Abstract
Mutations in the genes of tumor cells and the disorder of immune microenvironment are the main factors of tumor development. The sensitivity of tumor cells to chemotherapy drugs affect the treatment of tumor. Nuclear transcription factor E4BP4 is dysregulated in a variety of malignant tumors. It can suppress the transcription of NFKBIA, RASSF8, SOSTDC1, FOXO-induced genes (TRAIL, FAS, GADD45a and GADD45b) and Hepcidin, up-regulate RCAN1-1 and PRNP, activate mTOR and p38 in cancer cells. Also, E4BP4 can regulate tumor immune microenvironment. TGFb1/Smad3/E4BP4/ IFNγ axis in NK cells plays an important role in antitumor immunotherapy. Over expression of E4BP4 inhibited the development of Th17 cells by directly binding to the RORγt promoter. Moreover, recent studies have shown that E4BP4 inhibited the expression of multidrug resistance genes. In this review, we summarize the molecular mechanism of E4BP4 in cancer cellular process, the effects of E4BP4 in cancer immunotherapy and antitumor drug resistance, to provide theoretical basis for tumor treatment strategies targeting E4BP4.

Abstract
Tumour necrosis factor receptor-associated factor 4 (TRAF4) is a member of the TRAF protein family, a cytoplasmic bridging molecule closely associated with various immune functions. The physiological processes of TRAF4 are mainly involved in embryonic development, cell polarity, cell proliferation, apoptosis, regulation of reactive oxygen species production. TRAF4 is overexpressed in a variety of tumors and regulates the formation and development of a variety of tumors. In this review, we summarize the physiological and pathological regulatory functions of TRAF4 and focus on understanding the biological processes involved in this gene, to provide a reference for further studies on the role of this gene in tumorigenesis and development.

Abstract
Adipogenesis is mediated by glucocorticoids via transcriptional regulation of glucocorticoid receptor (GR) target genes. However, the mechanism by which GR participates in adipogenesis has hitherto been poorly characterized. In this study, E4 promoter-binding protein 4 (E4BP4) was found to have a critical role in adipogenic differentiation of preadipocytes. Gain-of-function and loss-of-function studies revealed that E4BP4 acts as a positive regulator of adipogenesis in 3T3-L1 cells. E4BP4 was markedly induced by glucocorticoid (dexamethasone) via GR and cAMP response element-binding protein (CREB) during adipogenesis. Knockdown of E4BP4 abolished dexamethasone-induced adipogenesis, and overexpression of E4BP4 partially accounted for the actions of dexamethasone in adipogenic differentiation. Promoter deletion analysis confirmed that E4BP4 transcriptionally represses COX2 promoter activity, whereas COX2 overexpression reversed the acceleration of E4BP4 in adipogenesis. Thus, E4BP4 acts as a key pro-adipogenic transcription factor by trans-repressing COX2 in glucocorticoid-associated adipocyte differentiation.

Abstract
The aging kidney undergoes structural and functional alterations which make it more susceptible to drug-induced acute kidney injury (AKI). Previous studies in our lab have shown that the expression of α(E)-catenin is decreased in aged kidney and loss of α(E)-catenin potentiates AKI-induced apoptosis, but not necrosis, in renal tubular epithelial cells (NRK-52E cells). However, the specific apoptotic pathway underlying the increased AKI-induced cell death is not yet understood. In this study, cells were challenged with nephrotoxicant cisplatin to induce AKI. A ~5.5-fold increase in Fas expression in C2 (stable α(E)-catenin knockdown) relative to NT3 (non-targeted control) cells was seen. Increased caspase-8 and -9 activation was induced by cisplatin in C2 as compared to NT3 cells. In addition, decreased Bcl-2 expression and increased BID cleavage and cytochrome C release were detected in C2 cells after cisplatin challenge. Treating the cells with cisplatin, in combination with a Bcl-2 inhibitor, decreased the viability of NT3 cells to the same level as C2 cells after cisplatin. Furthermore, caspase-3/-7 activation is blocked by Fas, caspase-8, caspase-9 and pan-caspase inhibitors. These inhibitors also completely abolished the difference in viability between NT3 and C2 cells in response to cisplatin. These results demonstrate a Fas-mediated apoptotic signaling pathway that is enhanced by the age-dependent loss of α(E)-catenin in renal tubule epithelial cells.

Biochem Biophys Res Commun 2015; 463:1291-6.

Abstract
Glucocorticoids (GCs) are known to induce apoptosis of leukemia cells via gene regulatory changes affecting key pro-and anti-apoptotic genes. Three genes previously implicated in GC-evoked apoptosis in the CEM human T-cell leukemia model, RCAN1, E4BP4 and BIM, were studied in a panel of human lymphoid and myeloid leukemia cell lines. Of the two RCAN1 transcripts, the synthetic GC Dexamethasone (Dex) selectively upregulates RCAN1-1, but not RCAN1-4, in GC-susceptible Sup-B15, RS4;11, Kasumi-1 cells but not in GC-resistant Sup T1 and Loucy cells. E4BP4 and BIM regulation correlated with that of RCAN1-1. A putative GRE and four EBPREs were identified within 1500bp upstream from the transcription start site of RCAN1-1. GC-refractory CEM C1-15 cells sensitized to GC-evoked apoptosis by ectopic E4BP4 expression, CEM C1-15mE#3, showed restored RCAN1-1 upregulation, suggesting that RCAN1-1 is a downstream target of E4BP4. A model for coordinated regulation of RCAN1-1, E4BP4 and BIM, and their role in GC-evoked apoptosis is proposed.
