The molecular basis of nucleotide recognition for T7 DNA polymerase

, 2008
textDNA replication demands extraordinary specificity and efficiency of catalysis from a DNA polymerase. Previous studies on several DNA polymerases suggested that a rate-limiting conformational change preceding chemistry accounts for the high ...

Escherichia coli σ70 senses sequence and conformation of the promoter spacer region [PDF]

, 2010
In bacteria, promoter identification by RNA polymerase is mediated by a dissociable p factor. The housekeeping σ70 factor of Escherichia coli recognizes two well characterized DNA sequence elements, known as the ‘-10’ and ‘-35’ hexamers.

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Identification of human papillomavirus DNA in cutaneous lesions of Cowden syndrome [PDF]

, 2003
Background: Cowden syndrome (CS) or multiple hamartoma syndrome is a cancer-associated genodermatosis inherited in an autosomal dominant pattern. One of the diagnostic criteria is facial papules which are felt to be trichilemmomas, benign hair follicle ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Function of the upstream activating factor in chromatin structure organization and transcriptional regulation at the yeast ribosomal DNA

, 2010
Chromatin is the template of all processes involved in DNA metabolism in the eukaryotic cell. Accordingly, chromatin is a dynamic structure which changes in its composition and posttranslational modification correlating with the functional state of a ...

Noninvasive prenatal diagnosis of fetal RhD status using cell-free fetal DNA in maternal plasma with TaqMan® real-time PCR assay [PDF]

, 2007
Prenatal diagnosis is now part of established obstetric practice in many countries. However, conventional methods of prenatal diagnosis of obtaining fetal tissues for genetic analysis, including amniocentesis and chorionic villus sampling, are invasive

Liquid biopsy‐based diagnostic evaluation of hypermethylated CpG sites for ovarian cancer diagnosis

Molecular Oncology, EarlyView.
This schematic outlines the workflow from biomarker identification to duplex MethyLight assay validation for epithelial ovarian cancer diagnosis using cfDNA‐based liquid biopsy. Initial screening of hypermethylated CpG candidates (cg02957270, cg10061138 cg00480298, COL2A1) was performed in tissue using ARMS‐PCR, COBRA, qPCR and image analysis. Selected

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.
