Application

L-Glutamic acid γ-(p-nitroanilide) hydrochloride has been used as a solute carrier family 1 member 5 (SLC1A5) inhibitor:
  • or an inhibitor of the cell membrane glutamine transporter to study the effects of blocking glutamine uptake on esophageal adenocarcinoma (EACC) and thioredoxin-interacting protein (TXNIP)
  • in glutamine ELISA assay to treat confluent differentiated uninfected human colonoid monolayer (HCM) in apical and basolateral compartments to study its effects
  • to study its effect on SLC1A5_var-mediated mitochondrial glutamine transport inhibition
  • to study its effects on cellular glutathione levels, cellular reactive oxygen species (ROS) levels, and mitochondrial ROS levels

Biochem/physiol Actions

L-Glutamyl-p-nitroanilide (GPNA) is commonly used to block the glutamine (Gln) transporter alanine-serine-cysteine transporter 2 (ASCT2). It can also inhibit sodium-dependent and independent amino acid transporters. GPNA, γ-glutamyltransferase (GGT) substrate plays a key role in the hydrolysis of its γ-glutamyl bond and the subsequent release of the chromogen, p-nitroaniline (PNA).

Colonic epithelium-commensal interactions play a very important role in human health and disease development. Colonic mucus serves as an ecologic niche for a myriad of commensals and provides a physical barrier between the epithelium and luminal content, suggesting that communication

In 2017, an estimated 17,000 individuals were diagnosed with esophageal adenocarcinoma (EAC), and less than 20% will survive 5 years. Positron emission tomography avidity is indicative of high glucose utilization and is nearly universal in EAC. TXNIP blocks glucose uptake
