Published: September 2013

Kisspeptins (KP), peptide products of the kisspeptin-1 (KISS1) gene are the endogenous ligands for a G protein-coupled receptor (GPCR) - KP receptor (KISS1R). KISS1R couples to the Gαq/11 signaling pathway. KISS1 is a metastasis suppressor gene and the KP/KISS1R signaling has anti-metastatic and tumor-suppressant effects in numerous human cancers. On the other hand, recent studies indicate that KP/KISS1R pathway plays detrimental roles in breast cancer. In this review, we summarize recent developments in the understanding of the mechanisms regulating KP/KISS1R signaling in breast cancer metastasis.

Nano 2 Micro Material Design Lab, Department of Chemical Engineering and Technology, IIT (BHU), Varanasi 221005, India.

Herein, fluorescent calcium carbonate nanoclusters encapsulated with methotrexate (Mtx) and surface functionalized with chitosan (25 nm) (@Calmat) have been developed for the imaging and treatment of triple-negative breast cancer (TNBC). These biocompatible, pH-sensitive nanoparticles demonstrate significant potential for targeted therapy and diagnostic applications. The efficacy of nanoparticles (NPs) was evaluated in MDA-MB-231 TNBC cell lines.

In this work, we evaluated the anticancer activity of compounds 1 (mononuclear) and 2 (dinuclear) copper(II) coordination compounds derived from the ligand 5-methylsalicylaldehyde 2-furoyl hydrazone (H2L) over MDA-MB-231 Triple-negative breast cancer (TNBC) cells, and compared their activities with that of a newly synthesized, protonated, dinuclear analogue of 2 (complex 3). Here, we report the synthesis of compound 3 and it has been characterized in the solid state (X-ray diffraction, FTIR) and in solution (EPR, UV-Vis, ESI) as well as its electrochemical profile. Complexes 1-3 impaired cell viability from 0.

Importance: Transportation insecurity and lack of social support are 2 understudied social determinants of health that contribute to excess morbidity, mortality, and acute health care utilization. However, whether and how these social determinants of health are associated with cancer screening has not been determined and has implications for preventive care.

Objective: To determine whether transportation insecurity or social support are associated with screening adherence for colorectal, breast, and cervical cancer.

Importance: Triple-negative breast cancer is an aggressive subtype with a high incidence in young patients, a high incidence in non-Hispanic Black women, and a high risk of progression to metastatic cancer, a devastating sequela with a 12- to 18-month life expectancy. Until recently, one strategy for treating early-stage triple-negative breast cancer was chemotherapy after surgery. However, it was not known whether the addition of immune therapy to postsurgery chemotherapy would be beneficial.
