Article Abstract
The small intestinal epithelium develops from embryonic endoderm into a highly specialized layer of cells perfectly suited for the digestion and absorption of nutrients. The development, differentiation, and regeneration of the small intestinal epithelium require complex gene regulatory networks involving multiple context-specific transcription factors. The evolutionarily conserved GATA family of transcription factors, well known for its role in hematopoiesis, is essential for the development of endoderm during embryogenesis and the renewal of the differentiated epithelium in the mature gut. We review the role of GATA factors in the evolution and development of endoderm and summarize our current understanding of the function of GATA factors in the mature small intestine. We offer perspective on the application of epigenetics approaches to define the mechanisms underlying context-specific GATA gene regulation during intestinal development.

To investigate the clinicopathological features, diagnosis and differential diagnosis of primary bladder lymphoma. A retrospective study was conducted on 23 cases of primary bladder lymphoma diagnosed at Beijing Friendship Hospital of Capital Medical University between February 2010 and April 2024. The clinicopathological data were collected and analyzed, and literature was reviewed.

Oleaginous filamentous fungus Mucor circinelloides harbors a GATA transcription activator AreA, which regulates nitrogen metabolism. In our previous study, deletion of AreA resulted in increased lipid production, while its overexpression reduced lipid synthesis. Although it is not a direct lipogenesis regulator, AreA influences metabolic flux by modulating nitrogen utilization pathways, which in turn affects carbon distribution.

The biocontrol fungus Purpureocillium lilacinum PLBJ-1 produces leucinostatins, a class of non-ribosomal peptides (NRPs) with broad-spectrum antimicrobial activities. However, the molecular mechanisms underlying the optimization of culture conditions for leucinostatin production remain unexplored. Previous research showed that PLBJ-1 synthesizes leucinostatins more effectively in hand-made Potato Dextrose Broth (PDB-M) than in commercially available PDB (PDB-C).

Cardiogenesis relies on the integrated interplay between cardiac transcription factors and signaling pathways. Here, we uncover a role for type IIA procollagen (IIA), an extracellular matrix (ECM) protein encoded by an alternatively spliced transcript, encoding a N-terminal cysteine-rich domain, as a critical regulator in a cardiac gene regulatory feedback loop. The cysteine-rich domain of IIA protein was previously reported to interact with bone morphogenetic proteins (BMPs) and transforming growth factors-beta (TGFβ) in in vitro binding assays and acts as a BMP antagonist in amphibian embryo assays.

Tropomyosin is a significant allergen found in invertebrates and is recognized as one of the primary triggers of food-induced anaphylaxis. Though many researchers have done the characterization of allergic tropomyosin, a comparative analysis of the allergenicity of vertebrate (porcine) and invertebrate (crab) tropomyosin is still lacking. The present study aims to study the differences in IgE, tropomyosin-specific IgE, and histamine levels between vertebrate (porcine) and invertebrate tropomyosin (crab) using an animal experimental model.
