MYH14 and vitamin D deficiency: Using two differential analysis approaches to analyse the LC-MS/MS assay data we have identified differential expression of a range of proteins including peroxidredoxin (PRDX) 1, 5, and 6, which were decreased in P7 lungs of vitamin D deficient mice compared to vitamin D replete mice and myosin (MYH) 9, 11, and 14 were increased in P7 lungs with vitamin D deficiency.
