A1, an innovative fluorinated CXCR4 inhibitor, redefines the therapeutic landscape in colorectal cancer.

Background: Colorectal cancer (CRC) is a globally prevalent malignancy, primarily affecting the colon and rectum, characterized by uncontrolled cellular changes in the intestinal wall lining. Recent evidence underlines the significant role of the CXCL12/CXCR4 axis in the development of CRC, suggesting that inhibiting this pathway could be a promising therapeutic approach. This study focuses on investigating the potential of N, N''-thiocarbonylbis (N'-(3,4-dimethyl phenyl)-2,2,2-trifluoroacetimidamide) (A1), a novel fluorinated CXCR4 inhibitor, through a comprehensive analysis encompassing in silico, in vitro, and in vivo studies.

Chemokine CCL2 and its receptor CCR2 in different age groups of patients with COVID-19.

Background: Despite the development of various antiviral drugs, most of them are not effective in the treatment of coronavirus disease 2019 (COVID-19) as a hyperinflammatory disorder. Chemokine (C-C motif) ligand 2 (CCL2) is one of the critical CC chemokines involved in the pathogenesis and severity of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. This study aimed to investigate the expression of CCL2 and CC chemokine receptor 2 (CCR2) in COVID-19 patients.

Reciprocal Interactions Between Apelin and Noncoding RNAs in Cancer Progression.

Apelin, a bioactive peptide that serves as an endogenous ligand for the apelin receptor (APJ), is overexpressed in various types of cancers and contributes to cancer cell proliferation, viability, migration, angiogenesis, and metastasis, as well as immune deviation. Noncoding RNAs (ncRNAs) regulate gene expression, and there is growing evidence suggesting a bidirectional crosstalk between ncRNAs (including long noncoding RNAs [lncRNAs], circular RNAs [circRNAs], and microRNAs [miRNAs]) and apelin in cancers. Certain miRNAs can directly target the apelin and inhibit its expression, thereby suppressing tumor growth.

Unraveling the immunometabolism puzzle: Deciphering systemic sclerosis pathogenesis.

The article delves into the pathogenesis of systemic sclerosis (SSc) with an emphasis on immunometabolism dysfunctions. SSc is a complex autoimmune connective tissue disorder with skin and organ fibrosis manifestation, vasculopathy, and immune dysregulation. A growing amount of research indicates that immunometabolism plays a significant role in the pathogenesis of autoimmune diseases, including SSc.
