Epigenetic Regulation of Liver Fibrosis: Mechanisms and Therapeutic Implications

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
This review synthesizes the epigenetic mechanisms—DNA methylation, histone modifications, and non‐coding RNAs—that drive hepatic stellate cell activation and the progression of liver fibrosis. It further evaluates emerging therapeutic strategies targeting these epigenetic regulators, including DNA methyltransferase and histone deacetylase inhibitors ...

Evaluating Thiram‐Induced Embryotoxicity Using Integrated In Silico, In Vitro, and Transcriptomic Approaches

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Long‐term exposure to low‐dose food contact materials (FCMs) has raised concerns regarding developmental toxicity. In the present study, we prioritized FCMs with potential developmental toxicity using a weight‐of‐evidence computational model, which predicted 127 chemicals to be of high concern.

Short germ insects utilize both the ancestral and derived mode of Polycomb group-mediated epigenetic silencing of Hox genes

open access: yesBiology Open, 2015
In insect species that undergo long germ segmentation, such as Drosophila, all segments are specified simultaneously at the early blastoderm stage. As embryogenesis progresses, the expression boundaries of Hox genes are established by repression of gap ...

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

open access: yesIntegrative Zoology, EarlyView.
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.

More of the Same Makes a Difference: Comparative Anatomy and Molecular Makeup of Tenrec and Hedgehog Intestines

open access: yesIntegrative Zoology, EarlyView.
Tenrecs and hedgehogs have gastrointestinal tracts of comparable morphology, yet with marked differences in length. Among mammals, intestinal length is correlated with diet; however, these species share a common trophic niche. The length differences are accounted for by an expansion of the small intestine in the European hedgehog.

Brain metastasis‐associated fibroblasts shape the tumour microenvironment to enhance cancer cell invasion

open access: yesBrain Pathology, EarlyView.
Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.

Hox Targets and Cellular Functions

open access: yesScientifica, 2013
Hox genes are a group of genes that specify structures along the anteroposterior axis in bilaterians. Although in many cases they do so by modifying a homologous structure with a different (or no) Hox input, there are also examples of Hox genes ...

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

open access: yesThe FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

Broken colinearity of the amphioxus Hox cluster

open access: yesEvoDevo, 2012
Background In most eumetazoans studied so far, Hox genes determine the identity of structures along the main body axis. They are usually linked in genomic clusters and, in the case of the vertebrate embryo, are expressed with spatial and temporal ...

A comprehensive study on ferredoxin isoforms in the cyanobacterium Synechocystis sp. PCC 6803

open access: yesThe FEBS Journal, EarlyView.
Ferredoxins are small FeS cluster‐containing proteins that play a central role in distributing electrons within the cell. The cyanobacterium Synechocystis sp. PCC 6803 contains several ferredoxin isoforms and their biophysical properties (UV/Vis and EPR spectra, Em potential), expression patterns, and interactions with the electron donors photosystem I
