Janus- faced molecules are also relevant to cancer studies; their presence often poses contradicting motives in research. Proteoglycans are one such class of molecules that display this duality, under certain chemical conditions these molecules can emerge as inhibitors or promoters. Recent studies have shown that proteoglycans can play an integral role in the metastasis of cancer. Another molecule that falls within this class of molecules is DKK1. This molecule's presence can trigger cancers to display both metastatic as well as anti-metastatic properties especially pertaining to breast cancers. It has been studied that DKK1 secretion can be associated with promoting breast cancer metastasis to the bone as well as the suppression of metastasis to the lungs. Botulinum neurotoxins also portray these dichotomous roles. This specific molecule is formed by Clostridium Botulinum, a spore forming bacteria. If this bacteria contaminates food, the results can be fatal and can lead to death. Yet, despite their toxicity which is lethal even in small doses, these molecules can be used in a wide array of pharmacological applications; one such application is the one utilized in cosmetology.
