LDL-Cholesterol Lowering Agents (Statins and PCSK9 Inhibitors) and the Risk of Intracerebral Hemorrhage: A Network Meta-Analysis.

J Stroke Cerebrovasc Dis

January 2025

Department of Neurology, Chongqing University Three Gorges Hospital, Wanzhou, Chongqing, 400016, China; School of Medicine, Chongqing University, Chongqing, 404010, China. Electronic address:

Background And Purpose: Statin therapy reduces the risk of ischemic stroke; however, certain studies have observed an increased incidence of intracerebral hemorrhage (ICH). Moreover, proprotein convertase subtilisin/kexin type 9(PCSK-9) inhibitors have emerged as a powerful class of lipid-lowering medications, potentially with a lower propensity for causing hemorrhagic events. To investigate this matter further, we conducted a network meta-analysis of randomized controlled trials (RCTs) involving statins and PCSK-9 inhibitors that reported occurrences of ICH.

Introduction: Osimertinib is the first-line treatment for patients with non-small cell lung cancer (NSCLC) who have EGFR mutations and favorable performance status (PS). Despite increasing clinical data on osimertinib, evidence in patients with an impaired PS remains limited. Therefore, a multicenter phase II trial (OPEN/TORG2040) was conducted to evaluate the efficacy and safety of first-line osimertinib for patients with EGFR mutation-positive NSCLC and poor PS.

January 2025

Institute of Human Genetics, Jena University Hospital, Jena, Germany; Urology and Nephrology Research Center, Research Institute for Urology and Nephrology, Shahid Beheshti University of Medical Sciences, Tehran, Iran. Electronic address:

Circular RNAs (circRNAs) have emerged as critical regulators in cancer biology, contributing to various cancer hallmarks, including cell proliferation, apoptosis, metastasis, and drug resistance. Defined by their covalently closed loop structure, circRNAs possess unique characteristics like high stability, abundance, and tissue-specific expression. These non-coding RNAs function through mechanisms such as miRNA sponging, interactions with RNA-binding proteins (RBPs), and modulating transcription and splicing.

A Guide to Pathophysiology, Signaling Pathways, and Preclinical Models of Liver Fibrosis.

Mol Cell Endocrinol

January 2025

Department of Pharmaceutical Sciences, College of Pharmacy and Health Sciences, St. John's University, Queens, NY,11439, USA. Electronic address:

Liver fibrosis is potentially a reversible form of liver disease that evolved from the early stage of liver scarring as a consequence of chronic liver injuries. Recurrent injuries in the liver without any appropriate medication cause the injuries to get intense and deeper, which gradually leads to the progression of irreversible cirrhosis or carcinoma. Unfortunately, there are no approved treatment strategies for reversing hepatic fibrosis, making it one of the significant risk factors for developing advanced liver disorders and liver disease-associated mortality.

Background: Either dual antiplatelet therapy or oral anticoagulation in combination with aspirin represent recommended treatment regimens following left atrial appendage closure (LAAC). As the majority of patients receiving LAAC have high bleeding risk, less aggressive antithrombotic treatments are needed, such as single antiplatelet therapy.

Objectives: To compare both ischemic and bleeding outcomes in patients receiving single (SAPT) or dual antiplatelet therapy (DAPT) after successful LAAC.

Immunity

December 2024

Division of Oncogenomics, Oncode institute, the Netherlands Cancer Institute, Amsterdam, the Netherlands; Erasmus MC, Department of Genetics, Rotterdam University, Rotterdam, the Netherlands. Electronic address:

Prolonged exposure to interferon-gamma (IFNγ) and the associated increased expression of the enzyme indoleamine 2,3-dioxygenase 1 (IDO1) create an intracellular shortage of tryptophan in the cancer cells, which stimulates ribosomal frameshifting and tryptophan to phenylalanine (W>F) codon reassignments during protein synthesis. Here, we investigated whether such neoepitopes can be useful targets of adoptive T cell therapy. Immunopeptidomic analyses uncovered hundreds of W>F neoepitopes mainly presented by the HLA-A24:02 allele.

Proteolysis targeting chimeras (PROTACs) are bifunctional molecules that induce selective protein degradation by linking an E3 ubiquitin ligase enzyme to a target protein. This approach allows scope for targeting "undruggable" proteins, and several PROTACs have reached the stage of clinical candidates. However, the roles of cellular transmembrane transporters in PROTAC uptake and efflux remain underexplored.

Electronic address:

Tripartite motif-containing proteins (TRIMs), comprising the greatest subfamily of E3 ubiquitin ligases with approximately 80 members of this family, are widely distributed in mammalian cells. TRIMs actively participate in ubiquitination of target proteins, a type of post-translational modification associated with protein degradation and other functions. Tripartite motif-containing protein 29 (TRIM29), a member of the TRIM family, differs from other members of this family in that it lacks the RING finger structural domain containing cysteine and histidine residues that mediates DNA binding, protein-protein interactions, and ubiquitin ligase, at its N-terminus.

Background: Neoadjuvant chemotherapy, particularly the use of platinum-based compounds and taxanes, is pivotal in the treatment of epithelial-derived tumors, such as cervical cancer and esophageal squamous cell carcinoma (ESCC); however, resistance remains a significant challenge. Utilizing Mendelian randomization (MR) with pharmacogenomics offers a novel approach to understanding the genetic underpinnings of drug responses, thereby aiding in personalized treatment.

Methods: Single-cell RNA sequencing (scRNA-seq) analysis revealed a shared cellular subpopulation of CD8 + T effector memory (CD8 + TEM) cells that are pivotal in mediating chemotherapy resistance in ESCC and cervical cancer.

Ursolic acid (3-hydroxy-urs-12-ene-28-oic acid, UA) is a pentacyclic triterpene present in numerous plants, fruits and herbs and exhibits various pharmacological effects. However, UA has limited clinical applicability since it is classified as BCS class IV molecule, characterized by low solubility, low oral bioavailability and low permeability. In the present study, UA was isolated from the biomass marc of Lavandula angustifolia and was structurally modified by an induction of indole ring at the C-3 position and amide group at the C-17 position with the aim to enhance its pharmacological potential.
