Here, we investigated the relationship between the attenuation of lung cancer growth due to oral administration of Euglena gracilis water extract (EWE) and T cell stimulation. Orally administered EWE was revealed to increase PD-1 and PD-L1 mRNA and proteins primarily in tumor-infiltrating lymphocytes (TILs), which was correlated with a significant decrease in the tumor weights in mice. A combination treatment with EWE and anti-PD-1 antibody significantly decreased the growth of murine lung tumors more than treatment with either alone by increasing the number of TILs and attenuating T cell exhaustion.

Neurotox Res

January 2025

Molecular Neuropsychiatry Section, Intramural Research Program, NIH/ NIDA, 21224, Baltimore, MD, U.S.A.

To identify factors involved in methamphetamine (METH) neurotoxicity, we comprehensively searched for genes which were differentially expressed in mouse striatum after METH administration using differential display (DD) reverse transcription-PCR method and sequent single-strand conformation polymorphism analysis, and found two DD cDNA fragments later identified as mRNA of Nedd4 (neural precursor cell expressed developmentally downregulated 4) WW domain-binding protein 5 (N4WBP5), later named Nedd4 family-interacting protein 1 (Ndfip1). It is an adaptor protein for the binding between Nedd4 of ubiquitin ligase (E3) and target substrate protein for ubiquitination. Northern blot analysis confirmed drastic increases in Ndfip1 mRNA in the striatum after METH injections, and in situ hybridization histochemistry showed that the mRNA expression was increased in the hippocampus and cerebellum at 2 h-2 days, in the cerebral cortex and striatum at 18 h-2 days after single METH administration.
