Endosomal protein expression of γ1-adaptin is associated with tumor growth activity and relapse-free survival in breast cancer. Breast Cancer 2024; 31:305-316. [PMID: 38265632 PMCID: PMC10902087 DOI: 10.1007/s12282-023-01539-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Accepted: 12/20/2023] [Indexed: 01/25/2024]
Abstract
BACKGROUND γ1-Adaptin is a subunit of adaptor protein complex-1 (AP-1), which regulates intracellular transport between the trans-Golgi network (TGN) and endosomes. Since expression levels of AP-1 subunits have been reported to be associated with cell proliferation and cancer malignancy, we investigated the relationships between the immunohistochemical expression of γ1-adaptin and both clinicopathological factors and relapse-free survival (RFS) in breast cancer tissue. MATERIALS AND METHODS SK-BR-3 cell line depleted of γ1-adaptin was used for cell proliferation, migration, and invasion assay. Intracellular localization of γ1-adaptin was examined with immunohistochemistry (IHC) using an antibody against γ1-adaptin, and with double immunohistofluorescence (IHF) microscopy using markers for the TGN and endosome. γ1-Adaptin intensities in IHC samples from 199 primary breast cancer patients were quantified and assessed in relation to clinicopathological factors and RFS. RESULTS Cell growth, migration, and invasion of SK-BR-3 cells were significantly suppressed by the depletion of γ1-adaptin. Although the staining patterns in the cancer tissues varied among cases by IHC, double IHF demonstrated that γ1-adaptin was mainly localized in EEA1-positive endosomes, but not in the TGN. γ1-Adaptin intensity was significantly higher in the tumor regions than in non-tumor regions. It was also higher in patients with Ki-67 (high), ER (-), PgR (-), and HER2 (+). Among subtypes of breast cancer, γ1-adaptin intensity was higher in HER2 than in luminal A or luminal B. The results of the survival analysis indicated that high γ1-adaptin intensity was significantly associated with worse RFS, and this association was also observed in group with ER (+), PgR (+), HER2 (-), Ki-67 (high), or luminal B. In addition, the Cox proportional hazards model showed that high γ1-adaptin intensity was an independent prognostic factor. CONCLUSION These results suggest that the endosomal expression of γ1-adaptin is positively correlated with breast cancer malignancy and could be a novel prognostic marker.

Abstract
Correlation between blood-oxygen-level-dependent (BOLD) and cerebral blood flow (CBF) has been used as an index of neurovascular coupling. Hippocampal BOLD-CBF correlation is associated with neurocognition, and the reduced correlation is associated with neuropsychiatric disorders. We conducted the first genome-wide association study of the hippocampal BOLD-CBF correlation in 4,832 Chinese Han subjects. The hippocampal BOLD-CBF correlation had an estimated heritability of 16.2-23.9% and showed reliable genome-wide significant association with a locus at 3q28, in which many variants have been linked to neuroimaging and cerebrospinal fluid markers of Alzheimer's disease. Gene-based association analyses showed four significant genes (GMNC, CRTC2, DENND4B, and GATAD2B) and revealed enrichment for mast cell calcium mobilization, microglial cell proliferation, and ubiquitin-related proteolysis pathways that regulate different cellular components of the neurovascular unit. This is the first unbiased identification of the association of hippocampal BOLD-CBF correlation, providing fresh insights into the genetic architecture of hippocampal neurovascular coupling.

Uemura T, Suzuki T, Dohmae N, Waguri S. Clathrin adapters AP-1 and GGA2 support expression of epidermal growth factor receptor for cell growth. Oncogenesis 2021; 10:80. [PMID: 34799560 PMCID: PMC8604998 DOI: 10.1038/s41389-021-00367-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 10/20/2021] [Accepted: 10/25/2021] [Indexed: 01/03/2023] Open
Abstract
The role of Golgi/endosome-localized clathrin adapters in the maintenance of steady-state cell surface epidermal growth factor receptor (EGFR) is not well known. Here, we show that EGFR associates preferentially with both AP-1 and GGA2 in vitro. AP-1 depletion caused a reduction in the EGFR protein by promoting its lysosomal degradation. Triple immunofluorescence microscopy and proximity ligation assays demonstrated that the interaction of EGFR with AP-1 or GGA2 occurred more frequently in Rab11-positive recycling endosomes than in Rab5-positive early endosomes. Biochemical recycling assay revealed that the depletion of AP-1 or GGA2 significantly suppressed EGFR recycling to the plasma membrane regardless of the EGF stimulation. Depletion of AP-1 or GGA2 also reduced cell contents of other tyrosine kinases, MET and ErbB4, and therefore, suppressed the growth of H1975 cancer cells in culture and xenograft model. Moreover, AP-1 was expressed in endosomes at higher levels in some cancer tissues. Collectively, these results suggest that AP-1 and GGA2 function in recycling endosomes to retrieve endocytosed EGFR, thereby sustaining its cell surface expression and, consequently, cancer cell growth.

Abstract
The Golgi-localized, gamma-ear containing, ADP-ribosylation factor-binding proteins (GGAs 1, 2, and 3) are multidomain proteins that bind mannose 6-phosphate receptors (MPRs) at the Golgi and play a role, along with adaptor protein complex 1 (AP-1), in the sorting of newly synthesized lysosomal hydrolases to the endolysosomal system. However, the relative importance of the two types of coat proteins in this process is still unclear. Here, we report that inactivation of all three GGA genes in HeLa cells decreased the sorting efficiency of cathepsin D from 97% to 73% relative to wild-type, with marked redistribution of the cation-independent MPR from peripheral punctae to the trans-Golgi network. In comparison, GNPTAB-/- HeLa cells with complete inactivation of the mannose 6-phosphate pathway sorted only 20% of the cathepsin D. We conclude that the residual sorting of cathepsin D in the GGA triple-knockout cells is mediated by AP-1.

Abstract
During myogenesis, myogenic stem cells undergo several sequential events, including cell division, migration, and cell-cell fusion, leading to the formation of multinuclear myotubes, which are the precursors of myofibers. To understand the molecular mechanisms underlying these complex processes, an RNA interference-based gene depletion approach was used. Golgi associated, gamma adaptin ear containing, ARF binding protein 1 (GGA1), a Golgi-resident monomeric clathrin adaptor, was found to be required for the process of myotube formation in C2C12 cells, a cultured murine myoblast cell line. Gga1 mRNA expression was upregulated during myogenesis, and Gga1 depletion prevented the formation of large multi-nucleated myotubes. Moreover, inhibition of lysosomal proteases in Gga1 knockdown myoblasts increased the amount of insulin receptor, suggesting that GGA1 is involved in the cell surface expression and sorting of the insulin receptor. These results suggested that GGA1 plays a significant role in the formation and maturation of myotubes by targeting the insulin receptor to the cell surface to establish functionally mature myofibers.
