This back cover shows a novel delivery vehicle of RNA nanoparticle (named RIONmiR-143) for RAS-mutated intractable cancers. Tumor-suppressor microRNA-143 (miR-143) silences oncogenic KRAS networks, but it lacks nucleic acid clinical application. research creates the RIONmiR-143 by self-assembly miR-143s and demonstrates functions.

Carcinogenesis is a multistep process attributable to both gain-of-function mutations in oncogenes and loss-of-function mutations in tumor suppressor genes. Currently, most molecular targeted therapies are inhibitors of oncogenes, because inactivated tumor suppressor genes have proven harder to "drug." Nevertheless, in cancers, tumor suppressor genes undergo alteration more frequently than do o...

RASSF1A (Ras association domain family 1 isoform A) is a recently discovered tumor suppressor whose inactivation is implicated in the development of many human cancers. Although it can be inactivated by gene deletion or point mutations, the most common contributor to loss or reduction of RASSF1A function is transcriptional silencing of the gene by inappropriate promoter methylation. This epigen...

Carcinogenesis is a multistep process in which cells accumulate multiple genetic alterations as they progress to a more malignant phenotype. Allelic chromosomal losses as well as mutations of tumor suppressor genes are common genetic events in the development and/or progression of both hereditary and non-hereditary tumors. Recent studies have shown a direct correlation between malignancy and in...

Background Beta cell dysfunction and death are critical steps in the development of both type 1 2 diabetes (T1D T2D), but underlying mechanisms incompletely understood. Activation essential tumor suppressor transcription factor P53 was linked to beta vitro has been reported several mouse models cells humans with T2D. Therefore, we investigated specific role dysfunction, vivo.

background :many breast cancer tumor suppressor genes have been reported to undergo hypermethylation, including er, rassf1a, hic, cdh1, gspt1, apc, twist and ccnd2. we first determined the promoter methylation of the above eight tumor suppressor genes as epigenetic markers of breast cancer in three cell lines with different er status. methods : this study was an experimental study performed on ...

Colorectal cancer is the cause of death for some 600,000 people per year in the world and patient numbers are still increasing. Risk of colorectal cancer is greatly increased by inherited factors, lifestyle (smoking or alcohol consumption) and microbial infections causing bowel inflammation (colitis). The prolongation of colitis leads to tumorigenesis. The mechanism by which chronic colitis dev...
