Validation of suitable internal control genes for expression studies in aging. [PDF]

open access: yes, 2009
Quantitative data from experiments of gene expression are often normalized through levels of housekeeping genes transcription by assuming that expression of these genes is highly uniform. This practice is being questioned as it becomes increasingly clear

Enzymatic Properties of Recombinant Thermophilic Xylanase from Pseudothermotoga thermarum and Its Application in Beer Brewing [PDF]

open access: yesShipin Kexue, 2023
This study aimed to investigate the efficient expression of the xylanase gene Pthxyn of Pseudothermotoga thermarum and its application in beer brewing. The recombinant plasmid pET-20b-pthxyn was constructed and expressed in Escherichia coli.

Evaluation of reference genes for reverse transcription-quantitative PCR assays in organs of zebrafish exposed to glyphosate-based herbicide, Roundup

open access: yesAnimal, 2018
Roundup is a glyphosate-based herbicide (GBH) widely used in agriculture and may cause toxic effects in non-target organisms. Model organisms, as zebrafish, and analysis of gene expression by reverse transcription-quantitative PCR (RT-qPCR) could be used

Thrombospondin-3 augments injury-induced cardiomyopathy by intracellular integrin inhibition and sarcolemmal instability. [PDF]

open access: yes, 2019
Thrombospondins (Thbs) are a family of five secreted matricellular glycoproteins in vertebrates that broadly affect cell-matrix interaction. While Thbs4 is known to protect striated muscle from disease by enhancing sarcolemmal stability through increased

APLF and long non-coding RNA NIHCOLE promote stable DNA synapsis in non-homologous end joining

open access: yesCell Reports, 2023
Summary: The synapsis of DNA ends is a critical step for the repair of double-strand breaks by non-homologous end joining (NHEJ). This is performed by a multicomponent protein complex assembled around Ku70-Ku80 heterodimers and regulated by accessory ...

Friedmann Equation and Stability of Inflationary Higher Derivative Gravity [PDF]

open access: yes, 2001
Stability analysis on the De Sitter universe in pure gravity theory is known to be useful in many aspects. We first show how to complete the proof of an earlier argument based on a redundant field equation.

Effects of Nanoparticles on Double-Stranded RNA Stability in Corn Soil [PDF]

open access: yes, 2018
Double-stranded RNA (dsRNA) can potentially be used as a pesticide because these molecules trigger an immune response called RNA interference (RNAi). If the expression of essential genes matching the dsRNA sequence are silenced, then the pest dies.

Down-regulatory mechanism of mammea E/BB from Mammea siamensis seed extract on Wilms' Tumor 1 expression in K562 cells. [PDF]

open access: yes, 2016
BackgroundWilms' tumor 1 (WT1) is a biological marker for predicting leukemia progression. In this study, mammea E/BB, an active compound from Saraphi (Mammea siamensis) seed extract was examined for its effect on down-regulatory mechanism of WT1 gene ...

Validation of Suitable Reference Genes for Gene Expression Studies on Yak Testis Development

open access: yesAnimals, 2020
Testis has an important function in male reproduction. Its development is regulated by a large number of genes. The real-time reserve transcriptase-quantitative polymerase chain reaction (RT-qPCR) is a useful tool to evaluate the gene expression levels ...

Stability of constant retrial rate systems with NBU input* [PDF]

open access: yes, 2016
We study the stability of a single-server retrial queueing system with constant retrial rate, general input and service processes. First, we present a review of some relevant recent results related to the stability criteria of similar systems. Sufficient
