Going through the Relationship in between Discussed Decision-Making, Patient-Centered Treatments, and Evidence-Based Medication.
Our findings indicate that FUNDC1 involves in receptor-mediated mitophagy separately from PINK1/Parkin-dependent mitophagy. Furthermore, inhibiting mitophagy by FUNDC1 or PINK1 knockdown accelerated rotenone-induced cytotoxicity. Taken together, our findings suggest that rotenone can be induced both receptor-mediated and PINK1/Parkin-dependent mitophagy for mitochondrial clearance, and that mitophagy by removing damaged mitochondria, has cytoprotective effects. Plant hormone brassinosteroids (BRs) have multiple important functions in plants. They have also been found to exhibit anti-tumor, anti-angiogenic and anti-proliferative activity. Selleckchem BI-2852 The experimental part of this article describes the effects of BR biosynthetic precursors on prostate cancer cells. The experiments were performed with LNCaP and DU-145 prostate cancer cell lines. These were cultivated and treated with tested BRs in different concentrations and time intervals. The tested compounds were found to affect cell viability, nuclear receptor expression, cell cycle and apoptosis in the tumor cells. IC50 concentrations were determined based on MTT test and the two most active compounds (cathasterone and 6-oxocampestanol) were used in the next experiments. Cathasterone was the most effective of all tested compounds and effectively inhibited integrity of cell spheres. It was found that both BRs had no significant effect on the cell cycle in LNCaP at IC50 concentration, while in DU-145 a significant block in G0/G1 phase after the BR treatment was observed. The effect of BRs on the nuclear steroid receptors was manifested by changes in their expression and localization. BRs demonstrated their significant effect on prostate cancer cells and the compounds have potential used in anticancer drug research and cancer treatment. Enniatin B is an emerging mycotoxin known to present biological activity because of its ionophoric characteristics. This compound has demonstrated strong in vitro cytotoxicity against different cancer cells, also at low molecular concentrations. Its natural occurrence in food commodities and feed is highly reported world-wide, but few information is available about its stability in the human gastro-intestinal tract. The present work evaluates the catabolic fate of enniatin B upon in vitro simulated digestion and colonic fermentation. LC-MS target and untargeted analysis have been performed to quantify the extent of enniatin B degradation and the formation of catabolic products. The results obtained showed significant degradation of enniatin B (degradation rate 79 ± 5%) along the gastrointestinal tract and further degradation of residual enniatin B was observed during colonic fermentation after 24 h of incubation. Moreover, 5 catabolic metabolites of enniatin B were putatively identified after gastrointestinal digestion resulting from the oxidation and opening of the depsipeptide ring. As a final step, the pharmacokinetic properties of enniatin B degradation products were tested in silico revealing that some of them may be adsorbed at the gastrointestinal level more than the parent compound. Additionally, the smaller degradation products showed moderate blood-brain-barrier crossing. Alveolar osteitis is a complication that can occur after tooth extraction, whereby exposed bone results in severe throbbing pain for the patient and can be prone to infection. The current treatment options are widely regarded as sub-optimal. The aim of this project was to investigate in vitro the plausibility of a dual-action monolithic drug-loaded thermosensitive hydrogel that undergoes thermal gelation within the tooth socket and releases both anaesthetic and antimicrobial agents. Hydrogels containing different levels of lidocaine HCl and metronidazole were prepared based upon Carbopol 934P NF and Pluronic F-127 blends. Membrane-less drug release was determined from the set hydrogels into phosphate buffered saline (PBS) at 37 °C as a function of time, following analysis by HPLC. Gelation characteristics and hydrogel dissolution characteristics were also determined. At 23.38% Pluronic F-127, sol-gel transition commenced at 23 °C and gelation was completely at 37 °C (physiological temperature). Setting times varied with Pluronic content and there was an inverse relationship between drug release and Pluronic content. Sustained and dose dependent release of both drugs was observed at therapeutically relevant levels over 24 h, via a combination of diffusion, dissolution and surface erosion processes. Based on the amounts of drugs released, it was determined that hydrogels containing up to 0.5% lidocaine and 0.1% metronidazole exhibited low risk of cytotoxicity to primary human gingival fibroblasts. In an in vivo scenario, the sol-phase formulation would make contact with all inner surfaces of a tooth socket prior to transitioning to monolithic gel-phase and provide sustained release of lidocaine and metronidazole at sub-toxic levels, thereby providing simultaneous pain relief, protection from ingress of debris and pathological bacteria. The members of the BCL-2 associated athanogene (BAG) family participate in the regulation of a variety of interrelated physiological processes, such as autophagy, apoptosis, and protein homeostasis. Under normal circumstances, the six BAG members described in mammals (BAG1-6) principally assist the 70 kDa heat-shock protein (HSP70) in protein folding; however, their role as oncogenes is becoming increasingly evident. Deregulation of the BAG multigene family has been associated with cell transformation, tumor recurrence, and drug resistance. In addition to BAG overexpression, BAG members are also involved in many oncogenic protein-protein interactions (PPIs). As such, either the inhibition of overloading BAGs or of specific BAG-client protein interactions could have paramount therapeutic value. In this review, we will examine the role of each BAG family member in different malignancies, focusing on their modular structure, which enables interaction with a variety of proteins to exert their pro-tumorigenic role. Lastly, critical remarks on the unmet needs for proposing effective BAG inhibitors will be pointed out.
