Epigenetic regulation, which is reversible, plays a significant role in cancer progression. CBX3 (HP1γ), a key heterochromatin protein, regulates gene expression by interacting with histone H3 lysine 9 trimethyl (H3K9me3) markers. While CBX3 is linked to tumor progression in various cancers, its role in CCA remains unclear. This study reveals that CBX3 and H3K9me3 enrich the HLTF promoter, a gene involved in chromatin remodeling and DNA repair. HLTF is often inactivated by hypermethylation in other cancers, suggesting tumor-suppressive properties. Depleting CBX3 in CCA cells elevates HLTF expression, reducing proliferation, while HLTF silencing reverses this effect. Furthermore, HLTF overexpression inhibits PI3K-AKT signaling activated by CBX3.

The accumulation of double-stranded DNA within the cytosol triggers the activation of cytosolic DNA-sensing pathways, notably the Stimulator of Interferon Genes (STING) pathway. However, the precise role of STING in driving steroid hyporesponsiveness remains elusive and warrants further investigation. This study evaluates STING levels in human bronchial fibroblasts from severe asthmatic patients and in lung homogenates from a steroid hyporesponsive lung inflammation mouse model. STING level is assessed at baseline, post house dust mites (HDM) stimulation, and following treatment with dexamethasone and STING inhibitor. The effect of STING inhibitors on regulating steroid hyporesponsiveness particularly glucocorticoid receptor (GR)-α/GR-β ratio is also examined. Severe asthmatic fibroblasts exhibit elevated STING/IFN-I pathway activation, further heightened by HDM and a similar pattern is seen in lung homogenates from steroid hyporesponsive mice. Dexamethasone combined with an STING inhibitor reduces STING activity, while dexamethasone alone is ineffective. Interestingly, the STING inhibitor restores steroid sensitivity by increasing the GRα/GRβ ratio. Furthermore, nanoparticle-encapsulated STING inhibitor more effectively reduces airway hyperresponsiveness and restores steroid sensitivity than the free inhibitor.

The blood-borne ingredients of TJM are identified by the Ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometer. Subsequently, a \"compound-target-disease\" network is established and obtained core targets associated with TJM and RE.

Finally, the rat model of RE is established to verify the results predicted by network pharmacology through animal experiments. Fifteen blood-borne ingredients of TJM are identified, with eight active ingredients-namely Tangeretin, Tricin, Palmati, Berberine, Limonin, Evodiamine, Tetrahydropalmatine and Rutecarpine - making significant contributions to its efficacy. Moreover, TJM is predicted to act on 193 targets related to RE, involving AKT1, HSP90AA1, PIK3CA, and other targets, which enriches mainly in PI3K/AKT /NF-κB signaling. Additionally, TJM can alleviate inflammation of the esophageal mucosa, reduce pathological damage, and increase gastric pH.
