Genes changes

Sickle cell disease again provides an excellent example of how recombinant DNA technology can be applied to the smdy of human disease. The substitution of T for A in the template strand of DNA in the P-globin gene changes the sequence in the region that corresponds to the sixth codon from... 

In a separate study on the effects of captopril on rats after myocardial infarction, Davis et al. [169] identified 37 genes that were seen to change between myocardial infarct and sham operated rats. 10 of these gene changes were inhibited by captopril treatment. The 37 genes clustered into 11 functional groups, of which 6 included at least one of the 10 genes inhibited by captopril. 

Germline mutation A gene change in the body s reproductive cells (egg or sperm) that becomes incorporated into the DNA of every cell in the body of offspring germline mutations are passed on from parents to offspring. Also called hereditary mutation. [NIH]...

Synergy with catecholamines. The lipid soluble steroid molecules enter cells and bind the intracellular receptors. This results in up-regulation of specific genes, changes in RNA production, and protein synthesis. 

GAPDH is inhibited to more than 80 % by a toxic dose of paracetamol. It seems likely that the initiating events are chemical interactions and protein damage and that gene changes may arise later, as a response and as part of the repair processes. 

Water-insoluble hormones (steroid, retinoid, and thyroid hormones) readily pass through the plasma membrane of their target cells to reach their receptor proteins in the nucleus (Fig. 23-4). With this class of hormones, the hormone-receptor complex itself carries the message it interacts with DNA to alter the expression of specific genes, changing the enzyme complement of the cell and thereby changing cellular metabolism (see Fig. 12 10). 

Single gene changes may not be enough for coordinated pathway engineering.
