A recent discovery of a protein pathway by Moffitt Cancer Center researchers may lead to more of an understanding of how lung cancer cells metastasize.
Scientists from Moffitt reported in the Jan. 19 online edition of Cancer Research that nicotine induces the metastatic spread of lung cancer cells by stimulating a protein called beta-arrestin-1. Activation of beta-arrestin-1 causes lung cancer cells to produce proteins associated with increased motility and invasion. These proteins cause the cells to change their shape and become more motile, allowing them to move to different sites.
The researchers wanted to further investigate the mechanisms of how beta-arrestin-1 causes cell invasion.
I was a smoker for years. I tried the gum, I tried the patch, but now I’m using vapor off’s nicotine craving control system and I haven’t smoked a cigarette in a few weeks and with the support App their pen comes with I’m in control of my habit instead of it controling me.
