26828272 GGCT plays a critical role in glioma cell proliferation and may be a potential cancer therapeutic target.
26339607 GGCT is promising as a diagnostic marker and a therapeutic target for various cancers. This review summarizes these interesting findings.
25941902 GGCT plays a critical role in lung cancer cell proliferation.
25818003 G6PD, GGCT, IDH1, isocitrate dehydrogenase 2 (NADP+,mitochondrial) (IDH2) and glutathione S-transferase pi 1(GSTP1), five of the critical components of GSH pathway, contribute to chemoresistance.
24342434 increased expression of GGCT was a common event among invasive esophageal squamous cell carcinoma tissues regardless of the depth of invasion. Lymph node metastasis and tumor differentiation correlated with GGCT expression
23853312 Transcriptional silencing of the C7orf24 gene in the non-malignant cells is elicited through heterochromatin formation in its promoter region.
23513927 C7orf24 has been recognized as a potent marker for bladder and breast cancers. Studies on the role of gamma-glutamylcyclotransferace may aid in the control of malignant transformation of these cancers.
22205682 GGCT may be a biomarker of tumors in a limited range of organs.
20527979 C7orf24 overexpression defines a subgroup of breast tumors with poor clinical outcome.

20406964 Observational study of gene-disease association. (HuGE Navigator)
19423540 Observational study of gene-disease association. (HuGE Navigator)
18515354 The GGCT gene is located on chromosome 7p14-15 and consists of four exons that span 8 kb, the primary sequence is 188 amino acids in length and is unlike any protein of known function
17932939 presence of extra electron density/ligands and conservation at the sequence and structure levels, it is likely that the cavity has a crucial role in the function of LOC79017 and its structural neighbors possibly as an active site or ligand-binding site
16765912 CRF21 might play an important role in the induction of apoptosis by GGO in leukemia U937 cells.
