Dasatinib is an orally active nonselective tyrosine kinase inhibitor used to treat certain types of adult leukemia. By inhibiting PDGFR-β and SFKs in both tumor cells and tumor-associated endothelial cells, dasatinib inhibits tumor growth and angiogenesis. Herein, dasatinib derivatives modified with hydrophobic chains were prepared and evaluated for their in vitro antiproliferative selectivity and their in vivo antiangiogenic activity. For one of the derivatives, modified with a long perfluorinated chain, a significant enhancement in antiangiogenic activity was observed. Combined, these results suggest a possible generic route to modulate the angiostatic activity of drugs.

Type 3 macular neovascularization (MNV) is a unique form of neovascular age-related macular degeneration (AMD) that presents distinct pathogenetic features, clinical manifestations, and prognostic considerations when compared to types 1 and 2 MNV. Insights gained from clinicopathological correlations, bridging in vivo examination techniques with ex vivo histological analysis, have significantly enhanced our comprehension of this MNV phenotype, shaped current management strategies and influenced future directions for therapeutics. The particularities of type 3 MNV, which may largely stem from its origin from the retinal vasculature, are critically important for predicting the disease course.

Article Synopsis
  • Mesenchymal stem/stromal cells (MSCs) play a crucial role in tissue maintenance and respond to microenvironment changes caused by injury, with Toll-like receptors (TLRs) acting as important sensors for these changes.
  • Research focused on the expression and role of TLR2 in MSCs, showing that its activation enhances MSC immunoregulatory and angiostatic functions in relation to monocytes/macrophages and in a mouse model of corneal inflammation.
  • The study identified aldo-keto reductase family 1 member C1 (AKR1C1) as a key gene induced by TLR2 activation, which protects MSCs from cell death, boosts the secretion of anti-inflammatory signals, and ultimately helps reduce inflammation

Anti-angiogenic therapy is an established method for the treatment of several cancers and vascular-related diseases. Most of the agents employed target the vascular endothelial growth factor A, the major cytokine stimulating angiogenesis. However, the efficacy of these treatments is limited by the onset of drug resistance.

Dermaseptin B2 (DrsB2) is an antimicrobial peptide with anticancer and angiostatic properties. We aimed to assess the in vitro inhibitory effect of pDNA/DrsB2 on the growth of breast cancer cells and its impact on the expression of genes involved in the BAX/BBC3/AKT pathway. The nucleic acid sequence of DrsB2 was artificially synthesized and inserted into the pcDNA3.

Background/aims: Endothelial cells (ECs) play a crucial role in various physiological processes, particularly those related to the cardiovascular system, but also those affecting the entire organism. The biology of ECs is regulated by multiple biochemical stimuli and epigenetic drivers that govern gene expression. We investigated the angiogenic potential of ECs from a protein citrullination perspective, regulated by peptidyl-arginine deiminases (PADs) that modify histone and non-histone proteins.
