Marine nematode taxonomy in the DNA age: the present and future of molecular tools to access their biodiversity [PDF]

, 2010
Molecular taxonomy is one of the most promising yet challenging fields of biology. Molecular markers such as nuclear and mitochondrial genes are being used in a variety of studies surveying marine nematode taxa.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Evaluation of COI and ITS2 sequences ability to distinguish Lysiphlebus fabarum and Lysiphlebus confusus (Hymenoptera: Aphidiidae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2012
All wasp species in the genus Lysiphlebus Förster are solitary endoparasitoids of aphids andconsidered a taxonomically difficult group. In this study a part of COI and ITS2 was used to distinguishtwo closely related species L.

Copy Number of Human Ribosomal Genes With Aging: Unchanged Mean, but Narrowed Range and Decreased Variance in Elderly Group

Frontiers in Genetics, 2018
Introduction: The multi-copied genes coding for the human 18, 5.8, and 28S ribosomal RNA (rRNA) are located in five pairs of acrocentric chromosomes forming so-called rDNA.

Following basal stem rot in young oil palm plantings [PDF]

, 2005
The PCR primer GanET has previously been shown to be suitable for the specific amplification of DNA from Ganoderma boninense. A DNA extraction and PCR method has been developed that allows for the amplification of the G.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

A binary vector for transferring genomic libraries to plants [PDF]

, 1986
The transformation of mutant plants with a complete recombinant library derived from wild-type DNA followed by assay of transformed plants for complementation of the mutant phenotype is a promising method for the isolation of plant genes.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Roles of ribosomal proteins in hematologic disorders and cancers: a review

Emergency and Critical Care Medicine, 2023
. Ribosomes are important organelles for synthesizing proteins in cells. They are composed of ribosomal RNA and more than 80 ribosomal proteins. It is well known that an essential function of ribosomal proteins is to participate in protein translation ...

DNA replication initiator Cdc6 also regulates ribosomal DNA transcription initiation [PDF]

Journal of Cell Science, 2016
ABSTRACT RNA-polymerase-I-dependent ribosomal DNA (rDNA) transcription is fundamental to rRNA processing, ribosome assembly and protein synthesis. However, how this process is initiated during the cell cycle is not fully understood.
