CLDN2 (Claudin 2)

Remarkably, disrupting CLDN2 completely eliminates the metastatic advantage caused by IKKα loss. These results identify a metastasis-competent epithelial state driven by tight-junction remodeling and uncover a vulnerable node that may be exploited therapeutically in aggressive colorectal cancer.

In vitro functional assays revealed that CLDN12 knockdown suppressed LUAD cell proliferation, migration, and invasion while promoting cell apoptosis. In summary, CLDN12 may serve as a promising biomarker for LUAD detection and a potential therapeutic target.

Our comprehensive analysis establishes CLDN22 as a novel prognostic and predictive biomarker in gliomas with significant implications for patient stratification and therapeutic decision-making. These findings provide new insights into glioma biology and potential therapeutic strategies, though further experimental validation is warranted.

Our findings highlight FAM83A as a potential prognostic biomarker with significant implications for treatment strategies, especially concerning immune modulation. This study offers a more comprehensive insight into the molecular differences in LUAD in smokers and non-smokers and lays the groundwork for targeted therapies tailored to these subgroups.

These findings demonstrated that CLDN2 regulates metastatic gene expression in CRC. Although further mechanistic studies are warranted, the present study provided notable genetic and phenotypic evidence of the role of CLDN2 in promoting cancer cell migration and invasion, offering a potential foundation for future studies into its signaling interactions and therapeutic potential.

The oncogenic role of THBS1 and its therapeutic vulnerability were validated by in vitro experiments using human laryngeal cancer cell lines. Our study supports THBS1 as a potential prognostic predictor with therapeutic vulnerability for laryngeal cancer, warranting further clinical validation.

The further in vitro experiments showed that CLDN2 knockdown significantly decreased the migration and invasion of MCF-7 cells. The study points out the potential cancer-promoting risks of exposure to ZnO NPs at low dose and under long-term exposure condition, and the importance of using real-life exposure scenarios to fully assess the safety of NPs.

Further, S.b.S normalized expression of nucleotide binding oligomerization domain (Nod)2- (from 44.5 to 0.51, p < 0.0001) and matrix metalloproteinase (Mmp)7-dependent activation (from 28.3 to 0.02875 ± 0.0044 ** p < 0.01) of antimicrobial peptide defense and reduced the expression of several inflammatory markers, such as myeloid differentiation primary response 88 (Myd88) (p < 0.01), tumor necrosis factor α (Tnfα) (p < 0.01), interleukin (IL)-6 (p < 0.01), and IL-1β (p < 0.001). Our data provide new insights into the molecular mechanisms by which Saccharomyces boulardii CNCM I-745-derived secretome attenuates inflammatory responses and restores GI barrier function in small intestinal organoids.

This integrative approach highlights the com-plexity of tissue-specific gene regulation mediated by endometriosis-associated variants. Our findings provide a functional framework to prioritize candidate genes and support new mechanistic hypotheses for the molecular pathophysiology of endometriosis.

Immunophenotyping of murine spleens showed that this delay in disease was accompanied by more tumor-reactive CD8+ T cells that co-expressed fewer inhibitory receptors (e.g., PD-1, LAG3, TIM3). These findings confirm a dysbiotic gut microbiome develops during CLL disease and demonstrate unique intestinal involvement and potential immune dysregulation occurring during CLL progression that may be influencing the overall microbial signature.

The study identified that some candidate genes, including solute carrier family 4 member 3 (SLC4A3), ADAM metallopeptidase domain 12 (ADAM12), and B-cell lymphoma 2-associated-athanogene 3 (BAG3), were significantly upregulated, whereas claudin 23 (CLDN23) and glucose-6-phosphatase catalytic subunit 1 (G6PC1) were markedly downregulated in the API group in comparison with that in the DIQ group (p < 0.05). Collectively, our findings provide molecular evidence for the beneficial effects of apigenin and sodium butyrate against oxidative stress in the jejunum of ducks.

Organoid cells derived from a breast cancer patient with pulmonary metastasis at initial diagnosis, when perfused into the system, selectively invaded the lung organ, but did not invade the liver, bone, or control pores. This leaf-vein-inspired multi-organ microfluidic chip demonstrates significant application value for studying breast cancer CTC organotropism and serves as a powerful predictive tool for early warning of high-risk organ metastasis.
