First of all, thermogenin is an uncoupling protein found in the mitochondria of brown adipose tissue.
carbohydrates already have enough energy for the survival by their oxidation through the respiration process.
Hence, the researchers would seek to induce thermogenin expression only in adipose tissue and not in tissues that rely primarily on carbohydrates for energy.
why would researchers seek to induce thermogenin expression only in adipose tissue and not in tissues...
Tissue-specific microarray analysis facilitates the comparison of gene expression in different tissues. In order to prepare a sample for microarray analysis, messenger RNA (mRNA) is extracted from a particular tissue, reverse transcribed to generate complementary DNA (cDNA), and labeled with a fluorescent probe. The microarray below shows comparison of gene expression in stomach and intestinal tissues. The cDNA from stomach tissue was labeled with red fluorescent probes, whereas the cDNA from the intestinal tissue was labeled with green fluorescent probes....
Why would an increase in brown adipose tissue be helpful in reducing a patient's body weight?
Why would increasing the amount of uncoupling proteins in adipose tissue constitute a reasonable approach to facilitate weight loss?
Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the liver and testes. For this to happen there must be direct communication between the extracellular matrix and the developing cells. Which kind of transmembrane protein would most likely be involved in this kind of induction?
In a recent study, the expression profiles for 6900 genes in normal and malignant breast tissues from rats were compared. RNA was extracted using the following tissues: a. breast tissue from virgin rats b. breast tissue from pregnant rats c. breast tissue from lactating rats d. breast carcinomas induced by the meat-derived carcinogen, PhIP e. breast carcinomas induced by the experimental carcinogen, DMBA Tissues a, b, c were grouped together as normal and tissues d, e were grouped as carcinoma...
The adipose tissue is an important regulator of energy metabolism. In obese patients with insulin resistance, fatty liver develops in only a subset of the population. What is the result of adiiponectin administration to mice while feeding alcohol in Figure 2? Figure 2 Effects of adiponectin on alcohol-induced steatosis and inflammation. Liver specimens were taken from mouse livers after 5 weeks of LC diet (a and d), LE diet (b and e), or LE + Ad diet (c and f)...
Why would it be advantageous to plants to be able to get acetyl-CoA from fatty acids? -Fatty acids are the macromolecule most easily taken up by the roots of the plant -Plants lack the ability to synthesize carbohydrates -Energy derived from photosynthesis primarily comes in the form of fatty acids -Seeds have a limited amount of space and fatty acids are the most energy dense macromolecule

Why would a bacteria cell benefit from expressing the lac operon only in the presence of lactose? 1. The cell benefits by limiting the energy spent on the expression of the lac operonA. 2. The cell needs the lac operon to be expressed in order to obtain energy from lactose. 3. The cell doesn’t benefit, it would be better if the lac operon were expressed all of the time. 4.The production of lac operon proteins requires energy, but their production...
