Colorectal cancer (CRC) has been the third most common malignancy and the second cause of cancer-related mortality. As the core of volume-sensitive chloride currents, leucine-rich repeat-containing 8A (LRRC8A) contributes to tumor progression but is not consistent, especially for whom the roles in colon carcinoma metastasis were not fully elucidated. Herein, LRRC8A proteins were found highly expressed in hematogenous metastasis from human colorectal cancer samples. The oxaliplatin-resistant HCT116 cells highly expressed LRRC8A, which was related to impaired proliferation and enhanced migration. The over-expressed LRRC8A slowed proliferation and increased migration ex vivo and in vivo. The elevated LRRC8A upregulated the focal adhesion, MAPK, AMPK, and chemokine signaling pathways via phosphorylation and dephosphorylation. Inhibition of LRRC8A impeded the TNF-α signaling cascade and TNF-α-induced migration. LRRC8A binding to PIP5K1B regulated the PIP2 formation, providing a platform for LRRC8A to mediate cell signaling transduction. Importantly, LRRC8A self-regulated its transcription via NF-κB1 and NF-κB2 pathways and the upregulation of NIK/NF-κB2/LRRC8A transcriptional axis was unfavorable for colon cancer patients. Collectively, our findings reveal that LRRC8A is a central mediator in mediating multiple signaling pathways to promote metastasis and targeting LRRC8A proteins could become a potential clinical biomarker-driven treatment strategy for colon cancer patients.

Gentamicin causes kidney injury due to its accumulation in proximal tubule epithelial cells via the megalin/cubilin/CLC-5 complex. Recently, shikonin has been shown to have potential anti-inflammatory, antioxidant, antimicrobial, and chloride channel-inhibiting effects. The current study investigated the alleviation of gentamicin-induced renal injury by shikonin while preserving its bactericidal effect. Nine-week-old Wistar rats were administered 6.25, 12.5, and 25 mg/kg/day shikonin orally, one hour after the i.p. injection of 100 mg/kg/day gentamicin for seven days. Shikonin significantly and dose-dependently alleviated gentamicin-induced renal injury, as revealed by restoring normal kidney function and histological architecture. Furthermore, shikonin restored renal endocytic function, as indicated by suppressing the elevated renal megalin, cubilin, and CLC-5 and enhancing the reduced NHE3 levels and mRNA expressions induced by gentamicin. These potentials could be attributed to the modulation of the renal SIRT1/Nrf2/HO-1, TLR-4/NF-κB/MAPK, and PI3K/Akt cascades, which enhanced the renal antioxidant system and suppressed renal inflammation and apoptosis, as indicated by enhancements of SIRT1, Nrf2, HO-1, GSH, SOD, TAC, Iκb-α, Bcl-2, PI3K, and Akt levels and mRNA expressions, with reduction of TLR-4, NF-κB, MAPK, IL-1β, TNF-α, MDA, iNOS, NO, cytochrome c, caspase-3, Bax levels, and Bax/Bcl-2 ratio. Therefore, shikonin is a promising therapeutic agent for alleviating gentamicin-induced renal injury.

OBJECTIVETo observe the effects of Xiaoqinglong Decoction and Qingqi Huatan Pills on interleukin-1β (IL-1β)-induced mucushypersecretion model of human airway epithelial H292 cellsand related molecules of nuclear factor-κB/microRNA-494(NF-κB/miR-494) signaling pathway, and to explore the mechanism of the two medicines in improving pathological airway mucus.METHODSMethyl thiazolyl tetrazolium (MTT) colorimetric method was used to detect the effects of different concentrations of Xiaoqinglong Decoction and Qingqi Huatan Pills on the activity of H292 cellsinduced by IL-1β, and the appropriate concentration was selected for subsequent experiments. Cells were randomly divided into blank group, IL-1β model group (5 μg/L IL-1β), NF-κB inhibitor pyrrolidinedithiocarbamate (PDTC) group (5 μg/L IL-1β+100 μmol/L PDTC), Xiaoqinglong Decoction (5 μg/L IL-1β+1 000 mg/L Xiaoqinglong Decoction) and Qingqi Huatan Pill group (5 μg/L IL-1β+1 000 mg/L Qingqi Huatan Pills). 5 μg/L IL-1β was used to induce H292 cells for 24 hours to establish a model of airway epithelial mucus hypersecretion. Enzyme linked immunosorbent assay (ELISA) method was used to detect the levels of mucin 5AC (MUC5AC), tumor necrosis factor-α (TNF-α) and IL-8 and the synthesis of intracellular MUC5AC and cystic fibrosis transmembrane conductance regulator (CFTR). Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression levels of MUC5AC mRNA, CFTR mRNA, miR-494. Western blotting was used to detect protein expression of key proteins (p65) and NF-κB inhibitors (IκB) in NF-κB signaling pathway.RESULTSXiaoqinglong Decoction and Qingqi Huatan Pills with the concentration of 1 000 mg/L were selected for the follow-up experiment. Compared with the blank group, the levels of MUC5AC, TNF-α and IL-8 were significantly increased in the model group, intracellular MUC5AC protein content and mRNA expression were also significantly increased, intracellular CFTR protein content and mRNA expression were significantly decreased, and intracellular p65 protein expression was significantly up-regulated, the expression of IκB protein was significantly down-regulated, and the expression of miR-494 was significantly increased. Compared with the model group, the levels of MUC5AC, TNF-α and IL-8 were significantly reduced in PDTC group, Xiaoqinglong Decoction group and Qingqi Huatan Pill group, intracellular MUC5AC protein content and mRNA expression were also significantly decreased, and intracellular p65 protein expression was significantly down-regulated, and IκB protein expression was significantly up-regulated, miR-494 expression was significantly reduced. Intracellular CFTR protein content and mRNA expression were significantly increased in both PDTC group and Qingqi Huatan Pill group. Compared with the PDTC group, the level of TNF-α in the Xiaoqinglong Decoction group was significantly increased (ng/L: 22.77±3.14 vs. 11.09±3.37, P < 0.05),the content and mRNA expression of CFTR and IκB protein expression was significantly decreased [CFTR protein (ng/L): 97.38±6.62 vs. 227.04±19.48, CFTR mRNA (2^-ΔΔCt): 0.99±0.08 vs. 1.21±0.08, IκB/β-actin: 1.69±0.11 vs. 2.00±0.18, all P < 0.05], the level of TNF-α in Qingqi Huatan Pill group was significantly higher (ng/L: 19.08±3.71 vs. 11.09±3.37, P < 0.05). Compared with Xiaoqinglong Decoction group, the protein content and mRNA expression of CFTR and IκB protein expression in Qingqi Huatan Pill group were significantly increased [CFTR protein (ng/L): 235.01±22.71 vs. 97.38±6.62, CFTR mRNA (2^-ΔΔCt): 1.32±0.15 vs. 0.99±0.08, IκB/β-actin: 1.94±0.16 vs. 1.69±0.11, all P < 0.05].CONCLUSIONSThe effect of Xiaoqinglong Decoctionin improving the hypersecretion of mucus in the airway epithelium may be related to the inhibition of NF-κB/miR-494 inflammatory signal-mediated MUC5AC hypersecretion, while the effect of Qingqi Huatan Pills may be related to the inhibition of NF-κB/miR-494 inflammatory signal-mediated MUC5AC hypersecretion and CFTR dysfunction. Therefore, the difference in the mechanism of the two treatments of airway pathological mucus is mainly in the regulation of CFTR mRNA and protein.
