Alpinetin has been shown to inhibit high-fat diet-induced lung cancer progression by suppressing cell proliferation and lipid accumulation in tumor cells, as well as restraining macrophage accumulation and chemokine secretion in tumor tissues.
Alpinetin (ALP) has been reported to act as an anticancer agent. This study was carried out to elucidate the effect of ALP on high-fat diet (HFD)-induced aggressive cancer progression. C57BL/6 mice were fed with a control diet (CD) or HFD and administered with ALP. Following 6 weeks of feeding, mice were inoculated subcutaneously with Lewis lung carcinoma cells (LLC) to develop transplanted lung tumour. ALP suppressed cell proliferation which drives HFD-induced lung cancer progression. ALP inhibited lipid accumulation in tumour and tumour cells cultured in vitro. qPCR and ELISA analysis of tumour tissues revealed ALP restrained macrophages accumulation, M2s polarization and chemokine secretion. Further, in macrophages cultured in tumour cells conditioned medium (CM), ALP was confirmed to decrease M2s markers expression and chemokine production under high fat. These results demonstrate that ALP suppresses HFD-promoted harmful changes in tumour microenvironments which are crucial in curbing pulmonary tumour aggravation.
