Viral DNA sequence a possible trigger for breast cancer

A small sequence of DNA in the envelope (Env) protein of a mouse breast tumor virus (called MMTV) can transform breast cells into cancer cells, according to a study by Katz et al. in the February 7 issue of The Journal of Experimental Medicine. The ability of this motif to transform cells single-handedly suggests that viral infection may be an important and previously unrecognized trigger for bre...

GATA: a graphic alignment tool for comparative sequence analysis

Sometimes apotential target for a drug seems very promising on paper; things areoften very different in reality. Its the case of telomerase inhibitorsto treat cancer; they are supposed to strip the "immortal" (able todivide indefinitely) aspect of cancer cells. Yet, something in the cellseems to block their function, preventing them to inhibit completelythe...

Found: Missing sequence of the human Y chromosome

Scientists report today in the journal GenomeResearch that they have successfully cloned and characterized apreviously intractable DNA sequence: a 554-kilobase-pair genomicsegment near the centromere of the human Y chromosome. This sequencecontains eight putatively active genes that could be implicated insex-associated height differences and gonadal tumor development. Thispericentrom...

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...

Multiple Campylobacter Genomes Sequenced

In 1995, the first complete bacterial genome sequence was published. Now, nearly 200 bacterial genomes have been completed, and a new one hits the scientific press most weeks. This burgeoning industry is not just scientific “stamp collecting,?however. Having all these genome sequences may provide useful clues about why some bacteria cause human disease, how to control their spread, and how to tre...

Psychological consequence of terrorist attacks

The Terrorist attack on the World Trade Centre and the Pentagon could affect the mental health of Americans over coming weeks and months. As the dust settles over New York and Washington, psychiatrists warn that people will start to feel the full psychological impact of the disaster. Keeping busy and trying to get the cities back to normal keeps anxiety and grief at bay. And the sheer scale of th...

Yet Another Harmful Consequence Of Smoking

Moms-to-be have one more good reason not to smoke. According to a recent study researchers find smoking during the early months // of pregnancy increases the risk of having a baby with a cleft lip.

The Consequences Of Stopping Physical Activity

A new study shows in as little as two days of physical inactivity, the body's efficient use of insulin may decrease, leading to diabetes and other related diseases.// Researchers conducted a study in rats and found insulin sensitivity decreased the longer the rats stayed inactive.

WHO Steps Up To Create A Public Awareness About The Consequences Of Exposure To Radon

Radon is a chemically inert, naturally occurring radioactive gas// without odour, colour or taste. Radon is a natural radioactive gas that emanates from the ground into the air. Radon gas in the air is present worldwide, its concentration depending on the highly variable uranium content of the soil. Radon gas escapes easily from the ground into the air and emits heavily ionizing radiation called...

Heart damage a consequence of Atkins’ Die
