Researchers discover inherited mutation for leukemia

...ivity. Furthermore, a second kind of change occurs later that turns the gene off altogether, leading to leukemia. This latter alteration is a chemical change that is not inherited. The findings could help identify people at risk for chronic leukemia, but they also may provide new insights into the proc...

Pregnant mom's exposure to flu vaccine kick-starts fetal immune system

...t of allergic sensitivity (e.g. eczema and asthma) later in an infant’s life. However this hypothesis has remained controversial because of an inability to detect antigen-specific T cells in cord blood. Recently, a newly developed technique known as MHC tetramer staining has facilitated the detection of an...

The DNA further suggests that no later than forty thousand years ago, one of the groups died out, leaving only the second alive at the time of the mammoth’s last gasp. “At a time when we should be very concerned about the potential extinction of many existing large mammals, studying th...

Sun exposure early in life linked to specific skin cancer gene mutation

...S gene, was found in patients who had sun exposure later in life (between ages 50 to 60 years old). The results indicate that different subtypes of melanoma are associated with different risk factors "The findings suggest that melanoma subtypes have different causes. This is important for learning more ...

Researchers shed light on shrinking of chromosomes

...’s lab, “we think that the ‘super condensation’ at later stages helps to disentangle such chromosomes and acts as a back-up mechanism to rescue separation defects.” The EMBL researchers found that an enzyme called Aurora kinase is crucially involved in this process. Blocking this enzyme abolishes late co...

While this study may provide a signal of the effect of IVIG therapy to clinical outcomes, further investigation in larger controlled and longer-term trials will be needed to definitively demonstrate whether IVIG is useful in treating Alzhe...

The extra hormone affects the back patterns of lizards that hatch from those eggs, cre...

Komorowski noted, however, that although the lower-fat milk may be healthier, it will be interesting to see how much milk th...

The researchers suggested that ATM had been displaced or moved so that the repair proteins could gain access to the damaged DNA site. ...
