An important find from the detection of leptin, adiponectin, AdipoR1, and AdipoR2 mRNA in breast cancer cells through endpoint PCR was that in HCC1937, a triple-negative cell line with a mutation in BRCA1 [44], these proteins and receptors are also found to be expressed, information that had not been reported in the literature. Here, ADIPOR1 is linked to breast carcinoma.
