Ren QX, Zhuang QS, Shen GL. Expression and significance of pin1 in the wound healing. Arch Dermatol Res 2024; 316:235. [PMID: 38795154 DOI: 10.1007/s00403-024-03030-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 04/17/2024] [Accepted: 04/26/2024] [Indexed: 05/27/2024]
Abstract
The aim of this study is to delineate the expression patterns of prolyl cis-trans isomerase NIMA-interacting protein 1 (Pin1), Glial cell-derived neurotrophic factor (GDNF), and Angiotensin II (ANG II) during the process of wound repair, and to ascertain the effects of Pin1, GDNF, and ANG II on the healing of wounds in a rat model. A total of 18 rats were allocated into three groups-sham (control), DMSO (vehicle control), and Pin1 inhibitor (treatment with juglone)-with six animals in each group. An animal model of wound healing was established, followed by the intraperitoneal administration of juglone. Tissue samples from the wounds were subsequently collected for histopathological evaluation. Expression levels of Pin1, GDNF, and Ang II were quantified. In addition, an in vitro model of wound healing was created using human umbilical vein endothelial cells (HUVEC), to assess cell proliferation, migration, and tube formation under conditions of juglone pre-treatment. The expression levels of Pin1, GDNF, and ANG II were notably elevated on 7-, and 10- days post-wound compared to those measured on 3-day. Contrastingly, pre-treatment with juglone significantly inhibited the expression of these molecules. Histological analyses, including HE (Hematoxylin and Eosin), Masson's trichrome, and EVG (Elastic van Gieson) staining, demonstrated that vascular angiogenesis, as well as collagen and elastin deposition, were substantially reduced in the juglone pre-treated group when compared to the normal group. Further, immunohistochemical analysis revealed a considerable decrease in CD31 expression in the juglone pre-treatment group relative to the normal control group. Pin1 serves as a pivotal facilitator of wound repair. The findings indicate that the modulation of Pin1, GDNF, and ANG II expression impacts the wound healing process in rats, suggesting potential targets for therapeutic intervention in human wound repair.

Abstract
Epilepsy is a common symptom of many neurological disorders and can lead to neuronal damage that plays a major role in seizure-related disability. The peptidyl-prolyl isomerase Pin1 has wide-ranging influences on the occurrence and development of neurological diseases. It has also been suggested that Pin1 acts on epileptic inhibition, and the molecular mechanism has recently been reported. In this review, we primarily focus on research concerning the mechanisms and functions of Pin1 in neurons. In addition, we highlight the significance and potential applications of Pin1 in neuronal diseases, especially epilepsy. We also discuss the molecular mechanisms by which Pin1 controls synapses, ion channels and neuronal signaling pathways to modulate epileptic susceptibility. Since neurotransmitters and some neuronal signaling pathways, such as Notch1 and PI3K/Akt, are vital to the nervous system, the role of Pin1 in epilepsy is discussed in the context of the CaMKII-AMPA receptor axis, PSD-95-NMDA receptor axis, NL2/gephyrin-GABA receptor signaling, and Notch1 and PI3K/Akt pathways. The effect of Pin1 on the progression of epilepsy in animal models is discussed as well. This information will lead to a better understanding of Pin1 signaling pathways in epilepsy and may facilitate development of new therapeutic strategies.

Abstract
Pin1 belongs to the peptidyl-prolyl cis-trans isomerases (PPIases) superfamily and catalyzes the cis-trans conversion of proline in target substrates to modulate diverse cellular functions including cell cycle progression, cell motility, and apoptosis. Dysregulation of Pin1 has wide-ranging influences on the fate of cells; therefore, it is closely related to the occurrence and development of various diseases. This review summarizes the current knowledge of Pin1 in disease pathogenesis.

A novel controlled release formulation of the Pin1 inhibitor ATRA to improve liver cancer therapy by simultaneously blocking multiple cancer pathways. J Control Release 2018; 269:405-422. [PMID: 29170140 PMCID: PMC6290999 DOI: 10.1016/j.jconrel.2017.11.031] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2017] [Revised: 11/09/2017] [Accepted: 11/19/2017] [Indexed: 12/11/2022]
Abstract
Hepatocellular carcinoma (HCC) is the second leading cause of cancer deaths worldwide largely due to lack of effective targeted drugs to simultaneously block multiple cancer-driving pathways. The identification of all-trans retinoic acid (ATRA) as a potent Pin1 inhibitor provides a promising candidate for HCC targeted therapy because Pin1 is overexpressed in most HCC and activates numerous cancer-driving pathways. However, the efficacy of ATRA against solid tumors is limited due to its short half-life of 45min in humans. A slow-releasing ATRA formulation inhibits solid tumors such as HCC, but can be used only in animals. Here, we developed a one-step, cost-effective route to produce a novel biocompatible, biodegradable, and non-toxic controlled release formulation of ATRA for effective HCC therapy. We used supercritical carbon dioxide process to encapsulate ATRA in largely uniform poly L-lactic acid (PLLA) microparticles, with the efficiency of 91.4% and yield of 68.3%, and ~4-fold higher Cmax and AUC over the slow-releasing ATRA formulation. ATRA-PLLA microparticles had good biocompatibility, and significantly enhanced the inhibitory potency of ATRA on HCC cell growth, improving IC50 by over 3-fold. ATRA-PLLA microparticles exerted its efficacy likely through degrading Pin1 and inhibiting multiple Pin1-regulated cancer pathways and cell cycle progression. Indeed, Pin1 knock-down abolished ATRA inhibitory effects on HCC cells and ATRA-PLLA did not inhibit normal liver cells, as expected because ATRA selectively inhibits active Pin1 in cancer cells. Moreover ATRA-PLLA microparticles significantly enhanced the efficacy of ATRA against HCC tumor growth in mice through reducing Pin1, with a better potency than the slow-releasing ATRA formulation, consistent with its improved pharmacokinetic profiles. This study illustrates an effective platform to produce controlled release formulation of anti-cancer drugs, and ATRA-PLLA microparticles might be a promising targeted drug for HCC therapy as PLLA is biocompatible, biodegradable and nontoxic to humans.
