This method allows one to control gene activity in space and time in almost any tissue of the mouse, thus opening new avenues for studying gene function and for establishing sophisticated animal models of human diseases. A major technical advance in terms of in vivo inducibility was the development of ligand-dependent Cre recombinases that can be activated by administration of tamoxifen to the animal. Here we describe how tamoxifen-dependent Cre recombinases, so-called Cre ER recombinases, work and how they can be used to generate time- and tissue-specific mouse mutants. The focus will be on the Cre ER transgenic mouse lines and present protocols that detail the generation of experimental mice for inducible gene knockout studies, the induction of recombination by tamoxifen treatment, and the analysis of the quality and quantity of recombination by reporter gene and target gene studies. Most of the protocols can also be used as general guidelines for the generation and characterization of Cre/lox-mediated genome modifications in mice.

    To advance the study of gene function, scientists were in search of inducible promoters capable of controlling eukaryotic gene expression. Several endogenous promoters had been identified that responded to stimuli, such as hormones or metal ions; however, these systems were confounded by secondary effects. Scientists began to pursue a non-endogenous system for eukaryotes. coli presented the best candidates for inducible expression. Bacterial systems were tested for functionality in mammalian cells. The lac system with the inducer was tested first, and IPTG was found to be inefficient, resulting in low levels of induction. In 1992, Manfred Gossen and Hermann Bujard tested the tet system in a mammalian cell system (He La) and found that the tet system was functional, and had rapid induction with efficient tetracycline uptake. Please search our full site for all tetracycline plasmids. The Cre-lox system, derived from P1 bacteriophage, is a potent and specific system for controlling gene expression. The protein Cre recombinase recognizes 34 bp lox P sites, and the orientation and location of the lox P sites determines how the genetic material will be rearranged. The schematic below shows the three types of rearrangements: inversion, deletion and translocation. For a more thorough introduction, check out Addgene’s Cre-lox blog post. Based on these Cre-lox recombination principles, scientists have developed constructs to activate/inactivate genes when Cre is present. By expressing Cre at specific times or locations, you can precisely control expression of your gene of interest. Many Cre constructs also contain fluorescent labels that indicate if recombination has occurred, allowing for direct comparison of Cre and Cre- cells.

    South Asian Women's Leadership Forum (SAWLF) is the first not-for-profit organization dedicated to the advancement of South Asian women and girls (U. SAWLF participants are public and private sector professionals that number over 4,000 across the U. Through a combination of events, mentoring, and education, SAWLF serves as a platform for professional women to meet and assist one another with individual, professional and business objectives and, ultimately, leave a network and legacy for the women that follow us to utilize and build upon. The SAWLF mentoring initiative partners SAWLF members with school age girls from diverse communities within the City of New York. Through our bi-annual conference, Congress, SAWLF is committed to providing women professionals a forum in which to interact and learn from successful women leaders from around the world. The visibility of prominent individuals who are willing to share their personal experiences of challenge and achievement is critical to the success of this program. SAWLF Distinguished Speakers and Alumni Include: SAWLF's success can be contributed to its many volunteers and speakers. They devote their time, and, in the true spirit of our organization, share their network and resources in order to support our events and programs. Since its inception, SAWLF has hosted or collaborated in over 150 distinct programs.

    Most guys know that these meds don’t magically give them an erection. Still, 3 percent of study participants reported they weren’t getting enough sexual stimulation when trying them out. If you’re not aroused, you might as well have just popped a placebo. When you get sexually excited, your brain sends a signal via the nerves down to your penis. This releases a chemical into the muscle of the penis, which then sparks the production of another chemical—the one your ED meds work on to give you a boner. If you’re not aroused, that second chemical wouldn’t form in the first place. Related: The Scientific Reason You Wake Up With Morning Wood “We tell men not to take the drug and expect miracles happening without doing some work—foreplay, things like that,” says Dr. “It will not work unless you have some form of sexual stimulation, be it touch, taste, smell, whatever that is.” Unless you’ve reached the max dosage, don’t assume your meds aren’t going to work for you—an error shared by 31 percent of the study participants. It might be tempting to start at the lowest dose—who wants to take more medication than they need?
