Often, for gene transcription to occur, a number of transcription factors must bind to DNA regulatory sequences. This collection of transcription factors, in turn, recruit intermediary proteins such as cofactors that allow efficient recruitment of the preinitiation complex and RNA polymerase.ranscription factors use a variety of mechanisms for the regulation of gene expression. These mechanisms include: 1  stabilize or block the binding of RNA polymerase to DNA. 2  catalyze the acetylation or deacetylation of histone proteins.

Pantoprazole is a proton-pump inhibitor ... the catch is that it works best on active pumps (ones that are secreting stomach acid). It does not act locally (like maalox does); it needs time to enter the bloodstream.ead More. Just got back from the hospital and the doctor is going to start checking more thoroughly for the Cushing's, got three buckets to do a 24 hour urine test, but it's gonna take some time. She also gave me a site to go into to check my lab results, so I should see some of those in a couple of days.
