MetabolomicsMethionine Intervention Induces PD-L1 Expression to Enhance the Immune Checkpoint Therapy Response in MTAP-deleted Osteosarcoma
Osteosarcoma (OS), a malignant bone tumor with limited treatment options, exhibits low sensitivity to immune checkpoint therapy (ICT). Through genomics and transcriptomics analyses, we have identified a subgroup of OS with methylthioadenosine phosphorylase (MTAP) deletion, which contributes to ICT r...

ProteomicsNoncanonical amino acid-aided synthesis of anti-PD-L1 bispecific nanobody for colon cancer immunotherapy
Colorectal cancer (CRC) is the second leading cause of cancer-related mortality, and the incidence of early-onset colon cancer has been increasing globally in recent years. The development of immunotherapies for colon cancer is critical for providing new treatment strategies to combat drug resistanc...

ProteomicsIntegrating Protein Language Models and Automatic Biofoundry for Enhanced Protein Evolution
Traditional protein engineering methods, such as directed evolution, while effective, are often slow and labor-intensive. Advances in machine learning and automated biofoundry present new opportunities for optimizing these processes. This study devises a protein language model-enabled automatic evol...

ProteomicsMachine learning-guided evolution of pyrrolysyl-tRNA synthetase for improved incorporation efficiency of diverse noncanonical amino acids
The pyrrolysyl-tRNA synthetase (PylRS) is widely used to incorporate noncanonical amino acids (ncAAs) into proteins. However, most of ncAA-containing protein yields remain low due to the limited activity of PylRS variants. Here, we apply machine learning (ML) to engineer the tRNA-binding domain of P...

MetabolomicsGut microbiota production of trimethyl-5-aminovaleric acid reduces fatty acid oxidation and accelerates cardiac hypertrophy
Numerous studies found intestinal microbiota alterations which are thought to affect the development of various diseases through the production of gut-derived metabolites. However, the specific metabolites and their pathophysiological contribution to cardiac hypertrophy or heart failure progression ...

MetabolomicsAdaptation of gut microbiome and host metabolic systems to lignocellulosic degradation in bamboo rats

Bamboo rats (Rhizomys pruinosus) are among the few mammals that lives on a bamboo-based diet which is mainly composed of lignocellulose. However, the mechanisms of adaptation of their gut microbiome and metabolic systems in the degradation of lignocellulose are largely unknown. Here, we ...

ProteomicsProteomic analysis of periodontal tissue reveals β-guanidinopropionic acid (β-GPA) mediated inhibition of the TLR4 pathway in a mouse model of hyperlipidemic periodontitis.
This project aims to elucidate the molecular mechanisms by which the gut microbial metabolite β-guanidinopropionic acid (β-GPA) alleviates hyperlipidemic periodontitis (HPD). We performed Tandem Mass Tag (TMT) based quantitative proteomic analysis on periodontal tissues from HPD model mice versus th...

ProteomicsMouse Neuroblastoma Cells Proteome by LC-MS/MS
N2a cells were transfected with pCAGGS vector or pCAGGS-RABV-M (expressing rabies virus matrix protein) for 36 hours, cells were lysed for SDS-PAGE. The area where the proteins were located in the SDS-PAGE was scooped and cut into small pieces of about 1 mm3; the decolorization solution (15 mM K3Fe(...

ProteomicsQuantitative Pattern of hPTMs by Mass Spectrometry-based Proteomics with Implications for Triple-Negative Breast Cancer
Triple-negative breast cancer (TNBC) is characterized by its aggressive behavior, with trend to early relapse and metastasis as well as poor survival. Limited therapies and lack of effective therapeutic targets are one of the main challenges in clinical management of TNBC. Histone post-translationa...
