Trehalose enhances macrophage autophagy to promote myelin debris clearance after spinal cord injury.
Cell Biosci
January 2025
Department of Orthopaedics, The Second Affiliated Hospital of Anhui Medical University, Hefei, 230601, China.
Background: Myelin-laden foamy macrophages accumulate extensively in the lesion epicenter, exhibiting characteristics of autophagolysosomal dysfunction, which leads to prolonged inflammatory responses after spinal cord injury (SCI). Trehalose, known for its neuroprotective properties as an autophagy inducer, has yet to be fully explored for its potential to mitigate foamy macrophage formation and exert therapeutic effects in the context of SCI.
Results: We observed that trehalose significantly enhances macrophage phagocytosis and clearance of myelin in a dose-dependent manner in vitro.
Patient-derived Organoids and Xenografts Uncover Therapeutic Vulnerabilities in Colorectal Signet Ring Cell Carcinomas.
Clin Cancer Res
January 2025
ACTREC, Tata Memorial Centre, Navi Mumbai, Maharashtra, India.
Purpose: Identifying therapeutic targets for Signet Ring Cell Carcinoma (SRCC) of the colon and rectum is a clinical challenge due to the lack of Patient-Derived Organoids (PDO) or Xenografts (PDX). We present a robust method to establish PDO and PDX models to answer address this unmet need. We demonstrate that these models identify novel therapeutic strategies targeting therapy resistance and peritoneal metastasis.

Background: Hydroxychloroquine is recommended for all patients with systemic lupus erythematosus (SLE) because of its efficacy and safety. Previous studies of antimalarial toxicity under non-experimental conditions have often grouped hydroxychloroquine and chloroquine. This study focuses on the long-term toxicity of antimalarial drugs in SLE patients at a single reference centre.

Lysine acetyltransferase 2B (KAT2B) plays a crucial role in epigenetic regulation and tumor pathogenesis. Our study investigates KAT2B's function in epithelial ovarian cancer (EOC) using in vivo and in vitro methods. Immunohistochemistry showed the KAT2B expression in EOC tissues.

In gastric cancer, the relationship between human epidermal growth factor receptor 2 (HER2), the cyclic GMP-AMP synthase-stimulator of the interferon genes (cGAS-STING) pathway, and autophagy remains unclear. This study examines whether HER2 regulates autophagy in gastric cancer cells via the cGAS-STING signaling pathway, influencing key processes such as cell proliferation and migration. Understanding this relationship could uncover new molecular targets for diagnosis and treatment.
