e., CD45/ CD19/ CD14/ CD34-negative cells). In-vitro expanded MSCs from primary osteoarthritis patients showed reduced osteogenic and chondrogenic potential in comparison with dysplasia patients. There were no differences in clonogenicity, growth kinetics, senescence, adipogenic potential, and immunophenotype between these groups. Gene expression profiling showed well-known marker of bone marrow MSCs, the leptin receptor, to be significantly lower for primary osteoarthritis patients. Our study shows that the pathology of primary osteoarthritis is accompanied by bone MSC exhaustion, while biomechanical dysfunction associated with hip dysplasia can induce secondary osteoarthritis without this MSC impairment. Our study suggests that subchondral bone MSC exhaustion is implicated in the pathology of primary osteoarthritis.IRE1α endonuclease is a key regulator of endoplasmic reticulum (ER) stress that controls cell survival/apoptosis in cancers. Inhibition of IRE1α endonuclease leads to decreased splice XBP1 which decreases cell proliferation and increases cell death in cancer cells. Epigenetic inhibitor Therefore, this study investigated the effects and mechanism of STF-083010 (an IRE1α inhibitor) on the cell growth/apoptosis of ovarian malignant cells via the XBP1-CHOP-Bim pathway following the induction of ER stress (ERS). ERS in OVCAR3 and SKOV3 cells was measured using Thioflavin T staining. The expression of ER stress response genes was evaluated by QRT-PCR. The levels of XBP1(s), PERK, phospho-PERK, p-PP2A, ATF4, BIP/GRP78, CHOP, and Bim proteins were evaluated using western blotting. Cell viability and apoptosis in STF-083010 and Tunicamycin (Tm) co-treated cells were assessed using BrdU, MTT, Annexin V-FITC/PI staining, and caspases-12 and -3 activity assays. The results showed increased XBP1, CHOP, and ATF-4 mRNA expression levels as well as high protein aggregation in STF-083010 and Tm co-treated cells. The IRE1α inhibitor down-regulated sXBP1 and BIP proteins, while XBP-1, p-PERK, ATF-4, CHOP, and Bim proteins were up-regulated. STF-083010 reduced cell proliferation and induced apoptosis through the activation of caspases-12 and -3 and Bax/Bcl-2 protein expression. In summary, the present data revealed the effects of STF-083010 in ER stress and apoptosis as well as signaling via XBP1/CHOP/Bim mediators. Thus, STF-083010 is proposed as a new target for the control of ERS in ovarian cancer cells.CUDC-907 is a novel dual-acting inhibitor of phosphoinositide 3-kinase (PI3K) and histone deacetylase (HDAC). In this study, we aimed to explore the anticancer effects of CUDC-907 on human breast cancer cells. Our results showed that CUDC-907 effectively inhibited breast cancer cell proliferation. Flow cytometry analysis revealed that CUDC-907 induced cell cycle arrest and apoptosis in breast cancer cells. The combined treatment of CUDC-907 and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) resulted in a marked increase in apoptosis and cleavage of caspase-8, -9 and poly (ADP-ribose) polymerase (PARP) in breast cancer cells. CUDC-907 enhanced expressions of death receptor 5 (DR5), reduced the levels of anti-apoptotic molecules XIAP, Bcl-2 and Bcl-xL. Knockdown of DR5 abrogated apoptosis induced by the combination of CUDC-907 and TRAIL in breast cancer cells. CUDC-907 increased the phosphorylation of JNK and p38 MAPK. JNK inhibitor pretreatment attenuated CUDC-907-induced upregulation of DR5. In summary, CUDC-907 shows potent cytotoxicity against breast cancer cells and facilitates TRAIL-mediated apoptosis through DR5 upregulation. The combination of CUDC-907 and TRAIL may be a promising therapeutic approach in the treatment of breast cancer.Acute elevations in blood pressure (BP), usually defined as ≥ 180/110 mmHg, may present with highly heterogeneous profiles ranging from absence of symptoms to life-threatening target organ damage. In most recent years the diagnostic approach and the treatment of hypertension have gained interest by patients and physicians. The GEAR project (Gestione delle Emergenze e urgenze in ARea critica, management of hypertensive emergencies and hypertensive urgencies in the emergency setting) was proposed by the group of Young Investigators of the Italian Society of Hypertension as a survey aimed to evaluate the awareness, diagnosis and treatment of hypertensive emergencies and urgencies in Italy.Bariatric surgery is currently the most effective weight loss treatment of severe obesity and its associated comorbidities and is being increasingly used to treat children and adolescents with severe obesity, including those with Type 2 Diabetes (T2D). This review focuses on the conventional management of T2D in children and adolescents, comparison of various types of bariatric surgeries, effect of bariatric surgery on gastrointestinal physiology and metabolism, current literature on the use of bariatric surgery to treat youth with severe obesity and T2D, and the potential complications of bariatric surgery in this population.This chapter gives an overview of present knowledge and clinical aspects of antidiabetic drugs according to the recently available research evidence and clinical expertise.Many agents are acting on eight groups of pathophysiological mechanisms, which is commonly called as "Ominous Octet" by DeFronzo. The muscle, liver and β-cell, the fat cell, gastrointestinal tract, α-cell, kidney, and brain play essential roles in the development of glucose intolerance in type 2 diabetic individuals (Defronzo, Diabetes 58773-795, 2009).A treatment paradigm shift is seen in the initiation of anti-hyperglycemic agents from old friends (meglitinides or sulphonylürea) to newer agents effecting on GLP-1 RA or SGLT-2 inhibitors. It is mostly about the other protective positive effects of these agents for kidney, heart, etc. Although there are concerns for the long term safety profiles; they are used widely around the World. The delivery of patient-centered care, facilitating medication adherence, the importance of weight loss in obese patients, the importance of co-morbid conditions are the mainstays of selecting the optimal agent.
