Additionally, a positive correlation was detected between increased GRP75 levels in the serum and progressive WAT atrophy in LLC tumour-bearing models (Supplementary Fig. 4h, R2 = 0.5234, P < 0.0001), suggesting the potential utility of GRP75 as a biomarker of WAT atrophy for monitoring cachexia progression. The gene discussed is HSPA9; the disease is Cachexia.
