Little is known about biogenically synthesized Zinc oxide nanoparticles (ZnONPs) from Isodon rugosus . Synthesis of metal oxide NPs from essential oil producing medicinal plants results in less harmful side effects to the human population as compared to chemically synthesized NPs. In this article, we report biogenic synthesis of ZnONPs from in vitro derived plantlets and thidiazuron (TDZ) induced callus culture of Isodon rugosus . Synthesized NPs were characterized using UV-spectra, XRD, FTIR, SEM and EDX. Furthermore, the NPs were evaluated for their potential cytotoxic (against HepG2 cell line) and antimicrobial (against drug resistant Staphylococcus epidermidis , Bacillus subtilis , Klebsiella pneumoniae and Pseudomonas aeruginosa ) activities...

Bone is one of the most common sites of complication in multiple myeloma (MM) progression and bone remodeling gets definitively perturbed during disease progression. Hypoxia and miR-210 play an important role in hematological malignancies. In an attempt to elucidate the specificity of the pathways of hypoxia and miR-210 in suppression of osteoblastic differentiation in MM patients, we examined the effect of miR-210 and hypoxia on expression of important cytokines and genes of myeloma cells. Differentiation of BM-MSCs towards osteoblastic cells in response to microvesicles (MVs) was also investigated...

Aging is often accompanied by a decline in cognitive function in conjunction with a variety of neurobiological changes, including neuroinflammation. Melatonin is a key endogenous indoleamine secreted by the pineal gland that plays a crucial role in the regulation of circadian rhythms, is a potent free radical scavenger, has anti-inflammatory activity and serves numerous other functions. However, the role of melatonin in sterile inflammation in the brain has not been fully investigated. In the present study, we investigated the neuroinflammation status in aged mouse brains...

Avelumab is an anti-PD-L1 (programmed death-ligand 1) immune checkpoint inhibitor (ICIs) and the monoclonal antibody that constitutes a major development in the immunotherapy of cancer. In 2017, The European Medicine Agency (EMA) approved it as an orphan drug for treatment of gastric cancer. Avelumab has recently been approved in the United States, Europe and Japan for treatment of metastatic Merkel cell carcinoma (MCC). Avelumab inhibits the interaction of Programmed cell death protein 1 (PD-1) on immune cells with PD-L1 on tumor cells, thus banishing immunosuppressive signals and leading to enhanced immune cell activation...

Obesity is associated with higher postmenopausal breast cancer incidence. Visfatin level alteration is one of the mechanisms by which obesity promotes cancer. Ligand-independent activation of estrogen receptor alpha (ERα) is also associated with carcinogenesis. The activity of ERα is modulated through phosphorylation on multiple sites by a number of protein kinases. Here we investigated the effect of visfatin as a novel adipocytokine on the phosphorylation and activity of ERα in MCF-7 breast cancer cells...
