Overexpression and chemotherapy-induced modulation of LDH-A and GLUT-1 correlated with poor MM prognosis. Combined inhibition of these two metabolic determinants impeded MM cell migration, stimulated ROS production and apoptosis, and affected spheroids' growth, offering promise for new treatment development.

Young patients with DPM have strong personal and family histories of cancer, and heterogeneous somatic and germline alterations, indicating divergent underlying biology. With the increasing prevalence of young adults with cancers, mesotheliomas, although uncommon, should be on the differential for patients even without asbestos exposure history in this age group.
In this large PM cohort,CDKN2A, NF2, and TP53 alterations were associated with worse OS, while BAP1 alterations were associated with better prognosis, independent of clinical variables and histology. Modeling suggests that genomic alterations provide additional prognostic information beyond anatomic TNM and clinicopathologic features.

Data obtained clearly highlighted how TGF-β inhibition, through the silencing or treatment of MPM cells with antibody anti-TGF-β (Fresolimumab), significantly reduces cell proliferation (MTT, PCNA) and prevents metastasis, reducing EMT and decreasing the invasiveness and migration of MPM cells...Taken as a whole, targeting TGF-β will represent a starting point for future improvements in MPM management. This is particularly important as we foresee a growing increase in MPM in the coming years.
Our drug screening assay showed that the fatty acid synthase (FASN) inhibitor cerulenin demonstrates strong and selective antiproliferative properties against NF2/CDKN2A(p16)-deficient PM cells, surpassing the effects of C75, cisplatin or pemetrexed. These findings suggest that FASN might play a role in the tumorigenesis of PM cells through the regulation of mitochondrial dynamics. This research offers a novel perspective on the potential development of precision medicine for PM.
