Unexpressed But Indispensable -- The DNA Sequences That Control Development
Amidst the hoopla over the exact number of genes we have in our genome—more than a fruitfly, fewer than a rice plant—a more fundamental genetic truth has often been obscured. The expression of 20,000?0,000 genes is under the control of an uncounted host of non-coding sequences, which bind transcription factors and thereby regulate when and where genes are expressed. Unlike coding sequences, whose...Growth factor-promoting angiogenesis expressed in tumor cells and normal neurons
Scientists have discovered that a stem cell factor overexpressed both in brain tumor cells and in neurons following brain injury promotes tumor survival by inducing angiogenesis. The research study, published in the April issue of Cancer Cell, examines the interaction between tumor cells and surrounding tissues and may have substantial significance for design of more effective therapeutics for on...Identification of Differentially Expressed Gene Products with the CastAway System*
CastAway precast gels for fast analysis of RAP-PCR and differentialdisplay Stratagene Cloning Systems, Inc. Stratagenes new CastAway precast sequencing gels were used to detectand isolate differentially expressed gene products amplified by the RNAarbitrarily primed polymerase chain reaction (R...Outwardly Expressed Anger Affects Some Women’s Heart Arterie
While previous studies have shown that anger and hostility, in and of themselves, can increase risk of heart disease in men, little of the research has included women. // Results of a new study, conducted exclusively with female subjects, suggest that anger and hostility alone are not predictive for coronary artery disease in women, but women who outwardly express anger may be at incr...Concern Expressed Over Poor Quality Bird Flu Vaccine Used in Nigeria
Commericail poultry farmers are going for vaccination of their stock against bird flu, but use of inferior quality vaccination is fraught with great risks, experts warn. Nigeria to date has officially banned the use of vaccines to tackle H5N1.Through culling, quarantine, disinfecting and surveillance of affected areas, Nigeria has achieved good success in reducing the disease inciden...
