Gene Frequencies in the Domestic Cats of Adelaide [PDF]

open access: yesAustralian Journal of Biological Sciences, 1973
A survey of 600 stray cats from industrial-urban areas of Adelaide was conducted and the frequencies of some genes controlling coat colour were determined. The sample fitted a I : 1 sex ratio and comparison of observed and expected phenotypes at the orange locus established that the population was panmictic.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Determining the Frequency of Genes Producing Colicins Ia and V in Escherichia coli Strains Isolated from Clinical Samples of Medical Centers in Yazd City [PDF]

open access: yesMajallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2023
Introduction: Bacteriocins are peptides with antimicrobial properties. They are ribosomally synthesized and produced by both gram-positive and gram-negative bacteria. The bacteriocins produced by Escherichia coli are called colicins.

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

open access: yesFEBS 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 ...

Low frequency of ESRRA-C11orf20 fusion gene in ovarian carcinomas.

open access: yesPLoS Biology, 2014
The identification of recurrent gene fusions in common epithelial cancers--for example, TMPRSS2/ERG in prostate cancer and EML4/ALK in nonsmall cell lung carcinomas--has raised the question of whether fusion genes are pathogenetically important also in ...

Gene Expression: Dialing Up the Frequency [PDF]

open access: yesCurrent Biology, 2008
Cells often respond to external signals by altering their gene expression. The external signaling information is transduced and typically encoded in concentrations of relevant transcription factors. A recent study demonstrates that, by encoding this information in the frequency with which genes 'see' a transcription factor, the expression of hundreds ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

FREQUENCY OF NRAS AND KRAS GENES IN NEWLY DIAGNOSED ACUTE MYELOID LEUKEMIA PATIENTS

open access: yesPakistan Armed Forces Medical Journal, 2020
Objective: To determine the frequency of NRAS and KRAS mutations in newly diagnosed acute myeloid leukemia patients and correlation with their clinicopathological parameters along with prognostic impact. Study Design: Cross-sectional study.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
