background: the role of retinoblastoma (rb) protein in cell cycle regulation prompted us to take up this study with the aim of assessing its role in the progression of oral cancer and to correlate with various clinicopathological parameters, including habits such as smoking, paan chewing, and alcoholism. materials and methods: this observational study included surgical specimens from 10 apparen...

Gastric cancer (GC) is a major malignancy in many developing countries with low early detection rate. As tumour suppressor gene, WTX inhibits PI3K/AKT/mTOR pathway activity by inhibiting PI3K phosphorylation. loss of protein associates tumor metastasis and poor survival GC patients. During progression, an aberrantly elevated miR-20a-5p expression has been found, which induces phosphorylation, t...

The multiple tumor suppressor gene l (MTS1) located on chromosome 9p has recently been implicated as a candidate tumor suppressor gene in many different tumor types. Cytogenetic analysis and deletion mapping studies have revealed that deletion of chromosome 9p occurs in a signif icant number of primary human astrocytomas. Using multiplex PCR with primers for exon 2 of MISI and for D9S196 from c...

Allele loss on a specific chromosome has implied the existence of a tumor suppressor gene such as the p53 gene and the RB gene. In order to determine which chromosome(s) carries a tumor suppressor gene(s) that contributes to tumor progression in primary breast cancer, we analyzed the loss of heterozygosity for each autosomal chromosome arm by using 39 restriction fragment length polymorphism ma...

familial adenomatous polyposis (fap) is responsible for < 1% of colorectal cancer (crc) cases and is inherited as an autosomal dominant trait. patients generally present hundreds to thousands of adenomas and develop colorectal cancer by age 35- 40 if left untreated. here we report four patients with germline frameshift mutation (small deletion) at exon 15 of adenomatous polyposis coli (apc) tum...
