Context: Diabetic cardiomyopathy (DCM) is associated with suppressed autophagy and augmented apoptosis in the heart although the interplay between the two remains elusive. The ability of mammalian sterile 20-like kinase 1 to regulate both autophagy and apoptosis prompted us to investigate it as a possible candidate in the progression of DCM.', 'Wild-type, Mst1 (also known as Stk4) transgenic and Mst1-knockout mice were challenged with streptozotocin to induce experimental diabetes. In addition, cultured neonatal mouse cardiomyocytes were subjected to simulated diabetes to probe mechanisms.', 'Mst1 knockout alleviated while Mst1 overexpression aggravated cardiac dysfunction in diabetes. Diabetic Mst1 transgenic mice exhibited decreased LC3 expression and enhanced protein aggregation. In contrast, typical autophagosomes were observed in diabetic Mst1-knockout mice with increased LC3 expression and reduced protein aggregation. Mst1 downregulation promoted autophagic flux as demonstrated by increased LC3-II and decreased p62 expression in the presence of bafilomycin A1. Furthermore, Mst1 overexpression increased, while Mst1 knockout decreased, cardiomyocyte apoptosis both in vivo and in vitro. Co-immunoprecipitation assays showed that Mst1 overexpression promoted Beclin1 binding to B cell lymphoma 2 (Bcl-2) and induced dissociation of Bcl-2 from Bax in diabetic mice. Conversely, Mst1 knockout disrupted the Beclin1-Bcl-2 complex and enhanced the interaction between Bcl-2 and Bax.
Answer: Mst1 knockout restores autophagy and protects against apoptosis in cardiomyocytes, en route to the rescue against DCM.
Does mST1 coordinately regulate autophagy and apoptosis in diabetic cardiomyopathy in mice?

Context: Isotretinoin is effective in the treatment of severe acne and rosacea. Both parent drug and its main metabolite 4-oxo-isotretinoin are potentially teratogenic compounds and contain a carboxylic acid moiety. In the presence of ethanol, naturally occurring as well as synthetic retinoids also containing a carboxylic acid moiety are capable of undergoing an ethyl esterification with the metabolic formation of more lipophilic compounds with a much longer terminal half-life.', 'To determine if isotretinoin (13-cis-RA), its main metabolite 4-oxo-isotretinoin (4-oxo-13-cis-RA), and other possible metabolites in the presence or absence of ethanol are converted to their corresponding ethyl derivatives in patients with severe acne or rosacea after multiple isotretinoin dosing. In addition, pharmacokinetic parameters of the parent drug and its 4-oxo metabolite were determined.', 'Eleven patients with severe acne or rosacea were treated with isotretinoin daily for 3 months and investigated pharmacokinetically during 24 h after 1 month of treatment and for up to 28 days after discontinuation of therapy. A possible influence of ethanol was evaluated using a simple self-administered questionnaire and by measuring serum ethanol levels during treatment. The concentrations of isotretinoin, 4-oxo-isotretinoin and possible ethylated and nonethylated metabolites were measured by reverse-phase high-performance liquid chromatography.', "Although seven of 11 patients had a considerable weekly alcohol intake, no endogenous synthesis of ethyl derivatives of isotretinoin, the main 4-oxo metabolite or the all-trans compounds was chromatographically detectable in any of the patients' plasma samples during the treatment period. Multiple dose pharmacokinetic data for the parent drug and its main metabolite were comparable to previous studies.
Answer: The metabolism and pharmacokinetics of isotretinoin and its main metabolites are not influenced by ethanol during long-term isotretinoin treatment. After ceasing long-term isotretinoin therapy the recommended period of 1 month for using anticonceptive measures in fertile women seems adequate.
Are the metabolism and pharmacokinetics of isotretinoin in patients with acne and rosacea influenced by ethanol?

Context: The objective was to evaluate the effect of dexamethasone and platelet transfusion treatment on recovery in patients with class 1 hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome.', 'All women with class 1 HELLP syndrome (true HELLP syndrome) who were seen at the hospital Complejo Hospitalario de la Caja de Seguro Social de Panama, Panama between July 1996 and June 2004 took part in a retrospective, comparative study. They were divided into two groups. One group received dexamethasone and the other group received dexamethasone plus platelet transfusion. True HELLP syndrome was defined as hemolysis, elevated liver enzymes, and maternal platelet nadir < or =50,000 platelets/microl.', 'The primary endpoint was resolution of the HELLP syndrome as recognized by normalization of the platelet count (> or =150,000/microl) and the mean length (measured in days) of the postpartum stay in hospital.', 'Forty-six women with true HELLP syndrome were studied. Twenty-six patients received dexamethasone and 20 received dexamethasone plus platelet transfusion. The normalization of the platelet count was significantly more rapid in the dexamethasone group (p<0.004) and the postpartum hospital stay was significantly more prolonged in the dexamethasone plus platelet transfusion group (p<0.02). There was no maternal death.
Answer: The findings suggest the initiation of high-dose dexamethasone therapy in women with true HELLP syndrome, with the next step being delivery, and probably platelet count < or =50,000/microl alone is not always an indication for platelet transfusion.
Does addition of platelet transfusions to corticosteroids increase the recovery of severe HELLP syndrome?
