BACKGROUND Cathelicidins and defensins are endogenous antimicrobial peptides (AMPs) that are downregulated in the mucosal epithelia of the large intestine in shigellosis. Oral treatment of Shigella infected rabbits with sodium butyrate (NaB) reduces clinical severity and counteracts the downregulation of cathelicidin (CAP-18) in the large intestinal(More)
RNA interference (RNAi) is a powerful approach in functional genomics to selectively silence messenger mRNA (mRNA) expression and can be employed to rapidly develop potential novel drugs against a complex disease like cancer. However, naked siRNA being anionic is unable to cross the anionic cell membrane through passive diffusion and therefore, delivery of(More)
Most of the classical drugs used today to destroy cancer cells lead to the development of acquired resistance in those cells by limiting cellular entry of the drugs or exporting them out by efflux pumps. As a result, higher doses of drugs are usually required to kill the cancer cells affecting normal cells and causing numerous side effects. Accumulation of(More)
Treatment of shigellosis in rabbits with phenylbutyrate reduces clinical severity and counteracts down-regulation of cathelicidin (CAP-18) in the large intestinal epithelia. We aimed to further evaluate whether in a rabbit model of enteropathogenic Escherichia coli (EPEC) diarrhea, CAP-18 is down-regulated in the small intestine and if oral phenylbutyrate(More)
Despite being widely used for treating cancer, chemotherapy is accompanied by numerous adverse effects as a result of systemic distribution and nonspecific interactions of the drugs with healthy tissues, eventually leading to therapeutic inefficacy and chemoresistance. Cyclophosphamide (Cyp) as one of the chemotherapeutic pro-drugs is activated in liver and(More)
Treatment of breast cancer, the second leading cause of female deaths worldwide, with classical drugs is often accompanied by treatment failure and relapse of disease condition. Development of chemoresistance and drug toxicity compels compromising the drug concentration below the threshold level with the consequence of therapeutic inefficacy. Moreover,(More)
