- Many long-term prospective studies have reported on associations of cardiovascular diseases with circulating lipid markers and/or inflammatory markers. Studies have not, however, generally been designed to provide reliable estimates under different circumstances and to correct for within-person variability. The Emerging Risk Factors Collaboration has established a central database on over 1.1 million participants from 104 prospective population-based studies, in which subsets have information on lipid and inflammatory markers, other characteristics, as well as major cardiovascular morbidity and cause-specific mortality. Information on repeat measurements on relevant characteristics has been collected in approximately 340,000 participants to enable estimation of and correction for within-person variability. Re-analysis of individual data will yield up to approximately 69,000 incident fatal or nonfatal first ever major cardiovascular outcomes recorded during about 11.7 million person years at risk. The primary analyses will involve age-specific regression models in people without known baseline cardiovascular disease in relation to fatal or nonfatal first ever coronary heart disease outcomes. This initiative will characterize more precisely and in greater detail than has previously been possible the shape and strength of the age- and sex-specific associations of several lipid and inflammatory markers with incident coronary heart disease outcomes (and, secondarily, with other incident cardiovascular outcomes) under a wide range of circumstances. It will, therefore, help to determine to what extent such associations are independent from possible confounding factors and to what extent such markers (separately and in combination) provide incremental predictive value.

- Oculofaciocardiodental (OFCD) syndrome is an X-linked male lethal condition encompassing cardiac septal defects, as well as ocular and dental anomalies. The gene mutated in OFCD syndrome, the BCL-6 corepressor (BCOR), is part of a transcriptional repression complex whose transcriptional targets remain largely unknown. We reviewed cases of OFCD syndrome and identified patients exhibiting defective lateralization including dextrocardia, asplenia and intestinal malrotation, suggesting that BCOR is required in normal laterality determination. To study the function of BCOR, we used morpholino oligonucleotides (MOs) to knockdown expression of xtBcor in Xenopus tropicalis, thus creating an animal model for OFCD syndrome. The resulting tadpoles had cardiac and ocular features characteristic of OFCD syndrome. Reversed cardiac orientation and disorganized gut patterning were seen when MOs were injected into the left side of embryos, demonstrating a left-sided requirement for xtBcor in lateral determination in Xenopus. Ocular defects displayed no left-right bias and included anterior and posterior segment disorders such as microphthalmia and coloboma. Expression of xtPitx2c was shown to be downregulated when xtBcor was depleted. This identifies a pathway in which xtBcor is required for lateral specification, a process intrinsically linked to correct cardiac septal development.
