Abstract
Transmembrane protein 59 (TMEM59) is a type I transmembrane protein. However, the characterization and functions of TMEM59 in cells are not clear. Our results showed that TMEM59 localizes to vesicular structures. Further co-localization studies illustrated that TMEM59 is mainly distributed in the lysosome and acidic vesicular. TMEM59 movement between the nucleus and cell membrane was observed in living cells expressing TMEM59–EGFP fusion proteins. In addition, cell surface transport of amyloid precursor protein (APP) was significantly inhibited by TMEM59 and increased APP levels in HEK296T cells. TMEM59 also significantly inhibits transport of Rab GDP dissociation inhibitor alpha (GDI1) and Rab GDP dissociation inhibitor beta (GDI2), and further increases expression of GDI1 and GDI2 proteins in the cytoplasm. However, TMEM59 does not affect protein expression and localization of BACE2. These results suggest that TMEM59 may be involved in the packaging of acidic vesicles, modulated transport, and processing of APP, GDI1, and GDI2.

[PMID: 34799992 PMCID: PMC8704163 DOI: 10.1002/cam4.4440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2021] [Revised: 09/15/2021] [Accepted: 10/17/2021] [Indexed: 11/07/2022] Open
Abstract
BACKGROUND Dcf1 has been demonstrated to play vital roles in many CNS diseases, it also has a destructive role on cell mitochondria in glioma cells and promotes the autophagy. Hitherto, it is unclear whether the viability of glioblastoma cells is affected by Dcf1, in particular Dcf1 possesses broad localization on different organelles, and the organelles interaction frequently implicated in cancer cells survival. METHODS Surgically excised WHO grade IV human glioblastoma tissues were collected and cells isolated for culturing. RT-PCR and DNA sequencing assay to estimate the abundance and mutation of Dcf1. iTRAQ sequencing and bioinformatic analysis were performed. Subsequently, immunoprecipitation assay to evaluate the degradation of HistoneH2A isomers by UBA52 ubiquitylation. Transmission electron microscopy (TEM) was applied to observe the structure change of mitochondria and autophagosome. Organelle isolated assay to determine the distribution of protein. Cell cycle and apoptosis were evaluated by flow cytometric assays. RESULTS Dcf1 was downregulated in WHO grade IV tumor without mutation, and overexpression of Dcf1 was found to significantly regulate glioblastoma cells. One hundred and seventy-six differentially expressed proteins were identified by iTRAQ sequencing. Furthermore, we confirmed that overexpression of Dcf1 destabilized the structure of the nucleosome via UBA52 ubiquitination to downregulate HistoneH2A.X but not macroH2A or HistoneH2A.Z, decreased the mitochondrial DNA copy number and inhibited the mitochondrial biogenesis, thus causing mitochondrial destruction and dysfunction in order to supply cellular energy and induce mitophagy preferentially but not apoptosis. Dcf1 also has disrupted the integrity of lysosomes to block autolysosome degradation and autophagy and to increase the release of Cathepsin B and D from lysosomes into cytosol. These proteins cleaved and activated BID to induce glioblastoma cells apoptosis. CONCLUSIONS In this study, we demonstrated that unmutated Dcf1 expression is negatively related to the malignancy of glioblastoma, Dcf1 overexpression causes nucleosomes destabilization, mitochondria destruction and dysfunction to induce mitophagy preferentially, and block autophagy by impairing lysosomes to induce apoptosis in glioblastoma.

Abstract
Neuropeptide Y (NPY), one of the most abundant neuropeptides in the body, is widely expressed in the central and peripheral nervous systems and acts on the cardiovascular, digestive, endocrine, and nervous systems. NPY affects the nutritional and inflammatory microenvironments through its interaction with immune cells, brain-derived trophic factor (BDNF), and angiogenesis promotion to maintain body homeostasis. Additionally, NPY has great potential for therapeutic applications against various diseases, especially as an adjuvant therapy for stem cells. In this review, we discuss the research progress regarding NPY, as well as the current evidence for the regulation of NPY in each microenvironment, and provide prospects for further research on related diseases.

TMEM59 interacts with TREM2 and modulates TREM2-dependent microglial activities. Cell Death Dis 2020; 11:678. [PMID: 32826884 PMCID: PMC7442838 DOI: 10.1038/s41419-020-02874-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 08/01/2020] [Accepted: 08/03/2020] [Indexed: 12/20/2022]
Abstract
The surface receptor triggering receptor expressed on myeloid cells 2 (TREM2) plays a crucial role in maintaining a multitude of microglial activities, such as survival, proliferation, migration, metabolism, inflammation, and phagocytosis. However, the molecular mechanisms underlying TREM2-mediated microglial activities remain largely elusive. Herein, we found that TREM2 interacted with the type I transmembrane protein TMEM59, whose expression could facilitate autophagic flux through its carboxyl-terminus. TMEM59 expression was decreased upon lipopolysaccharide treatment. While downregulation of TMEM59 promoted anti-inflammatory factor expression and attenuated lipopolysaccharide treatment-induced inflammation. Importantly, we found that overexpression of TREM2 reduced TMEM59 protein levels through promoting its degradation, whereas TMEM59 levels were elevated in Trem2-deficient microglia. Finally, impaired survival, proliferation, migration, and phagocytosis, as well as dysregulated autophagy and metabolism in Trem2-deficient microglia were attenuated upon TMEM59 silencing. Together, our findings reveal a novel function of TREM2 in mediating TMEM59 protein degradation and demonstrate the importance of TMEM59 homeostasis in maintaining TREM2-mediated microglial activities.

Abstract
The gut-brain communication is increasingly being recognized as a profound effector on Parkinson's disease (PD). Gut microbiota changes have become the focus of attention. However, the mechanism leading to changes in the gut microbiota is not clear. In the present study, we found that knockout of Dcf1 (Dcf1-/-) caused changes in the gut microbiota in mice. Results indicated that the increased Proteobacteria (phylum-level) and decreased Prevotellaceae (family-level) in the microbiota composition of Dcf1-/- (KO) mice, which is consistent with the situation of PD patients. On species-level, Prevotellaceae_UCG-001 and Helicobacter_ganmani were significantly different between KO and WT mice, suggesting glycolipid metabolism disorders and inflammatory lesions in KO mice. In the behavior of Y-maze and Open field test, KO mice showed typical PD symptoms such as memory deficits, slowness of movement and anxiety. Further Nissl staining of brain tissue sections confirmed that the deletion of Dcf1 caused damage to amygdala neurons. These results provide a new mechanism for understanding gut microbiota changes, and provide a new basis for PD treatment from a new perspective of Gut-brain axis.

Abstract
Neuroblastoma (NB) is the most common extracranial solid tumor that affects mainly children and has extremely high mortality and recurrence rates. A previous study revealed that dendritic cell factor 1 (DCF1), also called transmembrane protein 59, could activate apoptosis in glioma cells. In the present study, we applied immunofluorescence, western blot analysis, flow cytometry and cell tumorigenicity to investigate the DCF1 mechanisms involved in NB apoptosis. DCF1 was overexpressed in Neuro-2a and SK-N-SH cells through instantaneous transfection. The data revealed that overexpression of DCF1 could inhibit cell proliferation, migration, invasion and promote cell apoptosis in vitro, and suppress NB growth in vivo. The ERK1/2 signaling pathway, which promotes cell survival, was the target of DCF1 in neuroblastoma cells. All the results indicated that DCF1 could be a potential therapeutic target for the understanding and treatment of NB.
