Extraction of total RNA from single-oocytes and single-cell mRNA sequencing of swine oocytes

open access: yesBMC Research Notes, 2018
Objective Analyses of single oocytes are essential for a fine dissection of molecular features governing developmental competence. We adapted the phenol–chloroform procedure for the purification of total RNA from single oocytes. Results Key modifications

Glutathione reductase-catalyzed cascade of redox reactions to bioactivate potent antimalarial 1,4-naphthoquinones--a new strategy to combat malarial parasites. [PDF]

open access: yes, 2011
Our work on targeting redox equilibria of malarial parasites propagating in red blood cells has led to the selection of six 1,4-naphthoquinones, which are active at nanomolar concentrations against the human pathogen Plasmodium falciparum in culture and ...

Molecular Identification of the Nematode Eustrongylides ignotus in Mandarin Fish, Siniperca chuatsi

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Mandarin fish (Siniperca chuatsi) is a high‐value economic freshwater fish in China; however, the frequent occurrence of diseases threatens its production. To this end, we explored the impact of a nematode parasite newly found in the abdomen of mandarin fish collected from Pudong, Shanghai, China.

Viability of Self‐Taken Vaginal Swab Samples for RNA‐Based Biomarker Analysis in Cervical Disease

open access: yesJournal of Medical Virology, Volume 97, Issue 12, December 2025.
ABSTRACT High risk human papillomaviruses (hrHPVs) cause most cervical cancers. Cervical screening programmes aim to identify precancerous disease using detection of hrHPV nucleic acid using clinician‐taken liquid‐based cytology (LBC) samples, or increasingly, self‐taken samples (STSs).

Repeated reunions and splits feature the highly dynamic evolution of 5S and 35S ribosomal RNA genes (rDNA) in the Asteraceae family

open access: yesBMC Plant Biology, 2010
Background In flowering plants and animals the most common ribosomal RNA genes (rDNA) organisation is that in which 35S (encoding 18S-5.8S-26S rRNA) and 5S genes are physically separated occupying different chromosomal loci.

Isolation of high quality RNA from soil-grown Ilex paraguariensis roots suitable for next-generation sequencing and gene expression analyses [PDF]

open access: yes, 2017
Extraction of high quality RNA is a prerequisite for downstream application in functional genomics analyses. However, the extraction and purification of pure nucleic acids from root tissues is generally difficult due to the high concentration of ...

Patterns and regulation of ribosomal RNA transcription in Borrelia burgdorferi

open access: yesBMC Microbiology, 2011
Background Borrelia burgdorferi contains one 16S and two tandem sets of 23S-5S ribosomal (r) RNA genes whose patterns of transcription and regulation are unknown but are likely to be critical for survival and persistence in its hosts. Results RT-PCR of B.

Reduced ribosomal RNA expression and unchanged ribosomal DNA promoter methylation in oral squamous cell carcinoma

open access: yesMolecular Genetics & Genomic Medicine, 2019
Background Ribosomal RNA (rRNA) consists of four non‐coding RNAs, the 28S, 5.8S, 18S, and 5S rRNA. Abnormal expression of rRNA has been found in multiple tumors, and the methylation of rDNA promoter may affect rRNA expression as an epigenetic regulatory ...

Conservation and loss of ribosomal RNA gene sites in diploid and polyploid Fragaria (Rosaceae)

open access: yesBMC Plant Biology, 2011
Background The genus Fragaria comprises species at ploidy levels ranging from diploid (2n = 2x = 14) to decaploid (2n = 10x = 70). Fluorescence in situ hybridization with 5S and 25S rDNA probes was performed to gather cytogenetic information that ...
