Background: Involvement of mutations in epigenetic mechanism in the development of heterogeneous MDS and its evolution to AML has been understood with at least one mutation and median of 2-3 mutations of the landscapes of driver mutations in ~40 genes described in >90% MDS patients. Exclusivity and cooperating effects of mutations have directed therapeutic implementation with hypomethylating agents and id Read More

Background: Aldo-keto reductase 1C3 (AKR1C3) is an important oxidoreductase with multiple substrates, that are involved in producing extra-testicular androgens. Its activity is influenced by environmental exposures, as well as by genetic variants. These genetic variants could therefore produce variable testosterone levels and subsequent androgen receptor (AR) activation. This could lead to differential downstream prod Read More

Background: Epidermal growth factor receptor (EGFR) is a well-recognised drug target exploited for treating non-small cell lung cancer (NSCLC). Gefitinib and erlotinib are first generation clinically employed inhibitors used against EGFR activating mutants. However, during course of treatment these inhibitors become ineffective due to the emergence of an acquired secondary mutation. Subsequently, in order to overcome non- Read More

Background: Cyclin-dependent kinase (CDK) 4/6 inhibitor-based therapies have shown great promise in improving clinical outcomes for patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer. Objectives: 1. Discuss the mode of action of the three CDK4/6 inhibitors in late clinical development: palbociclib (PD-0332991; Pfizer), ribociclib (LEE011; Novar Read More

Background: Osteosarcoma is the most frequent malignant bone tumor in childhood and young adulthood. Long-term survivors of osteosarcoma patients show high prevalence of osteoporosis and fractures. The immunomodulatory mifamurtide, which modulates macrophages activity, improves disease outcome. Objective: To evaluate the role of mifamurtide on macrophage component of bone, the osteoclasts, during c Read More

Background: DNA topoisomerase II-α (Top2-α), an essential enzyme for the management of DNA during replication, transcription, recombination, and chromatin remodeling, is one of the most important anticancer targets. Numerous molecules have been designed as Top2-α inhibitors. However, several studies have shown that polymorphisms and mutations in Top2 have conferred resistance to most of these anticancer Read More

Background: Resveratrol has been shown to have antioxidant and anti-proliferative properties in multiple cancer types. Here we demonstrate that H460 lung cancer cells are more susceptible to resveratrol treatment in comparison to human bronchial epithelial Beas-2B cells. Resveratrol decreases cell viability and proliferation, and induces significant apoptosis in H460 cells. The apoptosis observed was accompanied by a Read More
