Abstract
Cyclophilin A (CypA) is a ubiquitous and highly conserved protein. CypA, the intracellular target protein for the immunosuppressant cyclosporine A (CsA), plays important cellular roles through peptidyl-prolyl cis-trans isomerase (PPIase). Increasing evidence shows that CypA is up-regulated in a variety of human cancers. In addition to being involved in the occurrence and development of multiple tumors, overexpression of CypA has also been shown to be strongly associated with malignant transformation. Surgery, chemotherapy and radiotherapy are the three main treatments for cancer. Chemotherapy and radiotherapy are often used as direct or adjuvant treatments for cancer. However, various side effects and resistance to both chemotherapy and radiotherapy bring great challenges to these two forms of treatment. According to recent reports, CypA can improve the chemosensitivity and/or radiosensitivity of cancers, possibly by affecting the expression of drug-resistant related proteins, cell cycle arrest and activation of the mitogen-activated protein kinase (MAPK) signaling pathways. In this review, we focus on the role of CypA in cancer, its impact on cancer chemotherapeutic and radiotherapy sensitivity, and the mechanism of action. It is suggested that CypA may be a novel potential therapeutic target for cancer chemotherapy and/or radiotherapy.

Direct stimulation of ERBB2 highlights a novel cytostatic signaling pathway driven by the receptor Thr 701 phosphorylation. Sci Rep 2020; 10:16906.

Abstract
ERBB2 is a ligand-less tyrosine kinase receptor expressed at very low levels in normal tissues; when overexpressed, it is involved in malignant transformation and tumorigenesis in several carcinomas. In cancer cells, ERBB2 represents the preferred partner of other members of the ERBB receptor family, leading to stronger oncogenic signals, by promoting both ERK and AKT activation. The identification of the specific signaling downstream of ERBB2 has been impaired by the lack of a ligand and of an efficient way to selectively activate the receptor. In this paper, we found that antibodies (Abs) targeting different epitopes on the ERBB2 extracellular domain foster the activation of ERBB2 homodimers, and surprisingly induce a unique cytostatic signaling cascade promoting an ERK-dependent ERBB2 Thr701 phosphorylation, leading to AKT de-phosphorylation, via PP2A Ser/Thr phosphatases. Furthermore, the immunophilin Cyclophilin A plays a crucial role in this pathway, acting as a negative modulator of AKT de-phosphorylation, possibly by competing with Ser/Thr phosphatases for binding to AKT. Altogether, our data show that Ab recognizing ERBB2 extracellular domain function as receptor agonists, promoting ERBB2 homodimer activation, leading to an anti-proliferative signaling. Thus, the ultimate outcome of ERBB2 activity might depend on the dimerization status: pro-oncogenic in the hetero-, and anti-oncogenic in the homo-dimeric form.

[PMID: 31740398 DOI: 10.1016/j.fsi.2019.11.020] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 11/05/2019] [Accepted: 11/09/2019] [Indexed: 06/10/2023]
Abstract
As a ubiquitously expressed protein, cyclophilin A (CypA) is involved in a variety of pathological process, including immune suppression, inflammation, cell apoptosis, viral infection and stress response. However, the functional roles of CypA were largely unknown in economic marine animals. In this report, a novel CypA gene from sea cucumber Apostichopus japonicus (designated as AjCypA) was cloned and its function roles in immune responses were explored. The full-length cDNA of AjCypA was 1297 bp containing an open reading frame of 489 bp encoding a putative protein of 162 amino acids (aa). A conserved cyclophilin-like domain (CLD) with PPIase signature was located from 5 to 155 aa sequences in AjCypA, in which five necessary aa residues was totally conserved. In healthy sea cucumbers, AjCypA was expressed in all detected tissues, with highly expressed in muscles and weakly expressed in coelomocytes. AjCypA transcripts was significantly induced 8.08-fold and 5.65-fold in coelomocytes when sea cucumbers challenged with Vibrio splendidus in vivo and LPS in vitro, respectively. The expression pattern is similar with the expression of AjRel in the same condition. Moreover, GST pull-down and immunofluorescence analysis both revealed that AjCypA might be interacted with AjRel. Furthermore, AjCypA knockdown not only inhibited the expression of inflammation cytokines, but also suppressed the translocation of AjRel in nucleus induced by LPS. Taken together, our results suggested that AjCypA play key roles in V. splendidus mediated immune responses via suppressing the nuclear translocation of AjRel activity in sea cucumber.

Abstract
Cyclophilin A (CyPA), which is encoded by PPIA, is a ubiquitously expressed intracellular protein and is secreted in response to inflammatory stimuli. CyPA stimulates proinflammatory and apoptosis signaling pathways in vascular smooth muscle cells (VSMCs) and endothelial cells (ECs), promotes VSMC migration and proliferation, EC adhesion molecules expression, and inflammatory cell chemotaxis and apoptosis. Therefore, we sought to study the transcriptional regulation of CyPA, we hypothesized that transcription factor STAT3 regulated CyPA expression and activated vascular ECs in vitro in a CyPA-dependent manner. Using RT-qPCR, immunostaining, luciferase and ChIP assays, we found that STAT3 induced CyPA expression depended on its transcriptional activation by binding to a specific region containing the STAT3-responsive element (SRE) in the CyPA promoter. Moreover, with cell viability and apoptosis assays, we identified STAT3 stimulated CyPA-dependent apoptosis of human umbilical vein ECs in vitro.
