Fragile histidine triad (FHIT) serves a critical function as a tumor suppressor that inhibits p53 degradation by mouse double minute 2 (MDM2). The functional domains of FHIT involved in tumor inhibition was interpreted. In-silico screening data were employed to construct truncated forms of FHIT to assess their cytotoxic effects on the HT1080 cell line. Full FHIT expression was confirmed by west...

biomolecular behavior of tumor cells has become attractive to investigators. p53 as an oncosuppresor gene has been core of various studies and ki67 is a nuclear protein involved in proliferation process. stopping of onco-suppressor function theoretically allows proliferative system to get out of any control. in this case-control study we evaluated 50 patients with non small cell lung cancer, co...

Objective(s): The growing trend of research demonstrates that dynamic expression of two metastasis repressor classes (metastasis suppressor genes and anti-metastatic miRNA) has a close relationship with tumor invasion and metastasis. Using different strategies, it was revealed that cellular levels of miR-31 and Breast cancer Metastasis Suppressor1 (BRMS1) protein, whic...

Marassi ........................................................................................ 3 2 Generation and Application of Phospho-Specific Antibodies for p53 and pRB Yoichi Taya, Kiichiro Nakajima, Kumiko Yoshizawa-Kumagaye, and K...

Abstract Piezoelectric nanomaterials have the ability to control cancer cells from a distance. Chronic stimulation using ultrasound-driven piezoelectric nanoparticles can reduce cell growth by inducing cycle arrest. This method presents promising solution minimize undesirable effects. Numerous in vitro studies with various types of shown that chronic interferes multiple oncogenes, tumor suppres...

Naturally occurring reoviruses are live replication-proficient viruses that specifically infect human cancer cells while sparing their normal counterpart. Since the discovery of reoviruses in 1950s, they have shown various degrees of safety and efficacy in pre-clinical or clinical applications for human anti-cancer therapeutics. I have recently discovered that cellular tumor suppressor genes ar...

Background &Aims: Laryngeal cancer is the second common cancer of respiratory tract, following the lung cancer. Carcinogenesis is a complex multistage process; molecular genetics has provided the evidence that activation of proto-oncogene and loss or inactivation of tumor suppressor genes (TSG) are involved in a large number of malignancies. One of the earliest significant tumor suppressor gene...

Ependymomas and astrocytomas commonly have allelic losses of chromosome 22q, which suggests the presence of a glioma tumor suppressor gene on 22q. A candidate tumor suppressor gene on 22q is the neurofibromatosis 2 (NF2) gene since NF2 patients have an increased susceptibility to ependymomas and astrocytomas. Using single strand conformation polymorphism analysis and direct DNA sequencing, we s...

Hepatocellular carcinoma (HCC) is one of the top five causes of cancer-related deaths worldwide. Recent developments in the treatment of HCC remain insufficient to cure unresectable disease or to prevent HCC. Consistent efforts are, therefore, needed to deepen understanding of pathogenesis of the disease. Genome-wide gene expression profile analyses can now detect various candidate genes that a...

Background & Objective: Papillary thyroid cancer (PTC) is considered to be the most common type of thyroid malignancies. Epigenetic alteration, in which the chromatin conformation and gene expression change without changing the sequence of DNA, can occur in some tumor suppressor genes and oncogenes. Methylation is the most common type of epigenetic alterations that can be an ex...
