7 Mechanisms of Cancer Resistance |
|
Definition
1.) decreased uptake by drug transporter 2.) Pgp efflux pump overexpression (multidrug) 3.) increased/mutated drug target 4.) repaire of dna damage 5.) drug metabolism 6.) change in membrane lipids 7.) compartmentalization (drug cannot reach hypoxic core) |

Mechanisms of DNA Repair (3) |
|
Definition
1.) Base Excision Repair: remove mismatched base (glycosylase); replace with new (dnapol); religate. Cell cycle arrest will occur if mech is overwhelmed 2.) Mismatch Repair: proteins identify mismatch & replace large sections. If damage is too great it will trigger apoptosis 3.) Nonhomo Endjoining Repair: reseals ds break |
