Distinguishing between Folate Receptor-α-mediated Transport and Reduced Folate Carrier-mediated Transport in L1210 Leukemia Cells [PDF]

Journal of Biological Chemistry, 1995
L1210 leukemia cells transport reduced folates and methotrexate via a well defined reduced folate carrier system and, in the absence of low folate selective pressure, do not express an alternate endocytotic route mediated by cell surface folate receptors.

Decoding the Integrated Stress Response of Pancreatic Cancer: Identifying a Serine‐dependent Tumor Subset Under Metabolic Relationships With CAFs.

Advanced Science, EarlyView.
Researchers identified a pancreatic cancer subset with low global protein synthesis but heightened translation of stress‐response genes like ATF4, rendering cells resistant to chemotherapy and apoptosis. These tumors depend on serine and cysteine from surrounding cancer‐associated fibroblasts (CAFs), which shift to produce serine by curbing collagen ...

Polymorphisms in thymidylate synthase and reduced folate carrier (SLC19A1) genes predict survival outcome in advanced non-small cell lung cancer patients treated with pemetrexed-based chemotherapy

Oncology Letters, 2013
The aim of this study was to evaluate the association between thymidylate synthase (TS), methylenetetrahydrofolate reductase (MTHFR) and reduced folate carrier (SLC19A1) gene polymorphisms and the treatment efficacy of pemetrexed-based chemotherapy in ...

Efficient delivery of methotrexate to MDA-MB-231 breast cancer cells by a pH-responsive ZnO nanocarrier

Scientific Reports, 2023
Methotrexate (MTX), an efficient chemotherapy medication is used in treating various malignancies. However, the breast cancer cell line MDA-MB-231 has developed resistance to it due to low levels of the MTX transport protein, and reduced folate carrier ...

Ultrasound Controlled‐Release Hydrogel Promotes Diabetic Wound Healing via Neuroimmune Modulation and Synergistic ROS Scavenging

Advanced Science, EarlyView.
This study presents an ultrasound‐responsive hydrogel (MCF@CA) that co‐delivers a neuropeptide (CGRP) and a ROS‐scavenging manganese porphyrin to diabetic wounds. The system restores neuro‐immune communication, reprograms macrophages toward an anti‐inflammatory phenotype, and clears excess ROS, thereby accelerating wound closure and promoting mature ...

Targeting the Mapk13‐Tcf1‐Slc7a5 Axis via One‐Carbon Metabolic Regulation to Prevent Chronic Allograft Vasculopathy

Advanced Science, EarlyView.
This study emphasizes the role of the Mapk13‐Tcf1‐Slc7a5‐methionine metabolism axis in stem‐like CD4+ T cells. Moreover, it uncovers the mechanism through which limiting one‐carbon metabolism in CD4+ stem‐like T cells suppresses the tide of chronic allograft vasculopathy, offering potential targets to promote long‐term graft survival.

Advancing Precision Nutrition Through Multimodal Data and Artificial Intelligence

Advanced Science, EarlyView.
Individual responses to food vary dramatically, challenging traditional dietary advice. This review explores how the unique genetic makeup, gut microbiome, and brain activity shape host metabolic health. We examine how artificial intelligence integrates these multimodal data to predict individualized dietary needs, moving beyond one‐size‐fits‐all ...
