Scientists To Stop Tumor Growth In Future

Posted by Umar on March 15, 2011 · View Comments

A new study that took place a while ago regarding Tumor growth now suggests that combining two experimental anticancer peptide agents might simultaneously block formation of new tumor blood vessels while also inhibiting the growth of tumor cells. Researchers at the Ohio State University Comprehensive Cancer Center said that this early test of the two agents in a breast cancer model suggests that [...]

Scientists Explain Infection Causing Behavior of O157:H7 Strain

Scientists Explain Infection Causing Behavior of O157:H7 Strain

Posted by Umar on March 14, 2011 · View Comments

NIAID (National Institute of Allergy and Infectious Diseases) is a part of the National Institutes of Health. Scientists at the NIAID have now found a way to explain how theO157:H7 strain of Escherichia coli causes infections and how it manipulates the host immune response to grow vigorously. The bacterium secretes a protein called NleH1 that directs the host immune enzyme IKK-beta to alter specific [...]

Studies Show HER2-Positive Breast Cancer Requires Combined Targeted Therapies

Studies Show HER2-Positive Breast Cancer Requires Combined Targeted Therapies

Posted by Umar on March 8, 2011 · View Comments

The findings, reported in two papers in the Proceedings of the National Academy of Sciences (PNAS), suggest that upregulation of the HER3 receptor limits the effectiveness of two classes of targeted therapies (HER2- and PI3 kinase-targeted therapies). Therefore targeting HER3 together with these agents should improve their clinical utility. Around 25 percent of breast cancers have increased expression [...]

Colon Tumors Containing DNA Defects Are Likely To Recur Post-Surgery

Colon Tumors Containing DNA Defects Are Likely To Recur Post-Surgery

Posted by Umar on March 8, 2011 · View Comments

A randomized control trial in UK that was conducted over a span of 10 years by medical scientists has found that colon tumors containing defects in their DNA mismatch repair system are 50% less likely to recur after surgery relative to tumors in which DNA mismatch repair is normal. The study also suggests that patients with tumors showing mutation of the KRAS gene are more likely to re-grow compared [...]

Scientists Crack Code to Create Neurons Whose Early Death Causes Memory Loss

Scientists Crack Code to Create Neurons Whose Early Death Causes Memory Loss

Posted by Umar on March 7, 2011 · View Comments

Stem cells are biological cells found in all multicellular organisms, that can divide through mitosis and differentiate into diverse specialized cell types or can self renew to produce more stem cells. Researchers from NorthWestern University for the first time have transformed a human embryonic stem cell into a critical type of neuron that dies early in Alzheimer’s disease and is a major cause [...]
