Current Applications of Colorectal Cancer Organoids: A Review.

Colorectal cancer is a prevalent malignancy, with advanced and metastatic forms exhibiting poor treatment outcomes and high relapse rates. To enhance patient outcomes, a comprehensive understanding of the pathophysiological processes and the development of targeted therapies are imperative. The high heterogeneity of colorectal cancer demands precise and personalized treatment strategies.

Numerical simulation analysis of heat and mass transfer of saline wastewater in a falling film evaporation tube based on different inlet modes.

Falling film evaporation technology is widely used in the treatment of salt-containing wastewater in coal chemical industry. However, there is still a lack of research on the inlet method of vertical falling film evaporation tubes. In this paper, the heat and mass transfer processes of saline wastewater under vertical and tangential inlets were investigated using numerical simulations.

[Effect of Huangqin Decoction on pyroptosis pathway of NLRP3/caspase-1 in mice with ulcerative colitis].

To explore the effect of Huangqin Decoction on ulcerative colitis(UC) pyroptosis, and to explain the mechanism of pyroptosis based on NOD-like receptor thermoprotein domain 3(NLRP3)/cysteine proteinase 1(caspase-1) pathway. The animal model of UC induced with 3% dextran sodium sulfate(DSS) was established. The experimental animals were divided into control group, model group, low-dose(4.

[Bioinformatics analysis and systematic review of key genes and therapeutic traditional Chinese medicine of ulcerative colitis active stage].

Data GSE75214 and GSE48959 that contained ulcerative colitis(UC) in the active stage was download from GEO database. Differential genes of UC in the active phase were obtained by using adjusted P<0.05 and |log_2 FC|≥1.

Quantification of Proliferative and Dead Cells in Enteroids.

The intestinal epithelium acts as a barrier that prevents luminal contents, such as pathogenic microbiota and toxins, from entering the rest of the body. Epithelial barrier function requires the integrity of intestinal epithelial cells. While epithelial cell proliferation maintains a continuous layer of cells that forms a barrier, epithelial damage leads to barrier dysfunction.

Intracellular MLCK1 diversion reverses barrier loss to restore mucosal homeostasis.

Epithelial barrier loss is a driver of intestinal and systemic diseases. Myosin light chain kinase (MLCK) is a key effector of barrier dysfunction and a potential therapeutic target, but enzymatic inhibition has unacceptable toxicity. Here, we show that a unique domain within the MLCK splice variant MLCK1 directs perijunctional actomyosin ring (PAMR) recruitment.

Interleukin 22 Expands Transit-Amplifying Cells While Depleting Lgr5 Stem Cells via Inhibition of Wnt and Notch Signaling.

Background & Aims: Epithelial regeneration is essential for homeostasis and repair of the mucosal barrier. In the context of infectious and immune-mediated intestinal disease, interleukin (IL) 22 is thought to augment these processes. We sought to define the mechanisms by which IL22 promotes mucosal healing.

In Vitro and In Vivo Approaches to Determine Intestinal Epithelial Cell Permeability.

The intestinal barrier defends against pathogenic microorganism and microbial toxin. Its function is regulated by tight junction permeability and epithelial cell integrity, and disruption of the intestinal barrier function contributes to progression of gastrointestinal and systemic disease. Two simple methods are described here to measure the permeability of intestinal epithelium.

Myosin regulatory light chain phosphorylation is associated with leiomyosarcoma development.

Leiomyosarcoma is a rare malignant smooth muscle tumor which can be very unpredictable. Myosin II is involved in many functions, including cell contraction, migration, and adhesion. The phosphorylation of myosin regulatory light chain (MLC) by myosin light chain kinase (MLCK) determines the activity of Myosin II.

The molecular mechanism of CRISPR/Cas9 system and its application in gene therapy of human diseases.

CRISPR/Cas system is an adaptive immune system that confers resistance to exogenous virus or plasmid in bacteria and archaea. In recent years, the booming CRISPR/Cas9 genome editing technology modified from type2 CRISPR/Cas adaptive immune system has been widely applied to various research fields of life science and led to revolutionary changes. In this review, we summarize the origin and development of CRISPR/Cas9 genome editing technology as well as its applications in life science research.
