Transplantation of IL-1 β siRNA-modified bone marrow mesenchymal stem cells ameliorates type II collagen-induced rheumatoid arthritis in rats
Exp Ther Med. 2022 Feb;23(2):139. doi: 10.3892/etm.2021.11062. Epub 2021 Dec 14.ABSTRACTRheumatoid arthritis (RA) is a chronic autoimmune disease that causes erosion of articular cartilage and bone and has adverse effects on both patients and livestock animals. The aim of the present study was to investigate the role of interleukin-1β (IL-1β) in the pathogenesis of RA, and to further determine whether injection of IL-1β small interfering RNA (siRNA) or transplantation of IL-1β siRNA + bone marrow mesenchymal stem cells (BMSCs) can ameliorate RA in rats. A collagen-induced arthritis (CIA) rat model was established by in...

Effect of dihydroarteminin combined with siRNA targeting Notch1 on Notch1/c-Myc signaling in T-cell lymphoma cells.
Authors: Huo L, Wei W, Wu S, Zhao X, Zhao C, Zhao H, Sun L Abstract The effectiveness of therapy combining dihydroartemisinin (DHA) and small interfering RNA targeting Notch1 (siNotch1) in T-cell lymphoma remains unknown. The present study explored the potential and possible mechanisms of combined dihydroarteminin, and siNotch1 therapy for T-cell lymphoma. It was demonstrated that the viability rates of siRNA-DHA-treated cells was significantly suppressed in comparison with those in control cells, control siRNA cells, siRNA-treated cells and DHA-treated cells (P<0.01). Additionally, there was a significant incre...

Effects of siRNA-mediated suppression of HPV-11 L1 expression on the proliferation and apoptosis of vaginal epithelial cells.
Authors: Zeng J, Yang S, Wang X, Gao Y, Zhang M Abstract The aim of the present study was to investigate the effects of human papillomavirus (HPV) infection on the gynecological disease of vaginitis and to demonstrate how the small interfering RNA (siRNA) method may be used for HPV prevention in the clinic. Human vaginal epithelial cells were transfected with HPV-11 L1 expression vector and siRNA-HPV-11 L1 vectors and a control group was transfected with scrambled siRNA. Cell proliferation in each group was analyzed using the MTT assay and the expression of apoptosis-associated proteins was measured by western blot...

Exosomes as nanocarriers for siRNA delivery: paradigms and challenges.
Authors: Shahabipour F, Banach M, Sahebkar A Abstract Exosomes are nano-sized vesicles that facilitate intercellular communications through carrying genetic materials and functional biomolecules. Owing to their unique size and structure, exosomes have emerged as a useful tool to overcome the limitations of siRNA delivery. The use of exosomes as siRNA delivery vehicles lacks certain disadvantages of the existing foreign delivery systems such as viruses, polycationic polymers and liposomes, and introduces several advantages including inherent capacity to pass through biological barriers and escape from phagocytosis b...

Expression of ectonucleotide pyrophosphatase-1 in end-plate chondrocytes with transforming growth factor beta 1 siRNA interference by cyclic mechanical tension.
CONCLUSION: CMT increases the expression of ENPP-1 in end-plate chondrocytes in a manner likely dependent on TGF-β induction by the ERK1/2 signaling pathway. PMID: 24157151 [PubMed - in process]

siRNA-mediated downregulation of GluN2B in the rostral anterior cingulate cortex attenuates mechanical allodynia and thermal hyperalgesia in a rat model of pain associated with bone cancer.
Authors: Xu Y, Wang G, Zou X, Yang Z, Wang Q, Feng H, Zhang M Abstract It has previously been suggested that the upregulation of GluN2B-containing N-methyl D-aspartate receptors (GluN2B) within the rostral anterior cingulate cortex (rACC) may contribute to the development of chronic pain. The present study used a rat model of bone cancer pain in order to investigate whether lentiviral-mediated delivery of small interfering RNAs targeting GluN2B (LV-GluN2B) could attenuate pain associated with bone cancer, by selectively decreasing GluN2B expression within the rACC. Sprague Dawley rats were inoculated with osteosarc...

The siRNA silencing of DcR3 expression induces Fas ligand-mediated apoptosis in HepG2 cells.
Authors: Zhao T, Xu Y, Ren S, Liang C, Zhou X, Wu J Abstract Dysfunctional Fas ligand (FasL) may inhibit the apoptosis of tumor cells. FasL contains two receptors, Fas and Decoy Receptor 3 (DcR3). DcR3 competitively binds to FasL over Fas, resulting in the inhibition of FasL-mediated apoptosis. Therefore, it was suggested that the downregulation of DcR3 expression enhances FasL-mediated apoptosis. In the current study, the expression of DcR3 was silenced in liver cancer HepG2 cells in order to study the effect of FasL on HepG2 cell activity and invasiveness. DcR3 siRNA knockdown HepG2 cells (KD), DcR3 blank plasmid...

Tip60-siRNA regulates ABCE1 acetylation to suppress lung cancer growth via activation of the apoptotic signaling pathway.
Authors: Liang Z, Yu Q, Ji H, Tian D Abstract Lung cancer is a leading cause of cancer-associated mortality and morbidity worldwide. Previous studies have suggested that ATP-binding cassette transporter E1 (ABCE1) acetylation is upregulated in the tissues and cells of lung cancer and is associated with the prognosis of patients with lung cancer. The aim of the present study was to investigate the association between Tat interactive protein 60 kDa (Tip60) expression and ABCE1 acetylation, and the effect of Tip60 on the biological functions of A549 lung carcinoma cells. The expression levels of Tip60 and ABCE1 acetyl...
