Tetrahydroberberrubine improves hyperlipidemia by activating the AMPK/SREBP2/PCSK9/LDL receptor signaling pathway.

Hyperlipidemia is a major risk factor for hypertension, coronary heart disease, diabetes and stroke, triggering an intensified research efforts into its prevention and treatment. Tetrahydroberberrubine (THBru) is a derivative of berberine (BBR) that has been shown to have higher bioavailability and lower toxicity compared to its parent compound. However, its impact on hyperlipidemia has not been fully explored.

L3MBTL3 and STAT3 collaboratively upregulate SNAIL expression to promote metastasis in female breast cancer.

The STAT3 pathway promotes epithelial-mesenchymal transition, migration, invasion and metastasis in cancer. STAT3 upregulates the transcription of the key epithelial-mesenchymal transition transcription factor SNAIL in a DNA binding-independent manner. However, the mechanism by which STAT3 is recruited to the SNAIL promoter to upregulate its expression is still elusive.

Aggregation-Induced Emission Luminogens Realizing High-Contrast Bioimaging.

A revolutionary transformation in biomedical imaging is unfolding with the advent of aggregation-induced emission luminogens (AIEgens). These cutting-edge molecules not only overcome the limitations of traditional fluorescent probes but also improve the boundaries of high-contrast imaging. Unlike conventional fluorophores suffering from aggregation-caused quenching, AIEgens exhibit enhanced luminescence when aggregated, enabling superior imaging performance.

Comprehensive analysis of heterogeneity and cell-cell interactions in Crohn's disease reveals novel location-specific insights.

Introduction: In Crohn's disease (CD), lesions are mainly distributed in a segmental manner, with the primary sites of involvement being the ileum and colon. Heterogeneity in colon and ileum results in location-specific clinical presentations and therapeutic responses. Mucosal healing tends to be more readily and quickly achieved in the colon than in the ileum, where lesions are more likely to develop into complex behaviors.

PFKFB3-dependent redox homeostasis and DNA repair support cell survival under EGFR-TKIs in non-small cell lung carcinoma.

Background: The efficacy of tyrosine kinase inhibitors (TKIs) targeting the EGFR is limited due to the persistence of drug-tolerant cell populations, leading to therapy resistance.

Trpv1-lineage neuron-expressing Kcnq4 channel modulates itch sensation in mice.

Voltage-gated potassium channel subfamily q member 4 (Kcnq4) is predominantly expressed by hair cells and auditory neurons and regulates the neuronal excitability in the auditory pathway. Although it is further detected in myelinated large-diameter dorsal root ganglia (DRG) neurons in the periphery, the expression and function of Kcnq4 channel in nociceptors remains unknown. Here we showed that Kcnq4 is substantially expressed by unmyelinated small-diameter DRG neurons in both human and mouse.
