Summary: Targeted immunotherapies use the binding capabilities of antibodies to enhance immune responses for long-term tumor destruction. A chemoenzymatic reaction has been developed to specifically modify a single tyrosine residue in therapeutic antibodies, allowing the attachment of fluorescent molecules or bioorthogonal groups. This reaction can be used to construct monofunctionalized antibody-drug conjugates and antibody/nanobody-conjugated effector cells, improving targeted cancer immunotherapy outcomes.

Summary: Commercially approved conventional ADCs have decreased efficacy due to heterogeneous mixtures of payloads, while AJICAP (R) technology offers a promising solution for linking hydrophobic payloads to antibodies. The controlled DAR and conjugation site in next-generation ADCs can enhance clinical efficacy and reduce toxicity, as demonstrated by site-specific ADCs produced by AJICAP (R) technology. Moreover, the FcγIIIa-NPR column can be used to characterize site-specific conjugated ADCs compared to conventional methods.

Summary: Traditional antibody-drug conjugates are limited by the large molecular weight of the antibody molecules, resulting in low permeability into solid tumors. A new cleavable ADC design with improved tumor tissue permeability and a long circulation half-life was proposed by fusing the small ADC with the Fc domain of the antibody for extended circulation and inserting a digestion sequence between them. The experimental results showed significantly enhanced tumor treatment ability of the designed molecule compared to conventional ADCs.

Summary: The study revealed that S100A11 was significantly up-regulated in NAFLD, and its overexpression could induce hepatic lipid accumulation by activating autophagy and lipogenesis processes. S100A11 may interact with HDAC6 to block its binding to FOXO1, resulting in the activation of autophagy and lipogenesis, thereby promoting lipid accumulation and liver steatosis. These findings suggest a novel S100A11-HDAC6-FOXO1 axis in regulating autophagy and liver steatosis, providing potential therapeutic targets for NAFLD.

Summary: This study investigated the molecular and cellular mechanisms of diet-induced thermogenesis (DIT) in response to high fat diet (HFD) by proteome and phosphoproteome analysis. The findings indicated that Uncoupling protein 1 (UCP1) and its phosphorylation were increased in brown adipose tissue (BAT) after HFD, along with upregulated proteins related to fatty acid oxidation and mitochondrial functions. In contrast, most metabolic-related proteins were downregulated in subcutaneous white adipose tissue (sWAT), accompanied by decreased mitochondrial proteins and inactivated kinases. These findings provide valuable insights into the differential regulatory networks of HFD in BAT and sWAT.

Summary: The study aimed to demonstrate the effectiveness of BDMC on TNF-alpha/IFN gamma-stimulated HaCaT cells and DNCB-induced AD mice. Results showed that BDMC significantly inhibited the mRNA expression of chemokines and cytokines in stimulated HaCaT cells and alleviated their inflammatory response. In vivo studies found that BDMC significantly improved AD skin lesions, decreased symptoms, improved inflammatory cell infiltration, and inhibited signaling pathways. Further clinical studies are warranted for the treatment of AD.

Summary: This study provides a detailed description of the heterogeneity of normal adjacent tissues (NATs) of hepatocellular carcinoma (HCC) and reveals their differences with healthy liver tissues. Proteomic data classifies HCC NATs into two subtypes (Subtypes 1 and 2), with Subtype 2 associated with poor prognosis and high-risk recurrence. The study also investigates the proteomic differences between NAT subtypes and healthy liver tissues, shedding light on early molecular alterations associated with the progression from healthy livers to NATs.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
