ASCT2-mediated glutamine uptake promotes Th1 differentiation via ROS-EGR1-PAC1 pathway in oral lichen planus

29 views | Nov 11 2023

The study reveals that glutamine uptake mediated by ASCT2 plays a pivotal role in promoting Th1 differentiation through a ROS-EGR1-PAC1 pathway in oral lichen planus, suggesting that targeting ASCT2 could be a potential therapeutic approach for T cell-mediated autoimmune diseases by restoring redox balance.

Selective Inhibition of L-type Amino Acid Transporter 1 Suppresses Cell Proliferation in Ovarian Clear Cell Carcinoma

23 views | Aug 20 2023

Selective inhibition of L-type amino acid transporter 1 (LAT1) using nanvuranlat (JPH203) effectively suppresses cell proliferation via the mTOR pathway by inhibiting leucine uptake in ovarian clear cell carcinoma (OCCC), suggesting LAT1 as a potential therapeutic target for this aggressive ovarian cancer.

Small molecule inhibitors provide insights into the relevance of LAT1 and LAT2 in materno-foetal amino acid transport

299 views | Nov 04 2020

Jonas Zaugg et al. thought that differential specificity of the applied inhibitors allowed for estimation of the contribution of LAT1 and LAT2 in materno-foetal AA transfer and their potential impact in pregnancy diseases associated with impaired foetal growth. [Read the Full Post]

JPH203, a selective L-type amino acid transporter 1 inhibitor, induces mitochondria-dependent apoptosis in Saos2 human osteosarcoma cells

443 views | Jan 08 2020

Choi DW et al. suggested that the inhibition of LAT1 activity via JPH203, which may act as a potential novel anti-cancer agent, leads to apoptosis mediated by the mitochondria-dependent intrinsic apoptotic signaling pathway by inducing the intracellular depletion of neutral amino acids essential for cell growth in Saos2 human osteosarcoma cells.

Inhibition of the amino-acid transporter LAT1 demonstrates anti-neoplastic activity in medulloblastoma

485 views | Aug 10 2019

Cormerais Y et al. demonstrated that a long-term treatment with JPH203 does not lead to resistance in MB cells. Therefore, this study suggests that targeting LAT1 with JPH203 is a promising therapeutic approach for MB treatment. [Read the Full Post]
