Urine Specimens from Pregnant and Nonpregnant Women Inhibitory to Amplification of \u3cem\u3eChlamydia trachomatis\u3c/em\u3e Nucleic Acid by PCR, Ligase Chain Reaction, and Transcription-Mediated Amplification: Identification of Urinary Substances Associated with Inhibition and Removal of Inhibitory Activity [PDF]

open access: yes, 1998
The presence of endogenous amplification inhibitors in urine may produce false-negative results for the detection of Chlamydia trachomatis nucleic acids by tests such as PCR, ligase chain reaction (LCR), and transcription-mediated amplification (TMA ...

Characterization of a temperature-sensitive DNA ligase from Escherichia coli [PDF]

open access: yes, 2004
DNA ligases are essential enzymes in cells due to their ability to join DNA strand breaks formed during DNA replication. Several temperature-sensitive mutant strains of Escherichia coli, including strain GR501, have been described which can be ...

Kinetic Mechanism of Human DNA Ligase I Reveals Magnesium-dependent Changes in the Rate-limiting Step That Compromise Ligation Efficiency*

open access: yesJournal of Biological Chemistry, 2011
DNA ligase I (LIG1) catalyzes the ligation of single-strand breaks to complete DNA replication and repair. The energy of ATP is used to form a new phosphodiester bond in DNA via a reaction mechanism that involves three distinct chemical steps: enzyme ...

FBXO44 Regulates FOXP1 Degradation Through AURKA‐Dependent Phosphorylation to Promote Colorectal Cancer Progression

open access: yesAdvanced Science, EarlyView.
FBXO44 promotes colorectal cancer progression by targeting FOXP1 for ubiquitin‐mediated degradation. This study reveals a phosphorylation‐dependent mechanism involving AURKA and highlights the FBXO44/FOXP1/Cyclin E2 axis as a potential therapeutic target in colorectal cancer.

The Human Adenovirus Type 5 E4orf6/E1B55K E3 Ubiquitin Ligase Complex Can Mimic E1A Effects on E2F

open access: yesmSphere, 2016
The human adenovirus E4orf6/E1B55K E3 ubiquitin ligase is well known to promote viral replication by degrading an increasing number of cellular proteins that inhibit the efficient production of viral progeny.

Obesity‐Associated TRIM15 Promotes the Proliferation of Esophageal Adenocarcinoma Through the YY2/FOXRED1 Axis

open access: yesAdvanced Science, EarlyView.
The study identifies TRIM15 as a key driver in the development of obesity‐associated esophageal adenocarcinoma (EAC). Mechanistically, TRIM15 degrades YY2 through the proteasome pathway, suppressing FOXRED1 transcription and ultimately accelerating tumor proliferation.

DNA 3 '-Phosphatase Activity Is Critical for Rapid Global Rates of Single-Strand Break Repair following Oxidative Stress [PDF]

open access: yes, 2009
Oxidative stress is a major source of chromosome single-strand breaks (SSBs), and the repair of these lesions is retarded in neurodegenerative disease. The rate of the repair of oxidative SSBs is accelerated by XRCC1, a scaffold protein that is essential

TRIM30α Is a Negative-Feedback Regulator of the Intracellular DNA and DNA Virus-Triggered Response by Targeting STING.

open access: yesPLoS Pathogens, 2015
Uncontrolled immune responses to intracellular DNA have been shown to induce autoimmune diseases. Homeostasis regulation of immune responses to cytosolic DNA is critical for limiting the risk of autoimmunity and survival of the host. Here, we report that
