Fibroblasts were isolated from cyclin A1-/-A2f/f embryos cultured and transduced with Cre-expressing viruses thereby ablating all cyclin A expression (Figures 1D and S1A). (immune-source.com)
Activation of PKCd with a phorbol ester leads to elevated cyclin D1 expression and an hyperphosphorylated Rb state. (conicet.gov.ar)

2003 Cyclin A2f/f mice were viable and phenotypically normal (data not shown) consistent with our expectation that this "floxed" cyclin A2 allele is usually functionally wild-type. (immune-source.com)
Hence deletion of the "floxed" cyclin A2 sequences converts the conditional cyclin A2 allele into a functionally null allele. (immune-source.com)

More abundant high molecular weight compounds, including boswellic acids, were present in Boswellia sacra essential oil prepared at 100 o C hydrodistillation. (biomedcentral.com)
P-TEFb in the cells is available in the type of distinctive molecular fat processes [11]. (healthyguide.info)

Many affected individuals have widespread disease at diagnosis, with involved regions often including multiple lymph nodes, the spleen, and, potentially, the bone marrow, the liver, and/or regions of the digestive (gastrointestinal) tract. (rarediseases.org)

There are two main types of lymphocytes: B-lymphocytes, which may produce specific antibodies to "neutralize" certain invading microorganisms, and T-lymphocytes, which may directly destroy microorganisms or assist in the activities of other lymphocytes. (rarediseases.org)

Whereas NETs have a protective role in host defense against pathogens, NETs have also been shown to be involved in the pathogenesis of various diseases including, thrombosis ( 2 ), cardiovascular diseases ( 3 , 4 ), auto-immune diseases ( 5 ) and sepsis ( 6 ). (frontiersin.org)
