AI Article Synopsis
- NME1 is a metastasis-suppressor gene that inhibits metastatic activity in various cancers without altering their growth.
- Research involved removing Nme1 and Nme2 genes in a mouse model of UVR-induced melanoma to evaluate their roles.
- The results showed increased metastatic activity in both male and female mice lacking these genes, with a notable increase in females, highlighting Nme2's role as a metastasis-suppressor for the first time in this context.
Article Abstract
NME1 is a metastasis-suppressor gene (MSG), capable of suppressing metastatic activity in cell lines of melanoma, breast carcinoma and other cancer origins without affecting their growth in culture or as primary tumours. Herein, we selectively ablated the tandemly arranged Nme1 and Nme2 genes to assess their individual impacts on metastatic activity in a mouse model (HGF:p16) of ultraviolet radiation (UVR)-induced melanoma. Metastatic activity was strongly enhanced in both genders of Nme1- and Nme2-null mice, with stronger activity in females across all genotypes. The study ascribes MSG activity to Nme2 for the first time in an in vivo model of spontaneous cancer, as well as a novel metastasis-suppressor function to Nme1 in the specific context of UVR-induced melanoma.

Exploring the druggability of the UEV domain of human TSG101 in search for broad-spectrum antivirals.

Department of Physical Chemistry, Institute of Biotechnology, and Unit of Excellence in Chemistry Applied to Biomedicine and Environment, School of Sciences, University of Granada, Granada, Spain.
The ubiquitin E2 variant domain of TSG101 (TSG101-UEV) plays a pivotal role in protein sorting and virus budding by recognizing PTAP motifs within ubiquitinated proteins. Disruption of TSG101-UEV/PTAP interactions has emerged as a promising strategy for the development of host-oriented broad-spectrum antivirals with low susceptibility to resistance. TSG101 is a challenging target characterized by an extended and flat binding interface, low affinity for PTAP ligands, and complex binding energetics.

Background: FOXF2 was reported to involve in a variety of biological behaviors that include the development of the central nervous system, tissue homeostasis, epithelia-mesenchymal interactions, regulation of embryonic development, and organogenesis.
Purpose: Understanding how FOXF2 influences the growth and development of cancer could provide valuable insights for researchers to develop novel therapeutic strategies.
Results: In this review, we investigate the underlying impact of FOXF2 on tumor cells, including the transformation of cellular phenotype, capacity for migration, invasion, and proliferation, colonization of circulating cells, and formation of metastatic nodules.
