Because non-genomic pathways include any mechanism that is not a genomic effect, there are various non-genomic pathways. However, all of these pathways are mediated by some type of steroid hormone receptor found at the plasma membrane. [13] Ion channels, transporters, G-protein coupled receptors (GPCR), and membrane fluidity have all been shown to be affected by steroid hormones. [9] Of these, GPCR linked proteins are the most more information on these proteins and pathways, visit the steroid hormone receptor page.

Anabolic steroid hormones are synthetic substances that are related to the male sex hormones. They have the same mechanism of action within the body. Anabolic steroid hormones stimulate the production of protein, which is used to build muscle . They also lead to an increase in the production of testosterone. Testosterone is the hormone responsible for the development of male reproductive organs and male secondary sex characteristics. Testosterone is also critical in the development of lean muscle mass. Anabolic steroid hormones also promote the release of the growth hormone which stimulates growth, especially skeletal growth.

Sex hormone-binding globulin (SHBG) is thought to mainly function as a transporter and reservoir for the estradiol and testosterone sex hormones. However it has also been demonstrated that SHBG can bind to a cell surface receptor (SHBG-R). The SHBG-R has not been completely characterized. A subset of steroids are able to bind to the SHBG/SHBG-R complex resulting in an activation of adenylyl cyclase and synthesis of the cAMP second messenger. [19] Hence the SHBG/SHBG-R complex appears to act as a transmembrane steroid receptor that is capable of transmitting signals to the interior of cells.

Our new Rxi ® -1ms column, designed for GC-MS applications, provides the ultra-low bleed and exceptional inertness needed for analyzing urinary steroid hormones. For this application we derivatized six sex hormones, using methoxylamine HCl and trimethylsilyl imidazole to improve chromatography. Figure 1 shows this variety of derivatized steroid sex hormones, analyzed in less than 25 minutes by using an Rxi ® -1ms column. Note that these compounds elute at temperatures near or above 300°C and that bleed from the Rxi ® -1ms column is negligible at these temperatures. The Rxi ® -1ms column exhibits the inertness needed to produce Gaussian peaks and excellent resolution.
