Background: Metabolic diseases pose considerable burden on the healthcare system worldwide, indi-cating the significance of prevention and treatment. In constitution theory of traditional Chinese med-icine, phlegm-dampness constitution (PDC) is the common basis of metabolic diseases. In clinical practice, Huatan Qushi (HTQS) decoction targeting on PDC can effectively improve metabolic indicators. However, its underlying biochemical mechanism still remains unclear.Methods: Eight PDC participants received HTQS decoction for three months. Their blood was collected at baseline and 1 and 3 months after intervention started. Related biomedical indicators were detected. High-throughput sequencing and RT-qPCR were used for validation. Due to the missing data, repeated measures with missing values in mixed models were used. Results: After 3-month treatment, HDL-C level increased (P<.001) and FBG, FINS, and HbA1c all showed decreasing trend at different time points (all P < .05). After miRNA high-throughput sequencing, compared with the baseline, differential miRNAs at 1 and 3 months were screened, and target gene prediction and KEGG pathway enrichment analysis were performed. The results displayed that metabolic disease-related pathways mainly included pathways in cancer, PI3K-Akt signaling pathway, etc. Further, RT-qPCR showed that hsa-miR-1237-3p differed statistically (P =.008). Then we validated the target genes of hsa-miR-1237-3p in the"Pathways in Cancer"pathway including SDF1, AC, CRK, and HGF, also known as upstream target genes of PI3K/AKT pathway. The results showed that two indicators of CRK and HGF were in statistical significance (P=.045 and P=.036, respectively). Conclusion: PDC serves as a common basis for various metabolic diseases. Through adjusting PDC, HTQS decoction can improve biomedical indicators including blood glucose, HbA1c, insulin, and HDL-C. The target pathway is"Pathways in cancer". Specifically, HTQS decoction acts on targets of CRK and HGF by regulating hsa-miR-1237-3p, and probably exerts effects on their downstream PI3K/AKT pathway.

ObjectiveTo observe the effects of Guben Fangxiao decoction-containing serum on the expression of transcription factors and cytokines associated with calcitonin gene-related peptide (CGRP), γ-aminobutyric acid (GABA), and type Ⅱ innate lymphoid cells (ILC2) in human bronchial epithelial cells (BEAS-2B) stimulated with interleukin-4 (IL-4) combined with interleukin-13 (IL-13), and explore the possible mechanism of Guben Fangxiao decoction-containing serum in alleviating type Ⅱ inflammation of bronchial epithelial cells. MethodsBEAS-2B cells stimulated with IL-4 combined with IL-13 were treated with the sera containing high (20%), medium (15%), and low (10%) doses of Guben Fangxiao decoction and the montelukast-containing serum (10%). Real-time PCR was used to measure the mRNA levels of CGRP, GABA, mucin 5AC (MUC5AC), thymic stromal lymphopoietin (TSLP), interleukin (IL)-25, IL-33, IL-5, GATA-binding protein 3 (GATA3), and B cell lymphoma/leukemia 11B (Bcl-11B) in each group. Western blot was employed to determine the relative protein levels of CGRP and MUC5AC. The immunofluorescence assay was employed to observe the relative expression of CGRP and GABA in the cells. Enzyme-linked immunosorbent assay was used to quantify the protein levels of IL-33, MUC5AC, and IL-5 in the culture and cell supernatants. Periodic acid-Schiff staining was performed to assess mucin secretion. ResultsCompared with the control group, the model group showed up-regulated mRNA levels of CGRP, GABA, MUC5AC, TSLP, IL-25, and IL-33 (P<0.05, P<0.01). Compared with the normal group, the Guben Fangxiao decoction-containing serum down-regulated the mRNA levels of CGRP, GABA, MUC5AC, IL-5, GATA3, and Bcl-11B (P<0.05, P<0.01) in a dose-dependent manner. Compared with the normal group, the model group showed up-regulated protein levels of CGRP, GABA, MUC5AC, IL-33, and IL-5 (P<0.05, P<0.01), which were down-regulated by the Guben Fangxiao decoction-containing serum (P<0.05, P<0.01). Compared with the normal group, the model group showed enhanced average fluorescence intensity of CGRP and GABA (P<0.01), which was weakened by the Guben Fangxiao decoction-containing serum (P<0.01). Compared with the normal group, the model group showed increased secretion of mucin, which was reduced by the Guben Fangxiao decoction-containing serum. ConclusionGuben Fangxiao decoction can treat bronchial asthma by alleviating type Ⅱ immune airway inflammation and reducing airway mucus secretion, which is achieved by regulating the expression of CGRP, GABA, MUC5AC, and ILC2-related transcription factors.

Cullin-RING ligases (CRLs) recognize and interact with substrates for ubiquitination and degradation, and can be targeted for disease treatment when the abnormal expression of substrates involves pathologic processes. Phosphorylation, either of substrates or receptors of CRLs, can alter their interaction. Phosphorylation-dependent ubiquitination and proteasome degradation influence various cellular processes and can contribute to the occurrence of various diseases, most often tumorigenesis. These processes have the potential to be used for tumor intervention through the regulation of the activities of related kinases, along with the regulation of the stability of specific oncoproteins and tumor suppressors. This review describes the mechanisms and biological functions of crosstalk between phosphorylation and ubiquitination, and most importantly its influence on tumorigenesis, to provide new directions and strategies for tumor therapy.
