MicroRNAs are increasingly reported as tumour suppressors that regulate gene expression after transcription. Our results demonstrated that miR-4295 is overexpression in glioma tissues and its level is significantly correlated with clinical stage. We also found that miR-4295 inhibited the cell G0/G1 arrest and apoptosis leading to promoted cell proliferation and activity. The murine modelling st...

The Runt-related transcription factors (RUNX), mitogen-activated protein kinase (MAPK) 1 and eukaryotic translation initiation factor 4E (eIF4E) are potentially involved in tumorigenesis. We evaluated genetic variation in RUNX1 (40 tagSNPs), RUNX2 (19 tagSNPs), RUNX3 (9 tagSNPs), MAPK1 (6 tagSNPs), eIF4E (3 tagSNPs), eIF4EBP2 (2 tagSNP) and eIF4EBP3 (2 tagSNPs) to determine associations with co...

DNA mismatch repair suppresses gastrointestinal tumorgenesis. Four mammalian E. coli MutL homologues heterodimerize to form three distinct complexes: MLH1/PMS2, MLH1/MLH3, and MLH1/PMS1. To understand the mechanistic contributions of MLH3 and PMS2 in gastrointestinal tumor suppression, we generated Mlh3(-/-);Apc(1638N) and Mlh3(-/-);Pms2(-/-);Apc(1638N) (MPA) mice. Mlh3 nullizygosity significan...

The RUNX transcription factors are important regulators of linage-specific gene expression in major developmental pathways. Recently, we demonstrated that Runx3 is highly expressed in developing cranial and dorsal root ganglia (DRGs). Here we report that within the DRGs, Runx3 is specifically expressed in a subset of neurons, the tyrosine kinase receptor C (TrkC) proprioceptive neurons. We show...

Epstein-Barr virus nuclear antigen 3C (EBNA3C) repression of CDKN2A p14(ARF) and p16(INK4A) is essential for immortal human B-lymphoblastoid cell line (LCL) growth. EBNA3C ChIP-sequencing identified >13,000 EBNA3C sites in LCL DNA. Most EBNA3C sites were associated with active transcription; 64% were strong H3K4me1- and H3K27ac-marked enhancers and 16% were active promoters marked by H3K4me3 an...

Exposure to traffic-related pollution during childhood has been associated with asthma exacerbation, and asthma incidence. The objective of the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS) is to determine if the development of allergic and respiratory disease is associated with exposure to diesel engine exhaust particles. A detailed receptor model analyses was undertaken by app...

During development, the pancreatic endocrine cells are specified within the epithelium. They will subsequently delaminate and migrate out of the epithelium in order to form the islets. Neurogenin3 (Ngn3) is a bHLH transcription factor that is responsible for differentiation of all endocrine cell types, but whether or not it has a role in their migration is still an open question. By using the c...

Promoter DNA methylation status of six genes in samples derived from 27 bronchial epithelial cells and matching blood samples from 22 former/current smokers and five nonsmokers as well as 49 primary non-small cell lung cancer samples with corresponding blood controls was determined using methylation-specific PCR (MSP). Lung tumor tissues showed a significantly higher frequency of promoter DNA m...
