Cancer Med 2024; 13:e6800. [PMID: 38349028 PMCID: PMC10832341 DOI: 10.1002/cam4.6800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 11/06/2023] [Accepted: 11/27/2023] [Indexed: 02/15/2024] Open
Abstract
RGD peptide can be found in cell adhesion and signaling proteins, such as fibronectin, vitronectin, and fibrinogen. RGD peptides' principal function is to facilitate cell adhesion by interacting with integrin receptors on the cell surface. They have been intensively researched for use in biotechnology and medicine, including incorporation into biomaterials, conjugation to medicinal molecules or nanoparticles, and labeling with imaging agents. RGD peptides can be utilized to specifically target cancer cells and the tumor vasculature by engaging with these integrins, improving drug delivery efficiency and minimizing adverse effects on healthy tissues. RGD-functionalized drug carriers are a viable option for cancer therapy as this focused approach has demonstrated promise in the future. Writing a review on the RGD peptide can significantly influence how drugs are developed in the future by improving our understanding of the peptide, finding knowledge gaps, fostering innovation, and making drug design easier.

The pleiotropic effects of antithrombotic drugs in the metabolic-cardiovascular-neurodegenerative disease continuum: impact beyond reduced clotting. Clin Sci (Lond) 2021; 135:1015-1051. [PMID: 33881143 DOI: 10.1042/cs20201445] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 04/07/2021] [Accepted: 04/13/2021] [Indexed: 12/25/2022]
Abstract
Antithrombotic drugs are widely used for primary and secondary prevention, as well as treatment of many cardiovascular disorders. Over the past few decades, major advances in the pharmacology of these agents have been made with the introduction of new drug classes as novel therapeutic options. Accumulating evidence indicates that the beneficial outcomes of some of these antithrombotic agents are not solely related to their ability to reduce thrombosis. Here, we review the evidence supporting established and potential pleiotropic effects of four novel classes of antithrombotic drugs, adenosine diphosphate (ADP) P2Y12-receptor antagonists, Glycoprotein IIb/IIIa receptor Inhibitors, and Direct Oral Anticoagulants (DOACs), which include Direct Factor Xa (FXa) and Direct Thrombin Inhibitors. Specifically, we discuss the molecular evidence supporting such pleiotropic effects in the context of cardiovascular disease (CVD) including endothelial dysfunction (ED), atherosclerosis, cardiac injury, stroke, and arrhythmia. Importantly, we highlight the role of DOACs in mitigating metabolic dysfunction-associated cardiovascular derangements. We also postulate that DOACs modulate perivascular adipose tissue inflammation and thus, may reverse cardiovascular dysfunction early in the course of the metabolic syndrome. In this regard, we argue that some antithrombotic agents can reverse the neurovascular damage in Alzheimer's and Parkinson's brain and following traumatic brain injury (TBI). Overall, we attempt to provide an up-to-date comprehensive review of the less-recognized, beneficial molecular aspects of antithrombotic therapy beyond reduced thrombus formation. We also make a solid argument for the need of further mechanistic analysis of the pleiotropic effects of antithrombotic drugs in the future.

An anti-αVβ3 antibody inhibits coronary artery atherosclerosis in diabetic pigs. Atherosclerosis 2017; 258:40-50.

