Counting Receptors

Site specific administration of an injectable preparation of stanozolol has full body effects due to AAS induced androgenic and anabolic activity but only significant "localized" MGF, PGF-2, IGF-1 and IGF-2. MGF increases IGF-1 receptor sensitivity, PGF-2 increases androgen receptor count and sensitivity, and the localized IGF-1 production acts synergistically with the AAS. Oh, did I mention that the IGF-2 initiates an increase in vascular tissue growth for better nutrient supply ... 

Why do we have to increase dosages used if androgen receptor count is increased due to training Obviously AS receptor do not up-regulate to a noticeable degree then Is this the reason for the required higher doses each subsequent cycle for growth ... 

Finally, since the probabilities Pij t) converge to the steady-state values given by (6.18H6.21) as f 00, the average receptor counts in every state reach the following stationary values as time tends to infinity ... 

Thrombopoietic factors (no recombinant TPO product in clinical use at this time IL-11 [recombinant product oprelvekin] has marketing approval) stimulate the production of megakaryocyte precursors, megakaryocytes, and platelets [8]. Interleukin-11 has many effects on multiple tissues, and can interact with IL-3, TPO, and SCF. AMG 531, a recombinant peptibody in that binds to the thrombopoetin receptor Mpl and stimulates the production of platelets, is in phase 1 and 2 studies and has been shown to safely increase platelet counts in patients with immune thrombocytopenic purpura [9]. 

Chromatin remodeling, transcription factor modification by various enzyme activities, and the communication between the nuclear receptors and the basal transcription apparatus are accomplished by protein-protein interactions with one or more of a class of coregulator molecules. The number of these coregulator molecules now exceeds 100, not counting species variations and splice variants. The first of these to be described was the CREB-binding protein, CBP. CBP, through an amino terminal domain, binds to phosphorylated serine 137 of CREB and mediates transactivation in response to cAMP. It thus is described as a coactivator. CBP and...

Classification methods for leukemia have evolved from simple schemes that were largely phenotypic and considered only age, gender, WBC count, and blast morphology to now-complex methods that include biologic features such as cell-surface receptor features and cytogenetics. 

One test that was carried out when trying to compare levamisole receptor properties in SENS and LEVR isolates was to count the numbers of patches of recorded membranes that contained active channels. Figure 21.7 shows the proportion of patches from SENS and LEVR isolates that contained active patches at different concentrations of levamisole. It was... 

Among the most sensitive endpoints (on a body burden basis) are endometriosis, developmental neurobehavioural (cognitive) effects, hearing loss, developmental reproductive effects (sperm counts, female urinogenital malformations) and immuno-toxic effects, both adult and developmental. The most sensitive biochemical effects are CYP1A1/2 induction, hepatic retionid depletion, EGF-receptor down-regulation and oxidative stress. 

For the last forty years, many reports have emerged on the hormone-like effects of chemical compounds such as pesticides and industrial chemicals upon wildlife and humans. The effects of these materials are believed to be either direct or indirect. Direct effects involve positive or negative interactions with the hormone receptors. Indirect effects may result when the synthesis of hormones or their receptors is altered, or the transport, metabolism, or elimination of hormones is modified in some way. The discovery of hormone-like properties of some compounds was made long after their release into the environment. It was shown soon after their introduction that aviation crop dusters handling DDT had low sperm counts and workers at a plant producing the insecticide kepone were reported to have low libido, sperm counts and to be impotent. Subsequently, experiments conducted in laboratory animals demonstrated unambiguously the oestrogenic activity of these pesticides. 9 refs.
