SET domain-containing 2 (SETD2), the primary methyltransferase for histone 3 lysine-36 trimethylation (H3K36me3) in mammals, is associated with many hematopoietic diseases when mutated. Previous works have emphasized its role in maintaining adult hematopoietic stem cells or tumorigenesis, however, whether and how SETD2 regulates erythropoiesis during embryonic development is relatively unexplored. In this study, using a conditional SETD2 knockout (KO) mouse model, we reveal that SETD2 plays an essential role in fetal erythropoiesis. Loss of Setd2 in hematopoietic cells ablates H3K36me3, and leads to anemia with a significant decrease in erythroid cells in the peripheral blood at E18.5. This is due to impaired erythroblast differentiation in both spleen and liver. We also find increased proportions of nucleated erythrocytes in the blood of Setd2 KO embryos. Lastly, we ascribe embryonic erythropoiesis-related genes Vegfc, Vegfr3, and Prox1, as likely downstream targets of SETD2 regulation. Our study reveals a critical role of SETD2 in fetal erythropoiesis that precedes adult hematopoiesis, and provide unique insights into the defects in erythroid lineages, such as anemia.
Angiotensin II (Ang II), an important component of the renin-angiotensin system (RAS), plays a critical role in the pathogenesis of cardiovascular disorders. In addition, human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) have been considered as a promising platform for studying personalized medicine for heart diseases. However, whether Ang II can induce the apoptosis of hiPSC-CMs is not known.

In this study, we treated hiPSC-CMs with different concentrations of Ang II [0nM (vehicle as a control), 1nM, 10nM, 100nM, 1μM, 10μM, 100μM, and 1mM] for various time periods (24h, 48h, 6 days, and 10 days) and analyzed the viability and apoptosis of hiPSC-CMs.

We found that treatment with 1mM Ang II for 10 days reduced the viability of hiPSC-CMs by 41% (p=2.073E-08) and increased apoptosis by 2.74-fold, compared to the control group (p=6.248E-12). MYOG, which encodes the muscle-specific transcription factor myogenin, was also identified as an apoptosis-suppressor gene in Ang II-treated hiPSC-CMs. Ectopic MYOG expression decreased the apoptosis and increased the viability of Ang II-treated hiPSC-CMs. Zamaporvint Further analysis of the RNA sequencing (RNA-seq) data illustrated that myogenin ameliorated Ang II-induced apoptosis of hiPSC-CMs by downregulating the expression of proinflammatory genes.

