1.N-terminal pro-B-type natriuretic peptide, left ventricular mass, and incident heart failure: Multi-Ethnic Study of Atherosclerosis.
Choi EY1, Bahrami H, Wu CO, Greenland P, Cushman M, Daniels LB, Almeida AL, Yoneyama K, Opdahl A, Jain A, Criqui MH, Siscovick D, Darwin C, Maisel A, Bluemke DA, Lima JA. Circ Heart Fail. 2012 Nov;5(6):727-34. doi: 10.1161/CIRCHEARTFAILURE.112.968701. Epub 2012 Oct 2.
BACKGROUND: Elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) is associated with clinically overt heart failure (HF). However, whether it provides additive prognostic information for incident HF beyond traditional risk factors and left ventricular (LV) mass index among multi-ethnic asymptomatic individuals has not yet been determined. We studied the associations of plasma NT-proBNP and magnetic resonance imaging defined LV mass index with incident HF in an asymptomatic multi-ethnic population.
2.Molecular biomarkers and classification models in the evaluation of the prognosis of colorectal cancer.
Sideris M1, Papagrigoriadis S. Anticancer Res. 2014 May;34(5):2061-8.
Colorectal cancer (CRC) is the second leading cause of cancer-related death. Despite the progress that has been made towards the identification of the molecular mechanisms involved in CRC, currently there are many unclear points. The current opinion is that microsatellite instability (MSI), CpG island methylator phenotype (CIMP) and chromosomal instability (CIN) seem to play a significant role. MSI is related to point mutations in defect mismatch repair system of DNA. There are two well-established MSI phenotypes: MSI-high (MSI-H) and MSI-low (MSI-L or MSS). CIN refers to a different cellular event which originates from the presence of an abnormal chromosome complement or number. CIMP is the third most commonly involved event, and is defined by widespread methylation of CpG islands of suppressor promoters, with two phenotypes: CIMP-high and CIMP-low which interact with MSI or CIN status V-raf murine sarcoma viral oncogene homolog B (BRAF) is a serine-threonine protein kinase that acts as a downstream effector of the Kirsten rat sarcoma viral oncogene homolog (KRAS) pathway.
3.Pro-apoptotic low-density lipoprotein subfractions in type II diabetes.
Yang CY1, Chen HH, Huang MT, Raya JL, Yang JH, Chen CH, Gaubatz JW, Pownall HJ, Taylor AA, Ballantyne CM, Jenniskens FA, Smith CV. Atherosclerosis. 2007 Aug;193(2):283-91. Epub 2006 Oct 9.
OBJECTIVE: To test the hypothesis that differences in subfractions of circulating lipoproteins between diabetic and non-diabetic subjects exist and might contribute to the increased risk for atherosclerosis in type II diabetics.
