Potential of siRNA-albumin complex against cancer

Publication date: Available online 27 April 2018Source: Chemico-Biological InteractionsAuthor(s): Na Liu, Yan-Hua Qi, Chuan-Tao Cheng, Wen Bin Yang, Anshoo Malhotra, Qi ZhouAbstractRNA interference is a highly specific as well as efficient technology for gene therapy application in molecular oncology. The present study was planned to develop an efficient and stable tumor selective delivery mechanism for siRNA gene therapy for the purpose of both diagnosis as well as therapy. We have used 20 Male wistar rats for the formation of colon cancer model and utilized albumin as carrier molecule for the delivery of siRNA against vascular endothelial growth factor receptor 2 (VEGF R2). The study results confirmed efficient delivery of siRNA at tumor site as confirmed by tagging of siRNA-albumin complex with 99mTC. Moreover, the expression of VEGF also showed decline after efficient delivery of siRNA at tumor site. The study concluded that albumin is an efficient molecule for the efficient delivery of siRNA at tumor sites.

Mutations in Tumor Protein P53 (p53) are expressed in a variety of human cancers such as cholangiocarcinoma, melanoma, colon cancer, rectal cancer, ovarian cancer, endometrial cancer, non-small cell lung cancer (NSCLC), glioblastoma, uterine cervical cancer, head and neck cancer, breast cancer, pancreatic cancer, and bladder cancer. The p53 protein is involved in determining whether DNA is repaired or the damaged cell undergoes apoptosis – thus acting as a tumor suppressor by regulating cell division. Mutations in the p53 protein can reduce or eliminate its tumor suppressor function or interfere with wild type p53 in...

Conclusion: The expression of miR-155 is up-regulated in colonic cancer tissues. MiR-155 may acts as proto-oncogenes involved in carcinogenesis, development, and invasion of colon cancer making it a potential target for gene therapy of colon cancer.

An interesting observation that has arisen over the years of epidemiological study of human age-related disease is that there are a number of distinct inverse relationships between incidence of cancer and incidence of some forms of neurodegeneration. This was in the news a few years ago in the case of Alzheimer's disease for example. Why would people with a higher risk of cancer suffer lower rates of Alzheimer's disease, however? We can only speculate at this point, but the more recent discovery I'll point out here adds fuel for that speculation. The Alzheimer's-cancer relationship is modest in size and somewhat complex in...

Authors: Ye L, Yang Y, Ma XY, Li D, Xu ML, Tan P, Long LM, Wang HQ, Liu T, Guo YH Abstract Despite progress achieved in cancer chemotherapy in recent decades, adverse effects remain a limiting factor for a number of patients with colorectal cancer, suggesting the requirement for novel therapeutic strategies. Gene therapy appears to be a promising strategy for treating cancer. The present study aimed to investigate the anti-tumor effect of a combined gene therapy, using Survivin downregulation by RNAi and a fusion suicide gene yCDglyTK therapy system. A triple-gene vector expressing Survivin-targeted small hairpin R...
