Esophageal cancer (EC) is one of the most common highly malignant tumors of the digestive system, with a poor prognosis under current treatment regimens. Nucleolin (NCL) is overexpressed in many tumors, and drugs specifically targeting NCL may offer a promising strategy for treating esophageal cancer. Here, we designed and prepared a novel aptamer-conjugated drug targeting NCL by AS1411 aptamer-human serum albumin (HSA)-the apoprotein of lidamycin (LDP)-active enediyne chromophore (AE), in order to achieve targeted treatment of esophageal cancer.

Alzheimer's disease (AD) is a prominent neurodegenerative disorder affecting the central nervous system in the elderly. Current understanding of AD primarily centers on the gradual decline in cognitive and memory functions, believed to be influenced by factors including mitochondrial dysfunction, β-amyloid aggregation, and neuroinflammation. Emerging research indicates that neuroinflammation plays a significant role in the development of AD, with the inflammasome potentially mediating inflammatory responses that contribute to neurodegeneration.

Na-K-Cl cotransporters functions as an anion importers, regulating trans-epithelial chloride secretion, cell volume, and renal salt reabsorption. Loop diuretics, including furosemide, bumetanide, and torsemide, antagonize both NKCC1 and NKCC2, and are first-line medicines for the treatment of edema and hypertension. NKCC1 activation by the molecular crowding sensing WNK kinases is critical if cells are to combat shrinkage during hypertonic stress; however, how phosphorylation accelerates NKCC1 ion transport remains unclear.

A phenotype-based AI pipeline outperforms human experts in differentially diagnosing rare diseases using EHRs.

NPJ Digit Med

January 2025

Department of Computer Science and Technology & Institute for Artificial Intelligence & BNRist, Tsinghua University, Beijing, China.

Rare diseases, affecting ~350 million people worldwide, pose significant challenges in clinical diagnosis due to the lack of experienced physicians and the complexity of differentiating between numerous rare diseases. To address these challenges, we introduce PhenoBrain, a fully automated artificial intelligence pipeline. PhenoBrain utilizes a BERT-based natural language processing model to extract phenotypes from clinical texts in EHRs and employs five new diagnostic models for differential diagnoses of rare diseases.
