J Cell Mol Med 2022; 26:1128-1143. [PMID: 35001521 PMCID: PMC8831953 DOI: 10.1111/jcmm.17166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 12/14/2021] [Accepted: 12/21/2021] [Indexed: 11/29/2022] Open
Abstract
Acute myeloid leukaemia (AML) is a biologically heterogeneous disease with an overall poor prognosis; thus, novel therapeutic approaches are needed. Our previous studies showed that 4-amino-2-trifluoromethyl-phenyl retinate (ATPR), a new derivative of all-trans retinoic acid (ATRA), could induce AML cell differentiation and cycle arrest. The current study aimed to determine the potential pharmacological mechanisms of ATPR therapies against AML. Our findings showed that E2A was overexpressed in AML specimens and cell lines, and mediate AML development by inactivating the P53 pathway. The findings indicated that E2A expression and activity decreased with ATPR treatment. Furthermore, we determined that E2A inhibition could enhance the effect of ATPR-induced AML cell differentiation and cycle arrest, whereas E2A overexpression could reverse this effect, suggesting that the E2A gene plays a crucial role in AML. We identified P53 and c-Myc were downstream pathways and targets for silencing E2A cells using RNA sequencing, which are involved in the progression of AML. Taken together, these results confirmed that ATPR inhibited the expression of E2A/c-Myc, which led to the activation of the P53 pathway, and induced cell differentiation and cycle arrest in AML.

Osana S, Kitajima Y, Suzuki N, Xu Y, Murayama K, Nagatomi R. siRNA knockdown of alanine aminopeptidase impairs myoblast proliferation and differentiation. Exp Cell Res 2020; 397:112337. [PMID: 33091420 DOI: 10.1016/j.yexcr.2020.112337] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 10/15/2020] [Accepted: 10/18/2020] [Indexed: 12/20/2022]
Abstract
A large number of intracellular proteins are degraded by the ubiquitin-proteasome system, one of the major protein degradation pathways. It produces peptides of several different sizes through protein degradation, and these peptides are rapidly degraded into free amino acids by various intracellular aminopeptidases. Previously, we reported that the activity of proteasomes and aminopeptidases in the proteolysis pathway are necessary for myoblast proliferation and differentiation. However, the detailed function of intracellular aminopeptidases in myoblast proliferation and differentiation has not yet been elucidated. In this study, we focused on alanine aminopeptidase (APN) and investigated the function of APN in C2C12 myoblast proliferation and differentiation. In myoblasts and myotubes, APN was mainly localized in the cell membrane as well as expressed at low levels in the cytoplasm and nucleus. The reduction of the APN enzymatic activity impaired the cell cycle progression in C2C12 myoblasts. In addition, apoptosis was induced after APN-knockdown. Finally, myogenic differentiation was also delayed in the APN-suppressed myoblasts. These findings indicate that APN is required for myoblast proliferation and differentiation.

Inhibition of the proliferation, migration, and invasion of human breast cancer cells by leucine aminopeptidase 3 inhibitors derived from natural marine products. Anticancer Drugs 2020; 31:60-66.

Abstract
Leucine aminopeptidase 3 is involved in the progression and metastasis of several cancers. This study aimed to screen anti-tumor lead compounds targeting leucine aminopeptidase 3. The compounds' suppression effect on enzyme activity and anti-tumor activity were evaluated through a series of assays. Leucine aminopeptidase 3 overexpression K562 cells were used as an enzyme source to screen 43 natural marine compounds. Compounds 5 and 6 exhibited high suppression effect on leucine aminopeptidase 3 activity. Cell activity tests indicated that both compounds have an anti-proliferative effect on triple-negative breast cancer cells. Wound healing assay and transwell invasion assay showed that both compounds could inhibit the migration and invasion of breast cancer cells. Immunoblot analysis exhibited that both compounds could downregulate the expression of metastasis-related proteins fascin and matrix metalloproteinase-2/9. A molecular dynamic simulation process was applied to discover the key features of compounds 5 and 6 in binding to leucine aminopeptidase 3 active site. This study described the anti-tumor effects of two leucine aminopeptidase 3 small molecule inhibitors. Taken together, compounds 5 and 6 could be used as anti-tumor lead compounds targeting leucine aminopeptidase 3.
