Association between the Trp64Arg polymorphism of the ADRB3 gene and overactive bladder.

Background: The β -adrenergic receptor (ADRB3) is very important in the regulation of the human detrusor muscle function. The well-known tryptophan64arginine polymorphism of the ADRB3 gene alters the response of the receptor to various stimuli, including adrenalin and noradrenalin, and may increase the susceptibility to develop overactive bladder (OAB). Therefore, this study was performed to determine whether ADRB3 Trp64Arg polymorphism is associated with the pathophysiology of OAB syndrome.

The Possible Interactions and Therapeutic Roles of Lithium Chloride and Midkine on Cancer Treatment.

Midkine (MK) is a heparin-binding anti-apoptotic growth factor or cytokine also known as neurite growth-promoting factor 2 (NEGF2). It is developmentally an important retinoic acid-responsive gene product strongly induced during the mid-gestation stage. Midkine promotes different cellular events such as cell growth, differentiation, survival, gene expression, and drug resistence.

Inhibition of midkine by metformin can contribute to its anticancer effects in malignancies: A proposal mechanism of action of metformin in context of endometrial cancer prevention and therapy.

Metformin, a drug widely used in the treatment of type II diabetes mellitus (T2DM), has been the focus of interest as a potential therapeutic agent for certain types of malignancies, including gynaecological cancers [i.e. endometrial cancer (EC)].

Dual inhibition of P-glycoprotein and midkine may increase therapeutic effects of anticancer drugs.

Multidrug resistance (MDR) to chemotherapy may significantly affect the outcome of cancer treatment. ATP-dependent drug efflux pumps, including P-glycoprotein (P-gp), contribute to the resistance of various chemotherapeutic agents. Overexpression of P-gp in tumor cells induces chemoresistance via pumping the anticancer drugs out of the cells.
