ProteomicsMass spectrometry data of human urine
Based on UPLC-Q-TOF-MS metabolomics technology, urine samples of 1072 subjects from 9 centers, including normal control, phlegm and blood stasis (PBS) syndrome and Qi and Yin deficiency (QYD) syndrome, and other syndromes of CHD, were conducted to find biomarkers. Among them, the discovery set (n = ...

ProteomicsIdentification of Unknown Biological Toxin Protein Using Mass Spectrometry: A Case Study on De Novo Sequencing of Ricin
Currently, the genomes of many toxin proteins remain unsequenced. Characterizing these toxin proteins and their active peptide segments is crucial for the development of detoxification agents and for discovering proteins with potential therapeutic applications. Existing methods for identifying and d...

MetabolomicsSerum metabolomic profiles for distinguishing lung cancer from pulmonary tuberculosis: identification of rapid and noninvasive biomarker

BACKGROUND: Pulmonary tuberculosis (TB) and lung cancer (LC) have similar clinical symptoms and atypical imaging findings which are easily misdiagnosed. There is an urgent need for a noninvasive, rapid and accurate biomarker for distinguishing LC from TB.

METHODS:

ProteomicsCleavage of CAD by caspase-3 determines the cancer cell fate during chemotherapy
Metabolic heterogeneity resulting from the intrinsic heterogeneity of human tumors has been shown to cause a myriad of adverse outcomes of tumor therapy, including resistance to chemotherapy, but the mechanisms inside remain largely unknown. Here, we found that the de novo pyrimidine synthesis pathw...
