Article Abstract
This review summarizes recent findings on the role of M2 tumor-associated macrophages (TAMs) and their exosome-derived non-coding RNAs (ncRNAs) in cancer cell resistance to therapeutics. M2 TAMs promote angiogenesis, suppress immune responses, and facilitate metastasis, thereby creating a tumor-supporting microenvironment. A range of antitumor drugs, including 5-FU, cisplatin, and gemcitabine, are mediated by M2 exosomes, each with distinct mechanisms of action. M2 exosomes transfer drug resistance capabilities via extracellular vesicles, especially exosomes containing miRNAs, lncRNAs, and circRNAs. These exosome mediate the development of tumor drug resistance by regulating signaling pathways such as PI3K/AKT, MAPK/ERK, Wnt/β-catenin M2 exosomes can regulate cellular responses by delivering bioactive molecules, including proteins, lipids, and ncRNA, which can also modulate cellular reactions to ionizing radiation, ultraviolet light, and chemotherapeutic agents. Targeting M2 TAMs and their exosome-mediated ncRNAs may offer new strategies to overcome drug resistance in cancer.

Statins in Acute Ischemic Stroke: Mechanisms, Resistance, and Precision Strategies for Neurovascular and Cognitive Protection.

Acute ischemic stroke (AIS) remains a leading cause of mortality and long-term disability globally, with survivors at high risk of recurrent stroke, cardiovascular events, and post-stroke dementia. Statins, while widely used for their lipid-lowering effects, also possess pleiotropic properties, including anti-inflammatory, endothelial-stabilizing, and neuroprotective actions, which may offer added benefit in AIS management. This article synthesizes emerging evidence on statins' dual mechanisms of action and evaluates their role in reducing recurrence, improving survival, and mitigating cognitive decline.

This study evaluated how dietary black seed oil (Nigella sativa L.) against the diazinon waterborne toxicity on Nile tilapia (Oreochromis niloticus), focusing on growth performance, hematological and biochemical parameters as well as oxidative stress markers and histological changes. A 40-day feeding trial was carried out using four experimental groups: Group 1 (control group), Group 2 (N.

Background: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality worldwide. The tumor microenvironment (TME), particularly the interactions between endothelial cells and cancer-associated fibroblasts (CAFs), plays a pivotal role in promoting tumor growth, angiogenesis, oxidative stress, and therapy resistance. The HUVEC-fibroblast co-culture model closely mimics stromal-endothelial interactions observed in CRC, enabling mechanistic insights not achievable in monocultures.

Purpose: To evaluate the impact of MRP inhibition by MK571 on prostate hypercontractility in diet-induced obesity, based on the hypothesis that this intervention enhances intracellular cAMP and cGMP signaling.
Methods: Adult C57BL/6 mice were divided into three groups: (i) lean, (ii) obese, and (iii) obese + MK571 (5 mg/kg/day, 14 days). The prostate was isolated for immunohistochemistry, biochemistry and functional assays.
Efficacy and activity of gepotidacin against bacterial uropathogens, including drug-resistant phenotypes, in females with uncomplicated urinary tract infections: results from two global, pivotal, phase 3 trials (EAGLE-2 and EAGLE-3).

Two recent Phase 3 trials demonstrated the efficacy of gepotidacin compared with nitrofurantoin to treat uncomplicated urinary tract infections (uUTIs) in females. Pretreatment urine specimens were obtained from all participants. Based on pooled trial data (treatment groups combined), central laboratory culture results identified 1,421 (45%) participants with ≥1 baseline qualifying (≥10 CFU/mL) uropathogen (i.
