Recent Research Progress
The β4-galactosyltransferase (B4GALT) family has seven members and each of those members possesses distinct biological functions on account of different receptor specificity, tissue distribution, and temporal expression. B4GALT1 binds galactose to the N-acetylglucosamine outer arm in the N-linked oligosaccharide of IgG, and the B4GALT1 level is continuously linked to the continuation of the terminal galactose in IgG, which is associated with an adaptive immune response. The importance of glycan β4-galactosylation of glycans is well known, and the galactosylation can be part of many biological activities, such as cancer progression. Changes in expression of B4GALT1 have been documented in certain types of cancer, such as breast cancer, colon cancer, hepatocellular cancer, lung cancer, leukemia, neuroblastoma and prostate cancer, and are connected to cancer cell proliferation, invasion, metastasis and Resistance drug.
B4GALT1 and MIBC
The fourth most commonly diagnosed cancer, bladder cancer has an occurrence rate of about 7%, is the eighth most common cause of male death (about 4%). Recent studies have shown that B4GALT1 expression was not associated with clinical prognostic markers, but it was connected to overall survival (OS). In addition, high levels of B4GALT1 expression were independent indicators of poor OS. Inclusion of B4GALT1 in the prognostic model showed higher prediction accuracy than the primary model. Moreover, there was a positive Pearson correlation between B4GALT1 expression and inhibitory receptor ligand expression, such as programmed death-ligand 1 (PD-L1) and Cytotoxic T-lymphocyte-associated protein 4 (CTLA4). Most significantly, the advantage of adjuvant chemotherapy (ACT) noted in patients with low B4GALT1 expression in pT3/4 or N+ bladder cancer was greater than in patients with high B4GALT1 expression. In conclusion, B4GALT1 may be a prognostic factor for muscle invasive bladder cancer (MIBC), which may be a predictive marker for ACT in patients with pT3 / 4 or N+. The high expression of B4GALT1 can lead to a more effective immunosuppressive microenvironment, which helps to better select the combination of chemotherapy and immunotherapy in patients with MIBC.
B4GALT1 and CML
Abnormal expression of suppressor of cytokine signaling 3 (SOCS3) is associated with myeloproliferative neoplasms and SOCS3 plays an important role in the pathogenesis of chronic myeloid leukemia (CML). Recent studies have shown that miR-124-3p was obviously up-regulated by SOCS3 overexpression. In turn, changes in the expression level of miR-124-3p affected the effect of SOCS3 on CML cells. Furthermore, B4GALT1 is a multidrug resistance gene that is a target gene for the SOCS3 / miR-124-3p axis. These findings demonstrated the existence of molecular networks involved in the dysregulation of SOCS3, miR-124-3p and B4GALT1, which may provide new insights into tumor biology and present a useful target for therapeutic interference of CML under certain circumstances.
B4GALT1 and ccRCC
Clear cell renal cell carcinoma (ccRCC) is the most common subtype of kidney cancer, and its incidence increases by 2.5% per year worldwide. A recent association between high expression of B4GALT1 and increased risk of death in patients with non-metastatic ccRCC after surgery has been reported. High B4GALT1 expression was positively correlated with histological necrosis, tumor T stage, and Fuhrman grading, which strongly suggested that B4GALT1 plays a key role in ccRCC development and progression. What’s more, the accuracy of the UISS (University of California Integrated Staging System) and SSIGN (Mayo Clinic stage, size, grade and necrosis score) prognostic models was improved when B4GALT1 expression was added. In summary, the current study identified B4GALT1 expression as a potential independent adverse prognostic indicator for OS in patients with non-metastatic ccRCC.
In conclusion, B4GALT1 expression plays an important role in the pathogenesis of various cancers. Combining B4GALT1 expression with a conventional prognostic model can improve the prognosis accuracy. Further research may attempt to verify whether B4GALT1 can be used as a new therapeutic target.
