonad lead to testis differentiation. In the absence of Sry, the female pathway gains control of gonadal development, resulting in a lack of ...

We previously reported some cancer testis antigens, especially for MAGE genes, to be expressed in a relatively high population of gastro-intestinal and breast cancers. TRAG-3 (Taxol resistant associated gene-3) may be another cancer testis antigen; however, its expression has still not been fully studied. The TRAG-3 expression was evaluated in a total of 57 cancer cell lines and 322 cancer samp...

background: the study of specific genes expressed in the testis is important to understanding testis development and function. spermatogenesis is an attractive model for the study of gene expression during germ cell differentiation. spermatogenesis associated-19 (spata-19) is a recently-identified important spermatogenesis-related gene specifically expressed in testis. its protein product is in...
