Methods Healthy term newborns in families with h/o allergy were enrolled after informed consent at the time of birth. This Indian birth cohort of 99 babies with family history of allergy (75) and no history of allergy (24) was studied for minimum of 1.5 years for development of allergies with evaluation of chemokine receptors (CXCR3, CCR5, CCR3, CCR4, CCR8). Markers of Th1 (IFNg, IL12p40) and T...

Recently, the human ether à go-go (eag) related gene 1 (hERG1) channel, a member of the voltage-dependent potassium channel (Kv) family, was determined to have a critical role in cancer cell proliferation, invasion, tumorigenesis and apoptosis. However, the expression levels and functions of hERG1 in osteosarcoma cells remain poorly characterized. In this study, hERG1 transcript and protein lev...

We performed dengue virus (DENV) serology and quantitative real-time pan-DENV reverse transcription-PCR (RT-PCR) on 186 sera of 171 patients returning from the tropics. DENV loads significantly decreased with increasing times of disease and were higher in immunoglobulin M-negative samples. In the first week of disease, pan-DENV RT-PCR is the test of choice.

Human enteric viruses are recognized as the main causes of food- and waterborne diseases worldwide. Sensitive and quantitative detection of human enteric viruses is typically achieved through quantitative RT-PCR (RT-qPCR). A nanofluidic real-time PCR system was used to develop novel high-throughput methods for qualitative molecular detection (RT-qPCR array) and quantification of human pathogeni...

Cytochrome P450 2C19 (CYP2C19) is the enzyme responsible for the metabolism of a number of drugs, including anticonvulsants and antidepressants. We have developed a semi-quantitative competitive RT-PCR assay to estimate the degree of expression of the full-length CYP2C19 message. This assay used a known quantity of internally deleted CYP2C19 RNA to quantitate the RT-PCR products of the CYP2C19 ...

A constitutive NOS complementary DNA (cDNA) was partially cloned by RT-PCR from the brain of a teleost, the Nile tilapia (Oreochromis niloticus), using degenerate primers against conserved regions of NOS. The predicted 206-long amino acid sequence showed a high degree of identity with other vertebrate neuronal NOS (nNOS) protein sequences. In addition, phylogenetic analysis revealed that Nile t...

Canavalia ensiformis (jackbean) seeds contain the proteins urease and canatoxin, a variant form of the jackbean urease. Here we have cloned a cDNA encoding another isoform of urease, called JBURE-II. This cDNA was obtained by RT-PCR using as template total RNA extracted from C. ensiformis tissues. Nucleotide sequence analysis showed that JBURE-II clones share 86% similarity with known jackbean ...

The use of molecular techniques such as quantitative RT-PCR depends on the quality of cellular RNA. In particular, RNA extraction from endoscopic biopsies is difficult with respect to yield, and especially integrity. Endoscopic biopsies taken from the gastric antrum, corpus and duodenum were subjected to various RNA extraction protocols, and the RNA was used for quantitative RT-PCR. The subsequ...
