1 C-KIT and GIST

Reactions: 


Interestingly, tumors with mutations in exon 11 of c-Kit's juxtamembrane region are particularly sensitive to imatinib, whereas those with exon 9 mutations (extracellular domain) respond better to sunitinib than imatinib. In the future, primary therapy for GIST may be determined by the specific molecular defect in c-Kit.

a. reservoir function of pulmonary veins

0 ALT and AST

Reactions: 



ALT is found predominately in the liver, with lesser quantities found in the kidneys, heart, and skeletal muscle.

As a result, the ALT is a more specific indicator of liver inflammation than the AST, as the AST may also be elevated in diseases affecting other organs, such as the heart or muscles. The AST is also elevated after a myocardial infarction, and during acute pancreatitis, acute hemolytic anemia, severe burns, acute renal disease, musculoskeletal diseases, and trauma.
