Differentiation and genetic analysis of Rhodnius prolixus and Rhodnius colombiensis by rDNA and RAPD amplification

open access: yesMemorias do Instituto Oswaldo Cruz, 2001
Domiciliated Rhodnius prolixus and sylvatic R. colombiensis were analyzed in order to confirm their genetic divergence and verify the risk that the latter represents in the domiciliation process, and to provide tools for identifying the sources of ...

Tempo and mode of gene duplication in mammalian ribosomal protein evolution. [PDF]

open access: yesPLoS ONE, 2014
Gene duplication has been widely recognized as a major driver of evolutionary change and organismal complexity through the generation of multi-gene families.

Modules identification in gene positive networks of hepatocellular carcinoma using pearson agglomerative method and Pearson cohesion coupling modularity [PDF]

open access: yes, 2012
In this study, a gene positive network is proposed based on a weighted undirected graph, where the weight represents the positive correlation of the genes.

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

open access: yesFEBS 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.

RPG: the Ribosomal Protein Gene database [PDF]

open access: yesNucleic Acids Research, 2004
RPG (http://ribosome.miyazaki-med.ac.jp/) is a new database that provides detailed information about ribosomal protein (RP) genes. It contains data from humans and other organisms, including Drosophila melanogaster, Caenorhabditis elegans, Saccharo myces cerevisiae, Methanococcus jannaschii and Escherichia coli.

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

open access: yesFEBS 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).

Detailed cytogenetic analysis of three duck species (the northern pintail, mallard, and common goldeneye) and karyotype evolution in the family Anatidae (Anseriformes, Aves)

open access: yesВавиловский журнал генетики и селекции
Galliformes and Anseriformes are two branches of the Galloanserae group, basal to other Neognathae. In contrast to Galliformes, Anseriformes have not been thoroughly researched by cytogenetic methods.

Selection and Validation of Reference Genes for Quantitative Real-Time PCR Normalization in Athetis dissimilis (Lepidoptera: Noctuidae) Under Different Conditions

open access: yesFrontiers in Physiology, 2022
Reference genes are the key to study gene expression patterns using quantitative real-time PCR (qRT-PCR). No studies on the reference genes of Athetis dissimilis, an important agricultural pest, have been reported.

Genomic function during the lampbrush chromosome stage of amphibian oogenesis [PDF]

open access: yes, 1966
Throughout its lengthy developmental history the disposition of the genetic material in the amphibian oocyte nucleus differs from that in other cell types.

Ribosomal RNA Genes in Kluyveromyces marxianus [PDF]

open access: yesMicrobiology, 1980
DNA from the yeast Kluyveromyces marxianus was studied for its heterogeneity and the multiplicity of rRNA cistrons. These cistrons banded at a slightly different density from the bulk DNA in preparative CsCl or Hg2+-Cs2SO4 equilibrium density gradients.
