Investigating the effect of positional variation on mid-lactation mammary gland transcriptomics in mice fed either a low-fat or high-fat diet.

ABSTRACT: Little attention has been given to the effect of positional variation of gene expression in the mammary gland. However, more research is shedding light regarding the physiological differences that mammary gland location can have on the murine mammary gland. Here we examined the differentially expressed genes between mammary gland positions under either a low-fat diet (LFD) or a high-fat diet (HFD) in the mid-lactation mammary gland (lactation day 11; L11). Three-week old WT C57BL/6 mice were randomly assigned to either a low-fat diet (LFD) or high fat diet (HFD) (n = 3/group) and either the right thoracic mammary gland (TMG) or inguinal mammary gland (IMG) was collected from each dam for a total of 12 unique glands. Within each diet, differentially expressed genes (DEGs) were first filtere
