| abstract |
Methods and compositions for improving the delivery and/or efficacy of a therapy (e.g., an anti-cancer, anti-fibrotic or anti-inflammatory therapy) are disclosed. The invention is based, at least in part, on the discovery that metformin, a widely prescribed anti-diabetic drug, can affect the tumor microenvironment (e.g., directly, i.e., independent of its effects on cancer cells themselves or tumor metabolism). In embodiments described herein, metformin has been shown to reduce the amount of extracellular matrix, including collagen 1 and hyaluronan, in the fibro-inflammatory tumor microenvironment in a subject (e.g., a subject with a desmoplastic tumor). |