Abstract
BACKGROUND AND AIMS Diabetes is a major risk factor for the development of atherosclerosis. Hyperglycemia stimulates vascular smooth muscle cells (VSMC) to secrete ligands that bind to the αVβ3 integrin, a receptor that regulates VSMC proliferation and migration. This study determined whether an antibody that had previously been shown to block αVβ3 activation and to inhibit VSMC proliferation and migration in vitro, inhibited the development of atherosclerosis in diabetic pigs. METHODS Twenty diabetic pigs were maintained on a high fat diet for 22 weeks. Ten received injections of anti-β3 F(ab)2 and ten received control F(ab)2 for 18 weeks. RESULTS The active antibody group showed reduction of atherosclerosis of 91 ± 9% in the left main, 71 ± 11%, in left anterior descending, 80 ± 10.2% in circumflex, and 76 ± 25% in right coronary artery, (p < 0.01 compared to lesions areas from corresponding control treated arteries). There were significant reductions in both cell number and extracellular matrix. Histologic analysis showed neointimal hyperplasia with macrophage infiltration, calcifications and cholesterol clefts. Antibody treatment significantly reduced number of macrophages contained within lesions, suggesting that this change contributed to the decrease in lesion cellularity. Analysis of the biochemical changes within the femoral arteries that received the active antibody showed a 46 ± 12% (p < 0.05) reduction in the tyrosine phosphorylation of the β3 subunit of αVβ3 and a 40 ± 14% (p < 0.05) reduction in MAP kinase activation. CONCLUSIONS Blocking ligand binding to the αVβ3 integrin inhibits its activation and attenuates increased VSMC proliferation that is induced by chronic hyperglycemia. These changes result in significant decreases in atherosclerotic lesion size in the coronary arteries. The results suggest that this approach may have efficacy in treating the proliferative phase of atherosclerosis in patients with diabetes.

Abstract
Individuals with Type 2 diabetes mellitus (T2DM) are at increased risk of saphenous vein (SV) graft stenosis following coronary artery bypass. Graft stenosis is caused by intimal hyperplasia, a pathology characterized by smooth muscle cell (SMC) proliferation and migration. We hypothesized that SV-SMC from T2DM patients were intrinsically more proliferative and migratory than those from nondiabetic individuals. SV-SMC were cultured from nondiabetic and T2DM patients. Cell morphology (light microscopy, immunocytochemistry), S100A4 expression (real-time RT-PCR, immunoblotting), proliferation (cell counting), migration (Boyden chamber assay), and cell signaling (immunoblotting with phosphorylation state-specific antibodies) were studied. SV-SMC from T2DM patients were morphologically distinct from nondiabetic patients and exhibited a predominantly rhomboid phenotype, accompanied by disrupted F-actin cytoskeleton, disorganized alpha-smooth muscle actin network, and increased focal adhesion formation. However, no differences were observed in expression of the calcium-binding protein S100A4, a marker of rhomboid SMC phenotype, between the two cell populations. T2DM cells were less proliferative in response to fetal calf serum than nondiabetic cells, but both populations had similar proliferative responses to insulin plus PDGF. Under high glucose concentration conditions in the presence of insulin, migration of diabetic SV-SMC was greater than nondiabetic cells. Glucose concentration did not affect SV-SMC proliferation. No differences in insulin or PDGF-induced phosphorylation of ERK-1/2 or components of the Akt pathway (Akt-Ser473, Akt-Thr308, and GSK-3beta) were apparent between the two populations. In conclusion, SV-SMC from T2DM patients differ from nondiabetic SV-SMC in that they exhibit a rhomboid phenotype and are more migratory, but less proliferative, in response to serum.

Abstract
It is well accepted that complex biological processes such as angiogenesis are not controlled by a single family of molecules or individually isolated signaling pathways. In this regard, new insight into the interconnected mechanisms that regulate angiogenesis might be gained by examining this process from a more global network perspective. The coordination of signaling cues from both outside and inside many different cell types is required for the successful completion of angiogenesis. Evidence is accumulating that the multifunctional integrin family of cell adhesion receptors represent an important group of molecules that play active roles in sensing, integrating, and distributing a diverse set of signals that regulate many cellular events required for angiogenesis. Given the ability of integrins to bind numerous extracellular ligands and transmit signals in a bi-directional fashion, we will discuss the multiple ways by which integrins may serve as a functional hub during pathological angiogenesis. In addition, we will highlight potential imaging and therapeutic strategies based on the expanding new insight into integrin function.
