Objective:To investigate the optimal processing technology for Sophorae Fructus Carbonisata(char-coal-processed immature fruit of Sophora japonica)by integrating thermal analysis,response surface methodology(RSM),and intelligent sensory technology.Methods:The thermal analysis technology was used to simulate the processing process of traditional Chinese medicine(TCM),the pyrolysis characteristics of Sophorae Fructus powder were studied,and the processing process was discussed by intelligent sensory analysis to determine the temperature range.Using the contents of genistein,kaempferol,and quercetin as comprehensive evaluation indices,the RSM was applied to optimize the processing technology for Sophorae Fructus Carbonisata.Results:The optimal process-ing technology for Sophorae Fructus Carbonisata was identified as:Stir-frying temperature was 290 ℃,Stir-frying time was 14 min.Conclusion:The integrated approach of thermal analysis-RSM and intelligent sensory technology has successfully established an accurate predictive model for active components in Sophorae Fructus.The optimized processing technology not only enhances the reproducibility of charcoal processing but also lays a foundation for the formulation of national quality standards for this TCM.

Tripartite motif (TRIM) family proteins are important effectors of innate immunity against viral infections. Here we identified TRIM35 as a regulator of TRAF3 activation. Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon (IFN) in response to viral infection. Trim35-deficient mice were more susceptible to influenza A virus (IAV) infection than were wild-type mice. TRIM35 promoted the RIG-I-mediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1. IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3. TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2, thereby antagonizing its suppression of TRAF3 activation. Our in vitro and in vivo findings thus reveal novel roles of TRIM35, through catalyzing Lys63- or Lys48-linked polyubiquitination, in RIG-I antiviral immunity and mechanism of defense against IAV infection.

PURPOSE: Breast cancer (BC) is one of the most common malignancies globally, and millions of women worldwide are diagnosed with BC every year. Up to 70% of BC patients are estrogen receptor (ER)-positive. Numerous studies have shown that tamoxifen has a significant therapeutic effect on both primary and metastatic ER-positive BC patients. Although tamoxifen is currently one of the most successful therapeutic agents for BC, a significant proportion of patients will eventually become resistant to tamoxifen, leading to tumor recurrence and metastasis. Knowledge about the development of tamoxifen resistance in BC patients is still limited. METHODS: We applied a loss-and-gain method to study the biological functional role of cell division cycle associated 8 (CDCA8) in tamoxifen resistance in BC cells. RESULTS: We found that CDCA8 was significantly elevated in tamoxifen-resistant BC cells. Knockdown of CDCA8 expression significantly inhibited the proliferation of tamoxifen-resistant BC cells and reduced their resistance to tamoxifen. In contrast, overexpression of CDCA8 promoted the growth of tamoxifen-sensitive BC cells and induced their resistance to tamoxifen. CONCLUSION: In this study, we reported that CDCA8 is a key regulator of tamoxifen resistance in BC, suggesting that CDCA8 may serve as a potential therapeutic target for BC treatment.
