What are the major endocrine glands? Which tissues also produce hormones? What hormone is secreted by extra-embryonic tissue to maintain pregnancy? Which hormone stimulates hemopoiesis (making blood cells)? What is the part of sperm containing centrioles?
Which enzyme(s) would you expect to find in a cell that synthesizes progesterone? A) P450 side chain cleavage. B) 3 beta-hydroxysteroid dehydrogenase. C) Aromatase. D) All of the above. E) Both A and B. Identify the following: A type of digestion that involves chemical reactions catalyz...
35 Such PRL-R are expressed by human epidermal keratinocytes in vitro36; in the dermal papilla, matrix, outer root sheath, lower regions of the inner root sheath, and connective tissue sheath in wool follicles of sheep37, 38; and in the outer root sheath of anagen HFs of mice.22, 23 ...
3). Using primers specific for hi-GIRK2, a unique PCR product of the expected size was observed to be most abundant in insulinoma and cerebellum RNA, while lower levels of expression were detected in all other tissues examined, including human islet and pancreatic exocrine tissue (Fig. 3)....
Not only is it a vital component of cell membranes without which the cell cannot function, but it is also the precursor to all steroid hormones, bile acids, and oxysterols, which by themselves are important regulatory molecules in many metabolic pathways. Cholesterol and fatty acids as building...
BROWN adipose tissueTHYROID hormone regulationTISSUE metabolismMETABOLIC regulationMETABOLIC disordersThyroid hormones (THs) are important modulators of many metabolic processes, being strictly associated with the control of energy balance, mainly through activities on the brain, white and brown adipose tissue...
Bisphenols such as bisphenol A (BPA), S (BPS), C (BPC), F (BPF), AF (BPAF), tetrabromobisphenol, nonylphenol, and octylphenol are plasticizers used worldwide to manufacture daily-use articles. Exposure to these compounds is related to many pathologies of public health importance, such as in...
by the enzymes a- amylase and B-amylase. It is straight chain polymer. Amylopectin is a branched chain polymer of several D-glucose molecules. 80% of amylopectin is present in starch. Plants are able to synthesize glucose, and the excess glucose is stored as starch in different plant parts...
fungi for example, the Gal 4 promoter, the ADC (alcohol dehydrogenase) promoter, PGK (phosphoglycerol kinase) promoter, alkaline phosphatase promoter; and the animal transcriptional control regions, which exhibit tissue specificity and have been utilized in transgenic animals: elastase I gene control ...
In one sense, translation is a typical metabolic process which must be regulated to balance the available energy resources, the growth requirements of the cell, and the signals being received by the cell from its environment, such as those communicated by hormones. Unlike other cellular processes,...
