Viral-Mediated Connexin 26 Expression Combined with Dexamethasone Rescues Hearing in a Conditional Gjb2 Null Mice Model.

GJB2 encodes connexin 26 (Cx26), the most commonly mutated gene causing hereditary non-syndromic hearing loss. Cx26 is mainly expressed in supporting cells (SCs) and fibrocytes in the mammalian cochlea. Gene therapy is currently considered the most promising strategy for eradicating genetic diseases.

ANKRD1 aggravates renal ischaemia‒reperfusion injury via promoting TRIM25-mediated ubiquitination of ACSL3.

Background: Renal ischaemia‒reperfusion injury (IRI) is the primary cause of acute kidney injury (AKI). To date, effective therapies for delaying renal IRI and postponing patient survival remain absent. Ankyrin repeat domain 1 (ANKRD1) has been implicated in some pathophysiologic processes, but its role in renal IRI has not been explored.

Graft survival after percutaneous transluminal renal stenting for transplant renal artery stenosis (TRAS) is worse compared to matched cadaveric grafts without TRAS.

Objectives: Transplant renal artery stenosis (TRAS) is now recognized as a curable disease with a good prognosis if intervention occurs in the early stage. However, the mid-term outcomes of TRAS when treated by percutaneous transluminal angioplasty with stent placement have yet to be fully elucidated. The purpose of this study was to compare mid-term graft and patient survival of TRAS group with a control group.

Validation of the kidney donor profile index (KDPI) for deceased donor kidney transplants in China.

Background: The kidney donor profile index (KDPI) evaluates kidney donor's age, height, weight, ethnicity, cause of death, high blood pressure, diabetes, exposure to hepatitis C and estimated glomerular filtration (eGFR). Kidneys with lower KDPI scores are expected to function longer that those with higher KPDI values. The applicability of KDPI score in Chinese kidney transplant donation has not yet been validated.

A comprehensive survival and prognosis analysis of GPR55 expression in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the most common subtype, accounting for about 90% of all primary liver cancers. The liver is rich in a large number of immune cells, thus forming a special immune microenvironment, which plays a key role in the occurrence and development of hepatocellular carcinoma. Nowadays, tumor immunotherapy has become one of the most promising cancer treatment methods.

Machine Learning Models for Prediction of Severe Pneumonia after Kidney Transplantation: A Single-Center Retrospective Study.

Background: The objective of this study was to formulate and validate a prognostic model for postoperative severe pneumonia (SPCP) in kidney transplant recipients utilizing machine learning algorithms, and to compare the performance of various models.

Methods: Clinical manifestations and laboratory test results upon admission were gathered as variables for 88 patients who experienced PCP following kidney transplantation. The most discriminative variables were identified, and subsequently, Support Vector Machine (SVM), Logistic Regression (LR), Random Forest (RF), K-Nearest Neighbor (KNN), Light Gradient Boosting Machine (LGBM), and eXtreme Gradient Boosting (XGB) models were constructed.

Risk factors for BK virus infection in DCD donor kidney transplant recipients.

Background: BK virus infection after kidney transplantation can negatively impact the prognosis of patients. However, current risk factor analyses primarily focus on BK virus nephropathy, while BK viruria and BK viruria progressing to BK viremia receive less attention. This study aims to analyze the risk factors associated with BK viruria and BK viruria progressing to BK viremia in recipients of donation after cardiac death (DCD), with the goal of facilitating early intervention.

Ubiquitin-specific protease 29 attenuates hepatic ischemia-reperfusion injury by mediating TGF-β-activated kinase 1 deubiquitination.

Background And Aims: In the course of clinical practice, hepatic ischemia/reperfusion (I/R) injury is a prevalent pathophysiological event and is caused by a combination of complex factors that involve multiple signaling pathways such as MAPK and NF-κB. USP29 is a deubiquitinating enzyme important during the development of tumors, neurological diseases, and viral immunity. However, it is unknown how USP29 contributes to hepatic I/R injury.

MAPK Signaling Pathways in Hepatic Ischemia/Reperfusion Injury.

The mitogen-activated protein kinase signaling pathway can be activated by a variety of growth factors, cytokines, and hormones, and mediates numerous intracellular signals related to cellular activities, including cell proliferation, motility, and differentiation. It has been widely studied in the occurrence and development of inflammation and tumor. Hepatic ischemia-reperfusion injury (HIRI) is a common pathophysiological phenomenon that occurs in surgical procedures such as lobectomy and liver transplantation, which is characterized by severe inflammatory reaction after ischemia and reperfusion.

A case report of two Chinese monozygotic twins with NPHP1 gene-associated nephronophthisis undergoing kidney transplantation from a related living-donor.

Background: Nephronophthisis (NPHP) is an autosomal recessive cystic kidney disease and the most common hereditary disease leading to end-stage renal disease in children and adolescents. The NPHP1 gene was the first NPHP gene to be discovered. Pathogenic variation of the NPHP1 gene can cause juvenile renal wasting disease type 1.

Meta-analysis of echinocandins combined with trimethoprim-sulfamethoxazole for treatment of Pneumocystis pneumonia.

Echinocandins form a new drug class for the treatment of Pneumocystis pneumonia (PCP), but their efficacies have not been confirmed. The objective of this study was to review the all-cause mortality and efficacy of echinocandins combined with trimethoprim/sulfamethoxazole (TMP/SMZ) for the treatment of PCP. A meta-analysis of retrospective case-control studies of echinocandins combined with TMP/SMZ or TMP/SMZ alone for treating adult PCP was performed.

N-acetylgalactosaminyltransferase-4 protects against hepatic ischemia/reperfusion injury by blocking apoptosis signal-regulating kinase 1 N-terminal dimerization.

Background And Aims: Ischemia-reperfusion (I/R) injury is an inevitable complication of liver transplantation (LT) and compromises its prognosis. Glycosyltransferases have been recognized as promising targets for disease therapy, but their roles remain open for study in hepatic I/R (HIR) injury. Here, we aim to demonstrate the exact function and molecular mechanism of a glycosyltransferase, N-acetylgalactosaminyltransferase-4 (GALNT4), in HIR injury.

Physiological function and regulatory signal of intestinal type 3 innate lymphoid cell(s).

Of the three groups of innate lymphoid cells, the type 3 innate lymphoid cell(s) (ILC3) include the subgroup of enteric ILC3 that participates in many physiological functions of the organism, such as promoting the repair of damaged mucosa, maintaining the homeostasis of gut symbiotic microorganisms, and presenting specific antigens. ILC3 also includes splenic and decidual ILC3. Like other physiological processes in the organism, enteric ILC3 functions are precisely regulated at the endogenous and exogenous levels.
