A study found that the MDR1 gene variation is associated with immune recovery after HIV treatment. The polymorphism MDR1 3435C/T predicts improved CD4-cell count recovery. This suggests P-glycoprotein plays a crucial role in antiretroviral drug absorption.
A study of 96 elderly women found that high caffeine intake (over 300mg/day) accelerates bone loss, especially in those with the tt VDR genotype. Moderate caffeine consumption is not linked to increased bone loss, and doctors recommend adequate calcium and moderate caffeine for their patients.
A study found that a specific mutation in the human MDR1 gene affects P-glycoprotein expression, leading to decreased effectiveness of HIV-1 protease inhibitors in West Africans and African Americans compared to Caucasians. This could have significant implications for drug treatment in these populations.
A study of 286 patients with mild to moderate Alzheimer's disease found that treatment response to Aricept was not predicted by ApoE4 genotype or gender. Patients treated with Aricept showed significant improvements in global function and cognition, while those on placebo experienced decline.
Research reveals a strong interaction between neuroticism and the serotonin transporter gene in influencing cigarette smoking behavior. Individuals with poorly expressed serotonin transporter genotypes and high levels of neuroticism face significant challenges in quitting smoking. This study suggests personalized approaches to smoking ...
A study found that genetic variations can cause individuals to be more resistant to a cholesterol-lowering diet or at greater cardiovascular risk from a high-fat diet. Apolipoprotein B gene polymorphisms were associated with increased plasma total cholesterol concentrations in certain genotypes.
The study found that people with the 4/4 variant are 15 times more likely to develop Alzheimer's disease than those with the 3/3 variant. In contrast, individuals with the 2/3 genotype appear to be protected from developing AD due to the presence of the protective 2 allele.
