Endoplasmic reticulum stress triggered by Soyasapogenol B promotes apoptosis and autophagy in colorectal cancer
Publication date: Available online 14 December 2018Source: Life SciencesAuthor(s): Luping Wang, Lu Yun, Xiaojun Wang, Liying Sha, Luning Wang, Yingying Sui, Hui ZhangAbstractAimColorectal cancer (CRC) is a common human malignancy which accounts for 600,000 deaths annually at the global level. Soyasapogenol B (Soy B), an ingredient of soybean, has been found to exert anti-proliferative activities in vitro in human breast cancer cells. The current study aimed to evaluate the efficacy of Soy B in suppressing CRC.Methods and materialsThe effect of Soy B on cell viability was assessed using the Cell Counting Kit-8 (CCK-8) assay...

Gene therapy for colorectal cancer by adenovirus-mediated siRNA targeting CD147 based on loss of the IGF2 imprinting system.
Abstract Colorectal cancer (CRC) is one of the most common malignant tumors worldwide. Loss of imprinting (LOI) of the insulin-like growth factor 2 (IGF2) gene is an epigenetic abnormality phenomenon in CRC. Recently observed association of CRC with cluster of differentiation 147 (CD147) could provide a novel approach for gene therapy. In the present study, we investigated the feasibility of using adenovirus‑mediated siRNA targeting CD147 based on the IGF2 LOI system for targeted gene therapy of CRC. A novel adenovirus-mediated siRNA targeting CD147, rAd-H19-CD147mirsh, which was driven by the IGF2 imprintin...

Haploinsufficiency of the c-myc transcriptional repressor FIR, as a dominant negative-alternative splicing model, promoted p53-dependent T-cell acute lymphoblastic leukemia progression by activating Notch1.
In conclusion, the alternative splicing of FIR, which generates FIRΔexon2, may contribute to both colorectal carcinogenesis and leukemogenesis. PMID: 25671302 [PubMed - as supplied by publisher]
