Vsx2 controls eye organogenesis and retinal progenitor identity via homeodomain and non-homeodomain residues required for high affinity DNA binding. [PDF]
The homeodomain and adjacent CVC domain in the visual system homeobox (VSX) proteins are conserved from nematodes to humans. Humans with missense mutations in these regions of VSX2 have microphthalmia, suggesting both regions are critical for function ...

Small‐Molecule Kinase Inhibitors Modulating Circadian Rhythms
ABSTRACT The circadian clock mechanism generates 24‐h rhythms crucial for regulating various physiological processes, and its dysregulation has been implicated in numerous diseases. In cells, the circadian clock operates through a transcriptional‐translational feedback loop, where phosphorylation plays a pivotal role in maintaining accurate circadian ...

Gene turnover in the common ancestor of all C4 grasses
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Papillary Thyroid Cancer With Cutaneous Metastasis: A Case Report and Literature Review
ABSTRACT Background Cutaneous metastasis of papillary thyroid carcinoma is rare, which may present as slowly growing nodules, erythematous papules, or ulcerative nodules. The pathophysiological mechanisms of skin metastasis in thyroid cancer remain unclear.

Adaptive evolution of Hox-gene homeodomains after cluster duplications
Background Hox genes code for homeodomain-containing transcription factors that function in cell fate determination and embryonic development. Hox genes are arranged in clusters with up to 14 genes.

The sequence specificity of homeodomain-DNA interaction [PDF]
The Drosophila developmental gene, engrailed, encodes a sequence-specific DNA binding activity. Using deletion constructs expressed as fusion proteins in E. coli, we localized this activity to the conserved homeodomain (HD). The binding site consensus, TCAATTAAAT, is found in clusters in the engrailed regulatory region. Weak binding of the En HD to one

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...

The vertebrate retina is made up of six specialized neuronal cell types and one glia that are generated from a common retinal progenitor. The development of these distinct cell types is programmed by transcription factors that regulate the expression of ...

The tomato mars1/rough mutant displays enhanced root regeneration and rough fruits due to ectopic cell proliferation. The causal gene encodes a lysine‐specific histone demethylase that normally maintains gene silencing. Its loss alters histone methylation, upregulating several genes, including those B‐type cyclins involved in tissue‐specific cellular ...
