Both GLS silencing and GLS2 overexpression synergize with oxidative stress against proliferation of glioma cells.
Martín-Rufián, Mercedes; Nascimento-Gomes, Renata; Higuero, Ana; Crisma, Amanda R.; Campos-Sandoval, José A.; Gómez-García, María C.; Cardona, Carolina; Cheng, Tzuling; Lobo, Carolina; Segura-Checa, Juan Antonio; Alonso-Carrión, Francisco José; Szeliga, Monika; Albrecht, Jan; Curi, Rui; Márquez-Gómez, Javier; Colquhoun, Alison; DeBerardinis, Ralph J; Mates-Sánchez, José Manuel[et al.] (Springer Nature, 2014)Mitochondrial glutaminase (GA) plays an essential role in cancer cell metabolism, contributing to biosynthesis, bioenergetics, and redox balance. Humans contain several GA isozymes encoded by the GLS and GLS2 genes, but ... -
Design and generation of a glutaminase GLS2 conditional knockout mice
Peñalver, Ana; Tosina, Marta; Martín-Rufián, Mercedes; Campos-Sandoval, José Ángel; Alonso-Carrión, Francisco José; Segura-Checa, Juan Antonio; Mates-Sánchez, José Manuel; Ramírez, Miguel Ángel; Gutiérrez-Adán, Alfonso; Márquez-Gómez, Javier[et al.] (2014-10-04)Mammalian glutaminase (GA; EC 3.5.1.2) is the main enzyme involved in brain generation of glutamate (Glu). This amino acid acts as an excitatory neurotransmitter within the CNS, and it is also implicated in behavioral ... -

Expression of Gls and Gls2 glutaminase isoforms in astrocytes
Cardona, Carolina; Sánchez-Mejías, Elisabeth; Dávila-Cansino, José Carlos; Martín-Rufián, Mercedes; Campos-Sandoval, José Ángel; Vitorica, Javier; Alonso-Carrión, Francisco José; Mates-Sánchez, José Manuel; Segura-Checa, Juan Antonio; Norenberg, Michael D.; Rama Rao, Kakulavarapu V.; Jayakumar, Arumugan R.; Gutiérrez-Pérez, Antonia; Márquez-Gómez, Javier[et al.] (Wiley, 2015-03)The expression of glutaminase in glial cells has been a controversial issue and matter of debate for many years. Actually, glu-taminase is essentially considered as a neuronal marker in brain. Astrocytes are endowed with ... -

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 ... -
Mammalian Glutaminase Gls2 Gene Encodes Two Functional Alternative Transcripts by a Surrogate Promoter Usage Mechanism.
Martín-Rufián, Mercedes; Tosina, Marta; Campos-Sandoval, José Ángel; Manzanares, Elisa; Lobo, Carolina; Segura-Checa, Juan Antonio; Alonso-Carrión, Francisco José; Mates-Sánchez, José Manuel; Márquez-Gómez, Javier[et al.] (PLOS, 2012-06-05)Glutaminase is expressed in most mammalian tissues and cancer cells, but the regulation of its expression is poorly understood. An essential step to accomplish this goal is the characterization of its species- and cell-specific ... -
Nuclear Translocation of Glutaminase GLS2 in Human Cancer Cells Associates with Proliferation Arrest and Differentiation
López de la Oliva, Amada; Campos-Sandoval, José A.; Gómez-García, María Carmen; Cardona, Carolina; Martín-Rufián, Mercedes; Sialana, Fernando J.; Castilla, Laura; Bae, Narkhyun; Lobo, Carolina; Peñalver, Ana; García-Frutos, Marina; Carro, David; Enrique, Victoria; Paz-Gutiérrez, José Carlos; Mirmira, Raghavendra G.; Gutiérrez, Antonia; Alonso-Carrión, Francisco José; Segura-Checa, Juan Antonio; Mates-Sánchez, José Manuel; Lubec, Gert; Márquez-Gómez, Javier[et al.] (Nature Portfolio, 2020-02-10)Glutaminase (GA) catalyzes the first step in mitochondrial glutaminolysis playing a key role in cancer metabolic reprogramming. Humans express two types of GA isoforms: GLS and GLS2. GLS isozymes have been consistently ... -
Ratones knock-out del receptor lpa1 de ácido lisofosfatídico presentan un acusado déficit de la isoenzima glutaminasa KGA (GLS) y una morfología alterada en las espinas dendríticas de hipocampo y corteza
