Article Abstract
Members of the galectin family have been shown to exert several roles in the context of reproduction. They contribute to placentation, maternal immune regulation and facilitate angiogenesis encompassing decidualisation and placenta formation during pregnancy. In the context of neo-vascularisation, galectins have been shown to augment signalling pathways that lead to endothelial cell activation, cell proliferation, migration and tube formation in vitro in addition to angiogenesis in vivo. Angiogenesis during gestation ensures not only proper foetal growth and development, but also maternal health. Consequently, restriction of placental blood flow has major consequences for both foetus and mother, leading to pregnancy diseases. In this review we summarise both the established and the emerging roles of galectin in angiogenesis and discuss the possible implications during healthy and pathological gestation.

Pectin is a structurally diverse, plant-derived polysaccharide primarily obtained from apple pomace and citrus fruits. Its biocompatibility, modifiability, and multiple bioactivities have attracted increasing interest for potential applications in cancer therapy. This review summarizes modification techniques that enhance pectin's physicochemical and biological properties, elucidates its main anticancer mechanisms, and highlights recent advances (2020-2025) in its therapeutic potential.

The mechanisms underlying therapeutic resistance to c-Met/receptor tyrosine kinase (RTK) inhibitors in renal cancer remain unexplored. In renal cell carcinoma (RCC) cells, both AXL and c-Met are highly upregulated. Notably, we found that prolonged treatment with the c-Met/RTK inhibitor, cabozantinib (Cabo), a standard treatment for advanced-stage RCC, markedly increased total c-Met levels and promoted renal cancer cell proliferation.

Diabetic foot ulcers are severe diabetic complications, and promoting impaired angiogenesis is essential for wound healing. Pro-angiogenic galectin-3 is elevated in diabetic serum and promotes systemic insulin resistance that may impair wound healing. However, the exact role of galectin-3 in the regulation of diabetic wound healing remains unclear.

Atherosclerosis (AS) and cancer are major chronic diseases that pose considerable threats to human health. AS and cancer share common risk factors and pathogenic mechanisms, including oxidative stress, inflammation, aberrant apoptosis, uncontrolled proliferation, and angiogenesis (the formation of new blood vessels), with profound molecular interconnections. Galectin-3 (Gal-3), a multifunctional β-galactoside-binding protein, is involved in the regulation of various physiological functions such as the inflammatory microenvironment, cell proliferation, and macrophage polarization in both AS and cancer.

Purpose: Administration of the lymphocyte activation gene 3 (LAG-3) inhibitor relatlimab (RELA) and the PD-1 inhibitor nivolumab (NIVO) significantly prolonged progression-free survival (PFS) versus NIVO alone in patients with advanced melanoma treated in RELATIVITY-047. This report describes correlative analyses of biospecimens collected within that trial to better understand the mechanisms of action and identify patients who could benefit from treatment with NIVO + RELA.
Patients And Methods: Pre- and on-treatment peripheral blood samples from 563 patients were analyzed using flow cytometry for changes in 77 prespecified immune cell populations and using immunoassay for peripheral IFNγ.
