Abstract
BACKGROUND AMP-activated protein kinase (AMPK) plays a precise role as a master regulator of cellular energy homeostasis. AMPK is activated in response to the signalling cues that exhaust cellular ATP levels such as hypoxia, ischaemia, glucose depletion and heat shock. As a central regulator of both lipid and glucose metabolism, AMPK is considered to be a potential therapeutic target for the treatment of various diseases, including eye disorders. OBJECTIVE To review all the shreds of evidence concerning the role of the AMPK signalling pathway in the pathogenesis of ocular diseases. METHOD Scientific data search and review of available information evaluating the influence of AMPK signalling on ocular diseases. RESULTS Review highlights the significance of AMPK signalling in the aetiopathogenesis of ocular diseases, including cataract, glaucoma, diabetic retinopathy, retinoblastoma, age-related macular degeneration, corneal diseases, etc. The review also provides the information on the AMPK-associated pathways with reference to ocular disease, which includes mitochondrial biogenesis, autophagy and regulation of inflammatory response. CONCLUSION The study concludes the role of AMPK in ocular diseases. There is growing interest in the therapeutic utilization of the AMPK pathway for ocular disease treatment. Furthermore, inhibition of AMPK signalling might represent more pertinent strategy than AMPK activation for ocular disease treatment. Such information will guide the development of more effective AMPK modulators for ocular diseases.[Formula: see text].

[PMID: 34082186 DOI: 10.1016/j.cancergen.2021.05.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Revised: 04/21/2021] [Accepted: 05/10/2021] [Indexed: 11/17/2022]
Abstract
PURPOSE This study was designed to identify mitochondrial (mt) DNA variations in primary and metastatic uveal melanoma (UM) cell lines and their relation with cell metabolism to gain insight into metastatic progression. METHOD The entire mtDNA genomes were sequenced using Sanger sequencing from two primary UM cell lines (92.1 and MEL270) and two cell lines (OMM2.3 and OMM2.5) derived from liver metastases of the MEL270 patient. The mtDNA copy numbers determined by the ratio of nDNA versus mtDNA. qRT-PCR was used to evaluate expression levels of mitochondrial biogenesis genes. RESULTS Sequencing showed that cell line MEL270 and metastases-derived OMM2.3 and OMM2.5 cell lines had homoplasmic single nucleotide polymorphisms (SNPs) representing J1c7a haplogroup, whereas 92.1 cells had mtDNA H31a haplogroup. mtDNA copy numbers were significantly higher in primary cell lines. The metastatic UM cells showed down-regulation of POLG, TFAM, NRF-1 and SIRT1 compared to their primary MEL270 cells. PGC-1α was downregulated in 92.1 and upregulated in MEL270, OMM2.3 and OMM2.5. CONCLUSIONS Our finding suggests that within metastatic cells, the heteroplasmic SNPs, copy numbers and mitochondrial biogenesis genes are modulated differentially compared to their primary UM cells. Therefore, investigating pathogenic mtDNA variants associated with cancer metabolic susceptibility may provide future therapeutic strategies in metastatic UM.

The deacetylation-phosphorylation regulation of SIRT2-SMC1A axis as a mechanism of antimitotic catastrophe in early tumorigenesis. SCIENCE ADVANCES 2021; 7:7/9/eabe5518.

Abstract
Improper distribution of chromosomes during mitosis can contribute to malignant transformation. Higher eukaryotes have evolved a mitotic catastrophe mechanism for eliminating mitosis-incompetent cells; however, the signaling cascade and its epigenetic regulation are poorly understood. Our analyses of human cancerous tissue revealed that the NAD-dependent deacetylase SIRT2 is up-regulated in early-stage carcinomas of various organs. Mass spectrometry analysis revealed that SIRT2 interacts with and deacetylates the structural maintenance of chromosomes protein 1 (SMC1A), which then promotes SMC1A phosphorylation to properly drive mitosis. We have further demonstrated that inhibition of SIRT2 activity or continuously increasing SMC1A-K579 acetylation causes abnormal chromosome segregation, which, in turn, induces mitotic catastrophe in cancer cells and enhances their vulnerability to chemotherapeutic agents. These findings suggest that regulation of the SIRT2-SMC1A axis through deacetylation-phosphorylation permits escape from mitotic catastrophe, thus allowing early precursor lesions to overcome oncogenic stress.

Abstract
Purpose To determine the expression of histone deacetylase enzymes in uveal melanoma tumour cells. Procedures This is an observational immunohistochemical study of 16 formalin-fixed, paraffin-embedded eyes enucleated for uveal melanoma between January 2001 and March 2002. Haematoxylin and eosin paraffin sections were reviewed for histopathological parameters according to the American Joint Committee on Cancer 7th edition. Sections were then immunohistochemically stained for histone deacetylases 1, 2, 3, 4 and 6 and sirtuin 2 using an automated Leica Bond II platform and Fast Red chromogen, then digitally scanned using Aperio software before assessment of staining. Results Nuclear expression of histone deacetylases 1, 2, 3, 4 and 6 and of sirtuin 2 was confirmed in uveal melanoma tumour cells. In addition, the tumour cells showed cytoplasmic expression of histone deacetylases 4 and 6 and sirtuin 2. Nuclear and cytoplasmic immunostaining was also seen in intraocular tissues uninvolved by the tumour. Conclusion Uveal melanoma tumour cells express histone deacetylases 1, 2, 3, 4 and 6 and sirtuin 2, confirming potential tissue targets for histone deacetylase inhibitors.
