Gene-specific monitoring of T7-based RNA amplification by real-time quantitative PCR

open access: yesBioTechniques, 2003
T7-based RNA amplification is applied when there is insufficient RNA. The overall extent of amplification can be measured spectrophotometrically (i.e., quantifying RNA yields), but this measurement does not provide information about the RNA amplification

A pepper MSRB2 gene confers drought tolerance in rice through the protection of chloroplast-targeted genes. [PDF]

open access: yesPLoS ONE, 2014
The perturbation of the steady state of reactive oxygen species (ROS) due to biotic and abiotic stresses in a plant could lead to protein denaturation through the modification of amino acid residues, including the oxidation of methionine residues ...

A family with acute intermittent porphyria [PDF]

open access: yes, 2008
Porphyrias are inherited defects in heme metabolism that result in excessive secretion of porphyrins and porphyrin precursors. Porphyrias can be classified into acute, (neuropsychiatric), cutaneous and mixed forms.

Quantitative Real-Time RT-PCR Using Hybridization Probes and Imported Standard Curves for Cytokine Gene Expression Analysis

open access: yesBioTechniques, 2002
Quantitative real-time or kinetic RTPCR is increasingly used for the quantification of specific mRNA targets, especially in clinical applications. To quantify the mRNA of cytokines and their receptors, which play important roles in the pathogenesis of ...

Nitric oxide in fungi: is there NO light at the end of the tunnel? [PDF]

open access: yes, 2016
Nitric oxide (NO) is a remarkable gaseous molecule with multiple and important roles in different organisms, including fungi. However, the study of the biology of NO in fungi has been hindered by the lack of a complete knowledge on the different ...

Hepatocyte Transplantation Ameliorates the Metabolic Abnormality in a Mouse Model of Acute Intermittent Porphyria

open access: yesCell Transplantation, 2014
Acute intermittent porphyria (AIP) is an autosomal dominant disorder characterized by insufficient porphobilinogen deaminase (PBGD) activity. When hepatic heme synthesis is induced, porphobilinogen (PBG) and 5-aminolevulinic acid (ALA) accumulate, which ...

Development of highly sensitive and specific mRNA multiplex system (XCYR1) for forensic human body fluids and tissues identification. [PDF]

open access: yesPLoS ONE, 2014
The identification of human body fluids or tissues through mRNA-based profiling is very useful for forensic investigations. Previous studies have shown mRNA biomarkers are effective to identify the origin of biological samples. In this study, we selected

Transient and intensive pharmacological immunosuppression fails to improve AAV-based liver gene transfer in non-human primates [PDF]

open access: yes, 2012
BACKGROUND: Adeno-associated vectors (rAAV) have been used to attain long-term liver gene expression. In humans, the cellular immune response poses a serious obstacle for transgene persistence while neutralizing humoral immunity curtails re ...

The 5' untranslated region of the I factor, a long interspersed nuclear element-like retrotransposon of Drosophila melanogaster, contains an internal promoter and sequences that regulate expression [PDF]

open access: yes, 1993
The I-R system of hybrid dysgenesis in Drosophila melanogaster is controlled by a long interspersed nuclear element-like retroposon, the I factor.

PORPHOBILINOGEN DEAMINASE AND ADENOSINE DEAMINASE ACTIVITY AS A POSSIBLE DIAGNOSTIC AID IN LYMPHATIC LEUKEMIAS [PDF]

open access: yesMedical Journal Armed Forces India, 1999
It has been demonstrated recently that in addition to morphologic and immunologic methods, enzyme characterisation of lymphoid cells is useful in the study and classification of lympho proliferative disorders. Heme biosynthetic pathway and purine metabolism are reported to be disturbed in such patients, this study was an attempt to estimate two enzymes
