MicroRNA 302a is a novel modulator of cholesterol homeostasis and atherosclerosis.

Objective: Macrophage foam cell formation is a key feature of atherosclerosis. Recent studies have shown that specific microRNAs (miRs) are regulated in modified low-density lipoprotein-treated macrophages, which can affect the cellular cholesterol homeostasis. Undertaking a genome-wide screen of miRs regulated in primary macrophages by modified low-density lipoprotein, miR-302a emerged as a potential candidate that may play a key role in macrophage cholesterol homeostasis.

Higher incidence of head and neck cancers among Vietnamese American men in California.

Background: Our aim was to determine the incidence rates of head and neck cancer in Vietnamese Californians compared with other Asian and non-Asian Californians.

Methods: Age-adjusted incidence rates of head and neck cancer between 1988 and 2004 were computed for Vietnamese Californians compared with other racial/ethnic groups by time period, ethnicity, neighborhood-level socioeconomic status (SES), and sex using data from the population-based California Cancer Registry (CCR). Data by smoking and alcohol status were tabulated from the California Health Interview Survey.
