Plasma Ca2+ and PGE-2 levels correlated significantly (Pearson r = 0.6062 with p < 0.0001) as seen in Figure 2F. Tumour PTHrP levels were significantly lower in TB animals that had received diets enriched with fish oil and leucine compared to TB animals without supplementation as seen in Figure 2C. Tumour PTHrP levels did not correlate with plasma Ca2+ levels. Here, PTHLH is linked to neoplasm.
