The elevated or reduced salt tolerance of atpprt1 and AtPPRT1 overexpressing lines was confirmed by the changes in chlorophyll content and 3,3'-Diaminobenzidine (DAB) staining. The above data suggest that AtPPRT1 has a negative effect on salt tolerance in Arabidopsis seedlings.MAFG antisense 1 (MAFG-AS1) is recently identified as a novel lncRNA and serves as a tumor promoter in several types of human tumor. However, no prior study has been performed to evaluate the role of MAFG-AS1 in gastric cancer. In our study, we found MAFG-AS1 expression was increased in gastric cancer tissue samples compared with normal gastric mucosa tissue samples, and associated with poor overall survival in gastric cancer patients at The Cancer Genome Atlas database. Furthermore, we confirmed the clinical and prognostic significance of MAFG-AS1 in gastric cancer. We found gastric cancer tissues and cell lines had remarkably increased MAFG-AS1 expression in comparison to normal gastric mucosa tissues and normal human gastric epithelial cell line, and high MAFG-AS1 expression was positively associated with diffuse type, advanced clinical stage, extensive depth of invasion, more lymph node metastasis, and present distant metastasis in gastric cancer patients. Moreover, high MAFG-AS1 expression acted as one of the independent poor prognostic factors for overall survival in gastric cancer patients. The loss-of-function study showed knocking down MAFG-AS1 expression inhibited gastric cancer cell proliferation, migration and invasion in vitro. In conclusion, MAFG-AS1 is probable to be a valuable prognostic biomarker, and a novel potential target for gastric cancer.Opportunistic bacterial infections amongst HIV-infected individuals contribute significantly to HIV-associated mortality. The role of HIV-mediated modulation of innate mechanisms like autophagy in promoting opportunistic infections, however, remains obscure. Here we show, HIV reactivation in or infection of macrophages inhibits autophagy and helps the survival of pathogenic Mycobacterium tuberculosis (Mtb) and nonpathogenic non-tuberculous mycobacterial strains (NTMs). The HIV-mediated impairment of xenophagy flux facilitated bacterial survival. Activation of autophagy by trehalose could induce xenophagy flux and kill intracellular Mtb or NTMs either during single or co-infections. Trehalose, we delineate, activates PIKFYVE leading to TFEB nuclear translocation in MCOLN1-dependent manner to induce autophagy. Remarkably, trehalose significantly reduced HIV-p24 levels in ex-vivo-infected PBMCs or PBMCs from treatment-naive HIV patients and also controlled mycobacterial survival within Mtb-infected animals.

Herpesviruses have developed strategies to evade autophagic degradation and to manipulate autophagy of the host cells to their benefit. click here Here we addressed the role of macroautophagy/autophagy in human cytomegalovirus replication and for particle morphogenesis. We found that proteins of the autophagy machinery localize to cytoplasmic viral assembly compartments and enveloped virions in the cytoplasm. Surprisingly, the autophagy receptor SQSTM1/p62 was also found to colocalize with HCMV capsids in the nucleus of infected cells. This finding indicates that the autophagy machinery interacts with HCMV already at the early nuclear stages of particle morphogenesis. The membrane-bound form of LC3 and several autophagy receptors were packaged into extracellular HCMV virions. This suggested that autophagic membranes were included during secondary envelopment of HCMV virions. To further address the importance l repeat short; UL unique long; US unique short.Platelet lifespan is regulated by intrinsic apoptosis. Platelet apoptosis can be triggered by BH3 mimetics that inhibit the pro-survival Bcl-2 family protein, Bcl-xL. Here, we investigated several small molecules that are reported to act as BH3 mimetics and compared their effects to the well-established BH3 mimetic, ABT-737. Platelet phosphatidylserine (PS) exposure was determined by flow cytometry. Changes in cytosolic Ca2+ signaling were detected using Cal-520. Plasma membrane integrity was determined by calcein leakage. The roles of caspases and calpain in these processes were determined using Q-VD-OPh and calpeptin, respectively. As previously reported, ABT-737 triggered PS exposure in a caspase-dependent manner and calcein loss in a caspase and calpain-dependent manner. In contrast, AT-101 and sabutoclax triggered PS exposure independently of caspases. HA14-1 also triggered PS exposure in a caspase-independent but calpain-dependent manner. There were also significant differences in the pattern and protease-dependency of cytosolic Ca2+ signaling in response to these drugs compared to ABT-737. Since there are clear differences between the action of ABT-737 and the other putative BH3 mimetics investigated here, AT-101, HA14-1 and sabutoclax cannot be considered as acting as BH3 mimetics in platelets. Furthermore, the platelet death caused by these drugs is likely to be distinct from apoptosis.BACKGROUND Clozapine is more effective than other atypical antipsychotics for treatment resistant schizophrenia, but has serious side effects. Clozapine has an estimated cumulative seizure risk of 10% in patients treated for 3.8 years. Bupropion can also induce seizures and its estimated risk is 0.4% at recommended doses. While some risk factors for seizures are known, much remains unknown about predicting seizure risk. CASES We present 2 cases of seizures in patients treated with clozapine and bupropion without a seizure history. In the first case, a patient with schizoaffective disorder treated with dual antipsychotic therapy had a witnessed generalized tonic-clonic seizure. With the exception of bupropion/naltrexone which was started 2.5 months prior for weight loss, she had not had any recent medication changes. In the second case, a patient with schizoaffective disorder was treated with clozapine and was prescribed bupropion SR for smoking cessation for an extended duration. He had cut back on cigarette use in the 2 months prior to reporting "spells.
