Fidelity of DNA polymerases in the detection of intraindividual variation of mitochondrial DNA

Mitochondrial DNA. Part B. Resources, 2020
Here we investigated the consequences of PCR amplification errors in the identification of intraindividual mtDNA variation. The bumblebee Bombus morio was chosen as model for the COI gene amplification tests with two DNA polymerases (Taq and Q5 ...

Impact of metal oxide nanoparticles on in vitro DNA amplification [PDF]

PeerJ, 2019
Polymerase chain reaction (PCR) is used as an in vitro model system of DNA replication to assess the genotoxicity of nanoparticles (NPs). Prior results showed that several types of NPs inhibited PCR efficiency and increased amplicon error frequency.

Erythropoietin modulates hepatic inflammation, glucose homeostasis, and soluble epoxide hydrolase and epoxides in high‐fat diet‐induced obese mice

FEBS Open Bio, EarlyView.
Erythropoietin administration suppresses hepatic soluble epoxide hydrolase (sEH) expression, leading to increased CYP‐derived epoxides. This is associated with a shift in hepatic macrophage polarization characterized by reduced M1 markers and increased M2 markers, along with reduced hepatic inflammation, suppressed hepatic lipogenesis, and attenuated ...

The reproducibility of RAPD profiles: Effects of PCR components on RAPD analysis of four centaurium species [PDF]

Archives of Biological Sciences, 2012
Random amplified polymorphic DNA (RAPD) analysis is a simple and reliable method used to detect DNA polymorphism. Several factors can affect the amplification profiles, thereby causing false bands and non-reproducibility of the assay.

Taq polymerase contains bacterial DNA of unknown origin

Molecular and Cellular Probes, 1990
The polymerase chain reaction (PCR) was carried out with the highly conserved E. coli ribosomal RNA gene sequences 1376-1395 and 1521-1540. Using these primers and reaction conditions specified by the manufacturer(s), a 165 bp fragment was synthesized using Taq polymerase from three different sources in the absence of any added template.

A Human Kidney Tubuloid Model of Repeated Cisplatin‐Induced Cellular Senescence and Fibrosis for Drug Screening

Advanced Healthcare Materials, EarlyView.
Replicating aging and senescence‐related pathophysiological responses in kidney organoids remains a significant challenge. Human adult renal tubular organoid, tubuloids, are successfully developed recapitulating cellular senescence that is the central pathophysiological mechanism of chronic kidney disease (CKD).

Effect of Agitation on Taq DNA Polymerase Production by Escherichia Coli in Bioreactor

Chemical Engineering Transactions, 2022
The Taq DNA polymerase is an important protein used during PCR (Polymerase chain reaction), a technique widely used today. The production of this enzyme in bioreactors make possible to improve efficiency, to reduce production time, to increase production

Living Materials Approach for In Situ Bio‐Polymers Production Using Bacillus Paralicheniformis in Microneedles

Advanced Healthcare Materials, EarlyView.
Dissolvable microneedle (MN) device containing Bacillus paralicheniformis. The polymeric matrix encapsulates and protects the bacteria, preserving their viability while enabling in situ production and release of γ‐polyglutamic acid. The bacteria are delivered into the skin via 500 µm‐long microneedles, and remain detectable on the skin 24 h post ...

Phase‐Separation of YAP Mediates AJUBA Super Enhancer Activation to Promote Aberrant Mitosis in Breast Cancer

Advanced Science, EarlyView.
YAP undergoes phase separation to activate the AJUBA super‐enhancer, driving aberrant mitosis through spindle checkpoint dysregulation in breast cancer. This study uncovers a mechanistic link between YAP condensates, super‐enhancer activation, and aneuploidy formation.
