Antecedents and Outcomes of Nurses' Subjective Career Success: A Path Analysis

Purpose This study aimed to test the hypothesis model showing the relationship between nurses' individual and working characteristics, nursing work environment, subjective career success, job satisfaction, intent to leave, and professional commitment

Inhibition characteristics of hypericin on rat small intestine glutathione-S-transferases

Glutathione-S-transferases constitute a family of enzymes involving in the detoxification of xenobiotics, signalling cascades and serving as ligandins or/and catalyzing the conjugation of various chemicals and drugs. The widely expressed cytosolic GST-pi is a marker protein in various cancers and its increased concentration is linked to drug resistance. GST-pi is autoregulated by S-glutathionylation and it catalyzes the S-glutathionylation of other proteins in response to oxidative or nitrosative stress. S-glutathionylation of GST-pi results in multimer formation and the breakage of ligand binding interactions with c-Jun NH(2)-terminal kinase (JNK). Another widely expressed GST enzyme, GST-alpha is assumed as a marker in hepatocellular damage, is implicated in cancer, asthma, cardiovascular disease and response to chemotherapy

Amitriptyline may have a supportive role in cancer treatment by inhibiting glutathione S-transferase pi (GST-pi) and alpha (GST-alpha)

A tricyclic anti-depressant, amitriptyline, is a highly prescribed drug for cancer patients for mood elevation but there are limited studies about the interaction of amitriptyline with glutathione S-transferases pi (GST-pi) and glutathione S-transferases alpha (GST-alpha). GST isozymes have been implicated in chemotherapeutic drug resistance. We demonstrated that the concentration dependent inhibition of GST-pi and GST-alpha by amitriptyline followed inverse hyperbolic inhibition curves with IC50 values of 5.54 and 8.32 mM, respectively
