Abstract
Protein Arginine Methyltransferases (PRMTs) are a family of enzymes regulating protein arginine methylation, which is a post-translational modification crucial for various cellular processes. Recent studies have highlighted the mechanistic role of PRMTs in cancer pathogenesis, immunotherapy, and drug resistance. PRMTs are involved in diverse oncogenic processes, including cell proliferation, apoptosis, and metastasis. They exert their effects by methylation of histones, transcription factors, and other regulatory proteins, resulting in altered gene expression patterns. PRMT-mediated histone methylation can lead to aberrant chromatin remodeling and epigenetic changes that drive oncogenesis. Additionally, PRMTs can directly interact with key signaling pathways involved in cancer progression, such as the PI3K/Akt and MAPK pathways, thereby modulating cell survival and proliferation. In the context of cancer immunotherapy, PRMTs have emerged as critical regulators of immune responses. They modulate immune checkpoint molecules, including programmed cell death protein 1 (PD-1), through arginine methylation. Drug resistance is a significant challenge in cancer treatment, and PRMTs have been implicated in this phenomenon. PRMTs can contribute to drug resistance through multiple mechanisms, including the epigenetic regulation of drug efflux pumps, altered DNA damage repair, and modulation of cell survival pathways. In conclusion, PRMTs play critical roles in cancer pathogenesis, immunotherapy, and drug resistance. In this overview, we have endeavored to illuminate the mechanistic intricacies of PRMT-mediated processes. Shedding light on these aspects will offer valuable insights into the fundamental biology of cancer and establish PRMTs as promising therapeutic targets.

PRMT7 can prevent neurovascular uncoupling, blood-brain barrier permeability, and mitochondrial dysfunction in repetitive and mild traumatic brain injury. Exp Neurol 2023; 366:114445. [PMID: 37196697 PMCID: PMC10960645 DOI: 10.1016/j.expneurol.2023.114445] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Revised: 05/03/2023] [Accepted: 05/12/2023] [Indexed: 05/19/2023]
Abstract
Mild traumatic brain injury (TBI) comprises the largest percentage of TBI-related injuries, with pathophysiological and functional deficits that persist in a subset of TBI patients. In our three-hit paradigm of repetitive and mild traumatic brain injury (rmTBI), we observed neurovascular uncoupling via decreased red blood cell velocity, microvessel diameter, and leukocyte rolling velocity 3 days post-rmTBI via intra-vital two-photon laser scanning microscopy. Furthermore, our data suggest increased blood-brain barrier (BBB) permeability (leakage), with corresponding decrease in junctional protein expression post-rmTBI. Mitochondrial oxygen consumption rates (measured via Seahorse XFe24) were also altered 3 days post-rmTBI, along with disrupted mitochondrial dynamics of fission and fusion. Overall, these pathophysiological findings correlated with decreased protein arginine methyltransferase 7 (PRMT7) protein levels and activity post-rmTBI. Here, we increased PRMT7 levels in vivo to assess the role of the neurovasculature and mitochondria post-rmTBI. In vivo overexpression of PRMT7 using a neuronal specific AAV vector led to restoration of neurovascular coupling, prevented BBB leakage, and promoted mitochondrial respiration, altogether to suggest a protective and functional role of PRMT7 in rmTBI.

Marzochi LL, Cuzziol CI, Nascimento Filho CHVD, Dos Santos JA, Castanhole-Nunes MMU, Pavarino ÉC, Guerra ENS, Goloni-Bertollo EM. Use of histone methyltransferase inhibitors in cancer treatment: A systematic review. Eur J Pharmacol 2023; 944:175590. [PMID: 36775112 DOI: 10.1016/j.ejphar.2023.175590] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 02/02/2023] [Accepted: 02/09/2023] [Indexed: 02/12/2023]
Abstract
Histone modifications are an epigenetic mechanism, and the dysregulation of these proteins is known to be associated with the initiation and progression of cancer. In the search for the development of new and more effective drugs, histone modifications were identified as possible therapeutic targets. Histone methyltransferase (HMT) inhibitors correspond to the third generation of epigenetic drugs capable of writing or deleting epigenetic information. This systematic review summarized the development and prospect for the use of different HMT inhibitors in cancer therapy. An electronic search was applied across CENTRAL, Clinical Trials, Embase, LILACS, LIVIVO, Open Gray, PubMed, Scopus, and Web of Science. Based on the title and abstracts, two authors independently selected eligible studies. After the complete reading of the articles, based on the eligibility criteria, 11 studies were included in the review. Different inhibitors of HMT have been explored in multiple clinical studies, and have shown considerable anti-tumor effects. However, few phase 2 studies have been completed and/or have available results. The most advanced clinical trials mainly include tazemetostat, an Enhancer of zeste homolog 2 (EZH2) inhibitor approved for follicular lymphoma (FL). The use of HMT inhibitors has presented, so far, concise results in the treatment of hematological cancers, moreover, the adverse effects presented after the use of these medicines (alone or in combination) did not show a high level of risk for the patient. These findings, in addition to ongoing clinical studies, can represent a promising future regarding the use of HMT inhibitors in treating different types of cancer.
