Lysophosphatidic acid (LPA) is an extracellular lipid mediator that regulates nervous system development and functions acting through G protein-coupled receptors (GPCRs). Here we explore the crosstalk between LPA1 receptor ... -
Glutaminase isoforms expression switches microRNA levels and oxidative status in glioblastoma cells.
De los Santos-Jiménez, Juan; Campos-Sandoval, José Ángel; Márquez-Torres, Clara; Urbano-Polo, Nieves; Brøndegaard, David; Martín-Rufián, Mercedes; Lobo, Carolina; Peñalver Alonso, Ana; Gómez García, María del Carmen; Martín-Campos, Janet; Cardona Ramírez, Carolina; Castilla, Laura; Da-Costa-Souza, Felipe; Cheng, Tzuling; Segura-Checa, Juan Antonio; Alonso-Carrión, Francisco José; Curi, Rui; Colquhoun, Alison; DeBerardinis, Ralph J; Márquez-Gómez, Javier; Mates-Sánchez, José Manuel[et al.] (BMC, 2021-02-20)
Glutaminase isoenzymes GLS and GLS2 play apparently opposing roles in cancer: GLS acts as an oncoprotein, while GLS2 (GAB isoform) has context specific tumour suppressive activity. Some microRNAs (miRNAs) have been implicated ... -
