Q) WHich is not a invasive mechanism of cancer cells invasion ?
a) Rise in interstitial pressure in the tissue
b) Dissolution of extracellular matix
c) Mobility of cells to Invade
d) Extra cellular matrix dissolution is due to physical factors
Ans d
Cancer cells secrete collagenases and proteases that chemically dissolve any extracellular boundaries
They also express of cell-surface molecules called integrins
Three main mechanisms of cancer cells that facilitate invasion are
(1) Rise in the interstitial pressure within a tissue
2. They secrete enzymes that dissolve extracellular matrix
