What the Research Shows Recent research on semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) has revealed concerning trends about body composition changes: A 2023 analysis of STEP trial data found that approximately 39% of weight lost on semaglutide was lean body mass 1 Research on tirzepatide showed similar patterns, with 30-40% of total weight loss coming from lean tissue 2 Comparative studies indicate GLP-1 users may lose more muscle than people losing weight through diet and exercise alone 3 For context: if you lose 50 pounds on a GLP-1 medication, 15-20 pounds might be muscle mass
M2-like tumour-associated macrophage-secreted IGF promotes thyroid cancer stemness and metastasis by activating the PI3K/AKT/mTOR pathway
Recent single-cell transcriptomic analyses in mice revealed at least five transcriptionally distinct Vmes subtypes, each expressing different combinations of ion channels, receptors, and mechanosensory proteins
These usually appear in the first few days as your body adjusts to slower digestion and appetite changes
The CheckMate 238 (NCT02388906) trial compared nivolumab with ipi10 and found that nivolumab produced superior RFS and had a more tolerable safety profile.[24] Pembrolizumab produced superior RFS compared with placebo, with data on OS still maturing in the MK-3475-054/KEYNOTE-054 trial (NCT02362594).[25] Dabrafenib plus trametinib produced superior RFS compared with placebo, with data on OS still maturing in the COMBI-AD trial (NCT01682083).[26] Single-agent BRAF-inhibitor therapy with vemurafenib did not show improved RFS compared with placebo in the BRIM8 trial (NCT01667419).[27] The benefit of immunotherapy with ipilimumab, nivolumab, and pembrolizumab has been seen regardless of programmed death-ligand 1 (PD-L1) expression or the presence of BRAF pathogenic variants
