Phorbol ester and okadaic acid-resistant cells: the crossroads of signal transduction and drug resistance

The American Journal of Medicine

Abstract

Many factors are involved in the development of drug resistance for anticancer drugs. The drugs should pharmacokinetically attain the appropriate concentration. They should be metabolized to the active forms. Tumor cells should have sensitivity to them. Several molecular and biochemical mechanisms that may explain cellular drug resistance have been identified. The contribution of protein phosphorylation and dephosphorylation for drug resistance is demonstrated in phorbol ester and okadaic-acid-resistant cells. The modulation of drug resistance by substances that affect the signal transduction pathway is an important issue in the development of an effective method for overcoming drug resistance.

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.
