cGAS suppresses β-cell proliferation by a STING-independent but CEBPβ-dependent mechanism.

Aims/hypothesis: cGAS (cyclic GMP-AMP synthase) has been implicated in various cellular processes, but its role in β-cell proliferation and diabetes is not fully understood. This study investigates the impact of cGAS on β-cell proliferation, particularly in the context of diabetes.

Methods: Utilizing mouse models, including cGAS and STING (stimulator of interferon genes) knockout mice, we explored the role of cGAS in β-cell function.

Circulating Galectin-3 levels and Diabetic Nephropathy: a systematic review and meta-analysis.

Aims: Changes of serum galectin-3 (Gal-3) is associated with the pathogenesis of diabetic nephropathy (DN). However, current literature indicates that the given results remain debatable and inconsistent. Hence, the aim of this present meta-analysis was to focus on the predictive role of serum Gal-3 in patients with DN.

Excellent clinical outcomes of renal transplant from pediatric deceased donors with acute kidney injury.

Background: The use of kidneys from deceased donors with acute kidney injury (AKI) to expand the donor pool is an ongoing trend. Prior research on the utilization of AKI donor kidneys, especially from pediatric AKI donors, was limited and has been subject to small sample sizes. In this study, we aimed to evaluate the safety and effectiveness of early post-transplantation outcomes in pediatric deceased donors with AKI.

Fibroblast growth factor 21 may be a strong biomarker for renal outcomes: a meta-analysis.

Background: Fibroblast growth factor 21 (FGF21) is deemed to play an important role in kidney outcomes, while the association between FGF21 and various kidney diseases remains largely unclear and inconsistent. Therefore, we conducted this meta-analysis to find out the role of FGF21 in various renal diseases.

Methods: The outcome indicator of our study was assessed by the pooled standard mean difference (SMD) with 95% confidence intervals (CIs) which were calculated by random-effect model analysis.

The adipocyte-enriched secretory protein tetranectin exacerbates type 2 diabetes by inhibiting insulin secretion from β cells.

Pancreatic β cell failure is a hallmark of diabetes. However, the causes of β cell failure remain incomplete. Here, we report the identification of tetranectin (TN), an adipose tissue-enriched secretory molecule, as a negative regulator of insulin secretion in β cells in diabetes.

Utilization of HCV Viremic Kidneys with Genotyping/Subtyping-Free Sofosbuvir/Velpatasvir Treatment Strategy: Experience from China.

Background: Owing to the advent of pangenotypic direct-acting antiviral agents (DAAs) for hepatitis C virus (HCV) treatment, utilization of HCV-infected deceased donor kidneys with simplified genotyping/subtyping-free sofosbuvir/velpatasvir (SOF/VEL) treatment strategy is now becoming a promising strategy for expanding the organ donor pool.

Methods: This retrospective, comparative, single-center study included HCV viremic donor kidneys that were transplanted to 9 HCV-positive (HCV Ab-positive) recipients (D+/R+ group) and 14 HCV-negative recipients (D+/R- group) from May 2018 to January 2021. Both groups received prophylaxis with SOF/VEL treatment within 1-week posttransplant devoid of HCV genotyping/subtyping.

GRB10 regulates β-cell mass by inhibiting β-cell proliferation and stimulating β-cell dedifferentiation.

Decreased functional β-cell mass is the hallmark of diabetes, but the cause of this metabolic defect remains elusive. Here, we show that the levels of the growth factor receptor-bound protein 10 (GRB10), a negative regulator of insulin and mTORC1 signaling, are markedly induced in islets of diabetic mice and high glucose-treated insulinoma cell line INS-1 cells. β-cell-specific knockout of Grb10 in mice increased β-cell mass and improved β-cell function.

Comparison of Outcomes of Kidney Transplantation From Extremely Low Body Weight ≤5kg Larger Body Weight Pediatric Donors.

Background: Kidney transplantation from donors who weigh ≤5 kg is performed at only a few transplant centers owing to the high complication and low graft survival rates associated with this approach.

