Man and mouse share genome structures

...o Bernstein is the unusual density of histone tags spread over the regions of genome containing the HOX genes, which are key regulators of development. "In most of the genome, we see short stretches associated with activated histones," Bernstein said. "However, in the HOX regions, we see huge stretches of ...

Topical treatment shown to inhibit HIV and herpes simplex virus infection

...nd genital herpes plays a major role in the sexual spread of HIV. The researchers conducted a prospective, randomized, double blind, placebo-controlled study among 20 HIV-infected women to assess the antiviral activity of PRO 2000 in cervicovaginal lavage (CVL) fluid collected before and one hour after adm...

Male circumcision reduces risk of HIV transmission from women to men
