Mutation Analysis of TP53 Tumor Suppressor Gene in Colorectal Cancer in Patients from Iran (Kerman Province)

Objective(s) P53 is an important tumor suppressor, which is mutated in later stages of many cancers and leads to resistance to chemotherapy. The aim of this study was to reveal mutations of TP53 in colorectal cancer in Kerman province. Materials and Methods A total of Forty-three colon cancer specimens as paraffin block or fresh tissues, which passed stage IIIA, were selected. Three exons 5,...

Changes in Expression of miR-1297 and PTEN Tumor Suppressor Gene in T-cell Acute Lymphoblastic Leukemia

Background and purpose: T-cell acute lymphoblastic leukemia (T-ALL) is a type of blood malignancy caused by changes in the precursors of T lymphocyte cells. The PTEN gene is one of the most common tumor suppressor genes that mutates in most human cancers, including T-ALL. Therefore, it is important to identify miRNAs that target the PTEN gene in T-ALL. For this purpose, in the present study, mi...

Transcriptional activation of the tumor suppressor and differentiation gene S100A2 by a novel p63-binding site

S100A2 is generally found expressed in the epidermis and was recently shown to play a crucial role in the differentiation of keratinocytes. Also known as CaN19, S100A2 was identified as a potential tumor suppressor. Expression of S100A2 is upregulated by p53. The proteins p63 and p73 are related to p53 and are expressed as several splice variants with partially overlapping tasks but also functi...

Regulation of B cell homeostasis and activation by the tumor suppressor gene CYLD

B cell homeostasis is regulated by multiple signaling processes, including nuclear factor-kappaB (NF-kappaB), BAFF-, and B cell receptor signaling. Conditional disruption of genes involved in these pathways has shed light on the mechanisms governing signaling from the cell surface to the nucleus. We describe a novel mouse strain that expresses solely and excessively a naturally occurring splice...