Methods: We retrospectively compared the results of kidney transplantation at our center between January 2015 and December 2019 based on the following pediatric donor criteria: donor body weight ≤5 kg (n=32), 5 kg< donor weight ≤20 kg (n=143), and donor weight >20 kg (n=110). We also perform subgroup analysis of kidney transplantation outcomes from ≤5 kg donors, using conventional (dual separate and classic en-bloc KTx)/novel (en-bloc KTx with outflow tract) surgical methods and allocating to adult/pediatric recipients.

Rheb1 promotes glucose-stimulated insulin secretion in human and mouse β-cells by upregulating GLUT expression.

Reduced β-cell mass and impaired β-cell function are primary causes of all types of diabetes. However, the intrinsic molecular mechanism that regulates β-cell growth and function remains elusive. Here, we demonstrate that the small GTPase Rheb1 is a critical regulator of glucose-stimulated insulin secretion (GSIS) in β-cells.

ATG3, a Target of miR-431-5p, Promotes Proliferation and Invasion of Colon Cancer via Promoting Autophagy.

Background: Studies have indicated that ATG3 could mediate the effects of other tumor-related regulators in carcinogenesis. However, the expression, role, and mechanism of ATG3 itself in cancers are rarely revealed. Thus, we explored the expression, function, and mechanism of ATG3 in colon cancer.

miR-181a Upregulation Promotes Radioresistance of Nasopharyngeal Carcinoma by Targeting RKIP.

Background: Radioresistance is the leading cause of treatment failure for nasopharyngeal carcinoma (NPC). Therefore, screening the critical regulators in radioresistance and revealing the underlying mechanisms is imperative for improvement of therapeutical efficacy in NPC.

Materials And Methods: Our previous study has proved that miR-181a may serve as a pro-radioresistant miRNA.

CAV3.1 knockdown suppresses cell proliferation, migration and invasion of prostate cancer cells by inhibiting AKT.

Background: Aberrant expression of CAV3.1, one of T-type Ca channels, is reported to exert important functions in pathological processes, including carcinogenesis. However, its expression pattern and function in prostate cancer (PCa) remains unclear.

[Phloroglucinol combined with parecoxib for cystospasm after transurethral resection of the prostate].

Objective: To evaluate the effect and safety of phloroglucinol combined with parecoxib on cystospasm after transurethral resection of the prostate (TURP).

Methods: We conducted a prospective randomized case-control study on 98 patients treated by TURP. After operation, the patients were randomly assigned to a treatment (n=50) and a control group (n=48), the former treated by intravenous injection of 80 mg phloroglucinol qd plus 40 mg parecoxib bid while the latter given 80 mg phloroglucinol only, both for 3 successive days.

[Safety and effectiveness of GreenLight 120-W laser photoselective vaporization of the prostate for benign prostatic hyperplasia: A meta-analysis].

Objective: To evaluate the safety and effectiveness of GreenLight 120-W laser photoselective vaporization of the prostate (PVP) versus transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).

Methods: We searched PubMed, Medline, Embase, Cochrane Library, Wanfang, CNKI, and VIP for randomized control trials and their references addressing 120-W PVP versus TURP in the treatment of BPH. Based on the inclusion and exclusion criteria, two reviewers independently accomplished the screening, quality assessment, and data extraction of the identified studies and performed meta-analyses using RevMan 5.

Down-regulation of HMGB1 expression by shRNA constructs inhibits the bioactivity of urothelial carcinoma cell lines via the NF-κB pathway.

The high mobility group box 1 (HMGB1), which is a highly conserved and evolutionarily non-histone nuclear protein, has been shown to associate with a variety of biological important processes, such as transcription, DNA repair, differentiation, and extracellular signalling. High HMGB1 expression has been reported in many cancers, such as prostate, kidney, ovarian, and gastric cancer. However, there have been few studies of the function of HMGB1 in the malignant biological behaviour of bladder urothelial carcinoma (BUC), and the potential mechanism of HMGB1 in the pathogenesis of BUC remains unclear.
