KISS1 belongs to the family of metastasis suppressor genes. However, its role is not limited to blocking cancer metastasis. KISS1 and its by-product kisspeptins (KP) are important players in regulating the reproductive axis in different species and have new roles in controlling physiological balance and social behaviors. These diverse functions point to KISS1 as a potential therapeutic molecule. Here we describe a methodology to detect KISS1 and KP from cell lysate and conditioned media in cell lines. This will serve as a critical tool to study KISS1 processing in KP.

Novel Dehydroabietylamine C-Ring Schiff Base Derivatives: Synthesis, Antiproliferative activity, DNA binding and Molecular docking.
Chem Asian J
January 2025
Nanjing Forestry University, College of Science, CHINA.
A series of Dehydroabietylamine (DHAA) C-ring Schiff derivatives, L3-L20, were synthesized and their in vitro cytotoxic activity against the human tumor cell lines cervix HeLa, breast MCF-7, lung A549, liver HepG2, and the nonmalignant cell line umbilical vein HUVEC was investigated. Most of the compounds showed varying degrees of anticancer activity against HeLa cell lines while demonstrating lower toxicity to normal HUVEC cells compared to DHAA and doxorubicin (DOX), especially compound L19, which not only enhanced the anticancer activity of DHAA, but also significantly reduced the toxicity to normal cells, achieving a selectivity index (SI) 118 times higher than that of DHAA and 245 times higher than that of DOX. In addition, compound L19 induced apoptosis in HeLa cells in a dose-dependent manner and arrested the cell cycle in S phase.

Background: Several approaches are being explored for engineering off-the-shelf chimeric antigen receptor (CAR) T cells. In this study, we engineered chimeric Fcγ receptor (FcγR) T cells and tested their potential as a versatile platform for universal T cell therapy.
Methods: Chimeric FcγR (CFR) constructs were generated using three distinct forms of FcγR, namely CD16A, CD32A, and CD64.
Targeting of the G9a, DNMT1 and UHRF1 epigenetic complex as an effective strategy against pancreatic ductal adenocarcinoma.
J Exp Clin Cancer Res

Hepatology Laboratory, Solid Tumors Program, CIMA, CCUN, University of Navarra, Pamplona, Spain.
Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer with limited treatment options and a poor prognosis. The critical role of epigenetic alterations such as changes in DNA methylation, histones modifications, and chromatin remodeling, in pancreatic tumors progression is becoming increasingly recognized. Moreover, in PDAC these aberrant epigenetic mechanisms can also limit therapy efficacy.

Background: The advancement of nanotechnology underscores the imperative need for establishing in silico predictive models to assess safety, particularly in the context of chronic respiratory afflictions such as lung fibrosis, a pathogenic transformation that is irreversible. While the compilation of predictive descriptors is pivotal for in silico model development, key features specifically tailored for predicting lung fibrosis remain elusive. This study aimed to uncover the essential predictive descriptors governing nanoparticle-induced pulmonary fibrosis.

Department of Pharmacology, SUNY Upstate Medical University, Syracuse, NY, 13210, USA.
Background: Bok is a poorly characterized Bcl-2 protein family member with roles yet to be clearly defined. It is clear, however, that Bok binds strongly to inositol 1,4,5-trisphosphate (IP) receptors (IPRs), which govern the mobilization of Ca from the endoplasmic reticulum, a signaling pathway required for many cellular processes. Also known is that Bok has a highly conserved phosphorylation site for cAMP-dependent protein kinase at serine-8 (Ser-8).
