Recent sequence variation in probe binding site affected detection of respiratory syncytial virus group B by real-time RT-PCR [PDF]

, 2017
Background Direct immuno-fluorescence test (IFAT) and multiplex real-time RT-PCR have been central to RSV diagnosis in Kilifi, Kenya. Recently, these two methods showed discrepancies with an increasing number of PCR undetectable RSV-B viruses ...

Evaluation of the Effects of DNase Treatment on Signal Specificity in RT-PCR and In Situ RT-PCR [PDF]

BioTechniques, 1998
In this study, the effects of DNase treatment on the specificity of reverse transcription (RT)-PCR have been investigated on different samples, containing RNA, DNA, DNA/RNA and DNA/cDNA. This was to evaluate the possibilities of getting specific results in a direct in situ RT-PCR.

In-House RT-PCR Assay for Detection of Human Immunodeficiency Virus Type 1 Infection [PDF]

, 2009
Serologic assays are commonly used for screening (ELISA) and for confirmation (Western blot) of HIV-1 infection; however, both assays have potentially yielded the false-positive or false-negative results.

STAT3 expression is reduced in cardiac pericytes in HFpEF and its loss reduces cellular adhesion and induces pericyte senescence

FEBS Letters, EarlyView.
Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.

A coiled‐coil domain triggers oligomerization of MmpL10, the mycobacterial transporter of trehalose polyphleate precursor

FEBS Letters, EarlyView.
Most MmpLs transport lipids and glycolipids of the complex mycomembrane of mycobacteria. This study shows that MmpL10 from Mycobacterium smegmatis, the transporter of the trehalose polyphosphate precursor, harbors a coiled‐coil‐like extension. Biochemical and electron microscopy studies demonstrate that the coiled‐coil enables MmpL10 to trimerize.

Acute promyelocytic leukemia: the study of t(15;17) translocation by fluorescent in situ hybridization, reverse transcriptase-polymerase chain reaction and cytogenetic techniques [PDF]

, 2001
Acute promyelocytic leukemia (AML M3) is a well-defined subtype of leukemia with specific and peculiar characteristics. Immediate identification of t(15;17) or the PML/RARA gene rearrangement is fundamental for treatment.

RT-PCR Without RNA Isolation

BioTechniques, 1996
Reverse transcription-PCR (RT-PCR) has traditionally required time-consuming RNA extraction and purification. This report demonstrates that one can completely avoid the RNA extraction step in RT-PCR by basing the comparison of samples on cell number rather than micrograms of total RNA. A new method for lysing cells while preserving RNA is described. RT-

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells

Molecular Oncology, EarlyView.
In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

Single-and multiple viral respiratory infections in children: Disease and management cannot be related to a specific pathogen [PDF]

, 2017
Background: The number of viral pathogens associated with pediatric acute respiratory tract infection (ARI) has grown since the introduction of reverse transcription real-time polymerase chain reaction (RT-PCR) assays.