Our findings suggest that Ang II induces the apoptosis of hiPSC-CMs and that myogenin attenuates Ang II-induced apoptosis.
Our findings suggest that Ang II induces the apoptosis of hiPSC-CMs and that myogenin attenuates Ang II-induced apoptosis.Autophagy is known to play a critical role in the early stages of embryogenesis including the formation of blastocyst. The existence of p53 protein-deficient mice may identify that p53 is not indispensable for the activation of autophagy in pluripotent cells derived from the inner cell mass of the blastocyst. We utilized a p53-knockout (KO) mouse embryonic stem cell (mESC) line to investigate the contribution of p53 in autophagy. We showed that lack of p53 has no effect on cell pluripotency but significantly hinders the differentiation process induced by retinoic acid. Using MRT68921, we revealed that Ulk1-dependent autophagy is activated in response to serum deprivation despite the deletion of p53 in mESCs. link2 However, under retinoic acid-induced differentiation, the accumulation of autophagosomes and lysosomes is impaired in p53 KO mESCs, indicating a critical role of p53 in the regulation of autophagy upon differentiation.The biogenesis of outer membrane proteins requires the function of β-barrel assembly machinery (BAM), whose function is highly conserved while its composition is variable. The Escherichia coli BAM is composed of five subunits, while Thermus thermophilus seems to contain a single BAM protein, named TtOmp85. To search for the primitive form of a functional BAM, we investigated and compared the function of TtOmp85 and E. coli BAM by use of a reconstitution assay that examines the integration of OmpA and BamA from E. coli and TtoA from T. thermophilus, as well as the translocation of the E. coli Ag43. Our results show that a single TtOmp85 protein can substitute for the collective function of the five subunits constituting E. coli BAM.Transplantation of retinal pigment epithelium (RPE) cells derived from human embryonic stem cells (hESCs) or induced pluripotent stem cells (hiPSCs) hold great promise as a new therapeutic modality for age-related macular degeneration and Stargardt disease. The development of hESC/hiPSC-derived RPE cells as cell-based therapeutic products requires a robust, scalable production for every hiPSC line congruent for patients. However, individual hESC/hiPSC lines show bias in differentiation. Here we report an efficient, robust method that induces RPE cells regardless of the differentiation propensity of the hiPSC lines. Application of the tankyrase inhibitor IWR-1-endo, which potentially inhibits Wnt signaling, promoted retinal differentiation in dissociated hiPSCs under feeder-free, two-dimensional culture conditions. The other tankyrase inhibitor, XAV939, also promoted retinal differentiation. However, Wnt signaling inhibitors, IWP-2 and iCRT3, that target porcupine and β-catenin/TCF, respectively, did not. Further treatment with the GSK3β inhibitor CHIR99021 and FGF receptor inhibitor SU5402 induced hexagonal pigmented cells with phagocytotic ability. Notably, the IWR-1-endo-based differentiation method induced RPE cells even in an hiPSC line that expresses a lower level of the differentiation propensity marker SALL3, which is indicative of resistance to ectoderm differentiation. The present study demonstrated that tankyrase inhibitors cause efficient and robust RPE differentiation, irrespective of the SALL3 expression levels in hiPSC lines. This differentiation method will resolve line-to-line variations of hiPSCs in RPE production and facilitate clinical application and industrialization of RPE cell products for regenerative medicine.Hepatocellular carcinoma (HCC) is the fifth common types of cancer with poor prognosis in the world. Honokiol (HNK), a natural biphenyl compound derived from the magnolia plant, has been reported to exert anticancer effects, but its mechanism has not been elucidated exactly. In the present study, HNK treatment significantly suppressed the migration ability of HepG2 and Hep3B human hepatocellular carcinoma. The treatment reduced the expression levels of the genes associated with cell migration, such as S100A4, MMP-2, MMP-9 and Vimentin. Interestingly, treatment with HNK significantly reduced the expression level of Cyclophilin B (CypB) which stimulates cancer cell migration. However, overexpressed CypB abolished HNK-mediated suppression of cell migration, and reversed the apoptotic effects of HNK. Altogether, we concluded that the suppression of migration activities by HNK was through down-regulated CypB in HCC. These finding suggest that HNK may be a promising candidate for HCC treatment via regulation of CypB.2-aminoethylphosphonatepyruvate aminotransferase (AEPT) is a pyridoxal 5'-phosphate (PLP)-dependent enzyme that mediates the first step in the AEP degradation pathway. It catalyzes the transamination of 2-aminoethylphosphonate (AEP) with pyruvate to phosphonoacetaldehyde and l-alanine respectively. Although the enzyme is widely present in microorganisms, there are few reports on the structure and function of AEPT to date. Here we report the crystal structure of AEPT from Pseudomonas aeruginosa PAO1 (PaAEPT) to 2.35 Å resolution in the absence of the PLP cofactor. PaAEPT crystallizes in space group P21212 with one monomer per asymmetric unit. Analytical ultracentrifugation analysis shows that PaAEPT forms a stable dimer in solution. Our work provides a valuable starting point for further functional and mechanistic studies of the AEP degradation pathway.Cancer is characterized by uncontrolled proliferation resulting from aberrant cell cycle progression. The activation of phosphatidylinositol 3-kinase (PI3K)/AKT signaling, a regulatory pathway for the cell cycle, stabilizes cyclin D1 in the G1 phase by inhibiting the activity of glycogen synthase kinase 3β (GSK3β) via phosphorylation. We previously reported that phospholipase C-related catalytically inactive protein (PRIP), a phosphatidylinositol 4,5-bisphosphate [PI(4,5)P2] binding protein, regulates PI3K/AKT signaling by competitively inhibiting substrate recognition by PI3K. Therefore, in this study, we investigated whether PRIP is involved in cell cycle progression. PRIP silencing in MCF-7 cells, a human breast cancer cell line, demonstrated PI(3,4,5)P3 signals accumulated at the cell periphery compared to that of the control. This suggests that PRIP reduction enhances PI(3,4,5)P3-mediated signaling. Consistently, PRIP silencing in MCF-7 cells exhibited increased phosphorylation of AKT and GSK3β which resulted in cyclin D1 accumulation. In contrast, the exogenous expression of PRIP in MCF-7 cells evidenced stronger downregulation of AKT and GSK3β phosphorylation, reduced accumulation of cyclin D1, and diminished cell proliferation in comparison to control cells. Flow cytometry analysis indicated that MCF-7 cells stably expressing PRIP attenuate cell cycle progression. Importantly, tumor growth of MCF-7 cells stably expressing PRIP was considerably prevented in an in vivo xenograft mouse model. link3 In conclusion, PRIP expression downregulates PI3K/AKT/GSK3β-mediated cell cycle progression and suppresses tumor growth. Therefore, we propose that PRIP is a new therapeutic target for anticancer therapy.SARS-CoV-2 pandemic heavily hit the western healthcare system saturating the hospital beds in wards and clogging the emergency departments. To avoid the collapse of Italian hospitals, office visits to outpatients were limited to emergencies and the general population went in a lockdown state. Physicians had to approach new problems in the management of chronic patients who could not leave their homes. In our experience as epilepsy clinic, the use of telemedicine was of crucial importance for monitoring our patients phone call during lockdown let us monitor the stability of our 38 patients and psychometric parameters and habits that could influence seizures frequency. In particular, we found that in our patients, sleep quality was low resulting in high daily sleepiness and associated high stress levels. Secondly, we found an increase in daily screen hours and an association with daily sleepiness. In conclusion, we report our experience in managing people with epilepsy during the lockdown, underlining the utility of telemedicine as a valid monitoring tool and the necessity of a psychometric and behavioral screening.
In March 2020, the World Health Organization declared the SARS-CoV-2 infection-related coronavirus Disease (COVID-19) a pandemic. During the first and second waves of the pandemic spread, there have been several reports of COVID-19-associated neurological manifestations, including acute seizures and status epilepticus (SE). In this systematic review, we summarized the available data on clinical features, diagnosis, and therapy of COVID-19-related SE.

We performed a systematic search of the literature to identify data on demographics, clinical, neurophysiological, and neuroradiological data of patients with COVID-19-related SE. We used regression models (linear or logistic) with a stepwise forward method to identify features associated with mortality or severity of SE.

Thirty-nine articles were included with a total of 47 cases of SE associated with COVID-19. Age, time between the acute respiratory phase of SARS-CoV-2 infection and SE onset, and hospitalization correlated with a higher SE severity as assessed by quantitative validated scales.
