However, its underlying mechanism has not been clarified. The Zhimu-Huangbo (ZMHB) herb pair, a classic formulation historically employed in traditional Chinese medicine, demonstrates neuroprotective effects, including the amelioration of cognitive dysfunction. Emerging evidence suggests that the exosomal pathway may regulate abnormalities in diabetes-induced AQP4 polarization. Nevertheless, whether the neuroprotective effects of ZMHB mediate the restoration of AQP4 polarity through the exosomal pathway remains to be elucidated. This study takes the exosomal pathway as the entry point to elucidate the mechanism of AQP4 depolarization in DCI and determine how ZMHB restores AQP4 polarization and improves cognitive function. ZMHB significantly improved cognitive function, effectively restored GS function and maintained AQP4 polarization. Pharmacological blockade of exosomal pathways partially reduced the therapeutic effects of ZMHB, demonstrating that its efficacy depends on exosome-mediated signaling; proteomics combined with western blotting validation revealed tissue inhibitor of metalloproteinase 3 (TIMP3) as a pivotal protein modulated by ZMHB, which restored AQP4 polarization by inhibiting matrix metalloproteinase-9 (MMP9) activity and blocking β-dystroglycan (β-DG) cleavage in astrocytes. In vitro studies further demonstrated that both ZMHB-treated serum exosomes (ZMHB-sExos) and the TIMP3 agonist MPT0B390 restored astrocytic AQP4 polarization by modulating the MMP9/β-DG pathway.

Preceding carbohydrate intake with dietary fiber or protein was associated with significant attenuation of postprandial glucose excursions compared with carbohydrate alone. This effect was particularly evident within the first 120 minutes after eating and was most pronounced when fiber and protein were consumed in combination. Attenuation occurred in both healthy individuals and participants with type 2 diabetes, though the magnitude of suppression varied across groups.

Moreover, the TRPC6 gene was linked to immune infiltration in breast cancer, and this relationship affected the prognosis of breast cancer. In contrast to published researches, we found that TRPC6 expression was negatively correlated with breast cancer cell proliferation and metastasis abilities, suggesting TRPC6 as a promising prognostic biomarker for breast cancer, where low expression of TRPC6 was related to worse prognoses.

The purity of G1H2GC2 was over 97% in RP-HPLC, and its high purity was further verified by the appearance of a single band on sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The protein content of G1H2GC2 was found to be over 99% by Bradford assay. The molecular weight was determined as 25.6 kDa by electrospray ionization-mass spectrometry (ESI-MS/MS). The isoelectric point of G1H2GC2 was measured to be 7.71 by isoelectric focusing-polyacrylamide gel electrophoresis (IEF-PAGE). Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS/MS) was employed to detect and identify the protein by mass fingerprinting coupled with fragmentation patterns. No matched protein was found, confirming that G1H2GC2 was a novel protein. An attempt was made to detect the N-terminal amino acid sequence of G1H2GC2 by Edman degradation, but the sequence of G1H2GC2 was found to be blocked. The scavenging percentage of G1H2GC2 at 15 mg/mL against 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS<sup>•+</sup>) was 52.84%. The median effective concentration (EC<sub>50</sub>) value of G1H2GC2 against ABTS<sup>•+</sup> was 17.67 mg/mL. The results showed that G1H2GC2 might be developed as a potential food additive agent.</p>","PeriodicalId":520606,"journal":{"name":"Drug discoveries & therapeutics","volume":" ","pages":"304-313"},"PeriodicalIF":0.0,"publicationDate":"2025-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
