Abstract
ABSTRACT In humans, the liver is a central metabolic organ with a complex and unique histological microenvironment. Hepatocellular carcinoma (HCC), which is a highly aggressive disease with a poor prognosis, accounts for most cases of primary liver cancer. As an emerging hallmark of cancers, metabolic reprogramming acts as a runaway mechanism that disrupts homeostasis of the affected organs, including the liver. Specifically, rewiring of the liver metabolic microenvironment, including lipid metabolism, is driven by HCC cells, propelling the phenotypes of HCC cells, including dissemination, invasion, and even metastasis in return. The resulting formation of this vicious loop facilitates various malignant behaviors of HCC further. However, few articles have comprehensively summarized lipid reprogramming in HCC metastasis. Here, we have reviewed the general situation of the liver microenvironment and the physiological lipid metabolism in the liver, and highlighted the effects of different aspects of lipid metabolism on HCC metastasis to explore the underlying mechanisms. In addition, we have recapitulated promising therapeutic strategies targeting lipid metabolism and the effects of lipid metabolic reprogramming on the efficacy of HCC systematical therapy, aiming to offer new perspectives for targeted therapy.

Peroxisome proliferator-activated receptor gamma coactivator-1 (PGC-1) family in physiological and pathophysiological process and diseases. Signal Transduct Target Ther 2024; 9:50. [PMID: 38424050 PMCID: PMC10904817 DOI: 10.1038/s41392-024-01756-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 01/13/2024] [Accepted: 01/23/2024] [Indexed: 03/02/2024] Open
Abstract
Peroxisome proliferator-activated receptor gamma coactivator-1 (PGC-1) family (PGC-1s), consisting of three members encompassing PGC-1α, PGC-1β, and PGC-1-related coactivator (PRC), was discovered more than a quarter-century ago. PGC-1s are essential coordinators of many vital cellular events, including mitochondrial functions, oxidative stress, endoplasmic reticulum homeostasis, and inflammation. Accumulating evidence has shown that PGC-1s are implicated in many diseases, such as cancers, cardiac diseases and cardiovascular diseases, neurological disorders, kidney diseases, motor system diseases, and metabolic disorders. Examining the upstream modulators and co-activated partners of PGC-1s and identifying critical biological events modulated by downstream effectors of PGC-1s contribute to the presentation of the elaborate network of PGC-1s. Furthermore, discussing the correlation between PGC-1s and diseases as well as summarizing the therapy targeting PGC-1s helps make individualized and precise intervention methods. In this review, we summarize basic knowledge regarding the PGC-1s family as well as the molecular regulatory network, discuss the physio-pathological roles of PGC-1s in human diseases, review the application of PGC-1s, including the diagnostic and prognostic value of PGC-1s and several therapies in pre-clinical studies, and suggest several directions for future investigations. This review presents the immense potential of targeting PGC-1s in the treatment of diseases and hopefully facilitates the promotion of PGC-1s as new therapeutic targets.

Mitochondrial ribosomal protein L12 potentiates hepatocellular carcinoma by regulating mitochondrial biogenesis and metabolic reprogramming. Metabolism 2024; 152:155761. [PMID: 38104924 DOI: 10.1016/j.metabol.2023.155761] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 12/09/2023] [Accepted: 12/11/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Mitochondrial dysfunction and metabolic reprogramming are key features of hepatocellular carcinoma (HCC). Despite its significance, the precise underlying mechanism behind these processes has not been fully elucidated. The latest investigations, along with our previous discoveries, have substantiated the significant role of mitochondrial ribosomal protein L12 (MRPL12), a newly identified gene involved in mitochondrial transcription regulation, in the modulation of mitochondrial metabolism. Nevertheless, the role of MRPL12 in tumorigenesis has yet to be investigated. METHODS The expression of MRPL12 in HCC was assessed using an online database. Western blot, quantitative real-time polymerase chain reaction (qRT-PCR), and immunohistochemistry (IHC) were employed to determine the expression of MRPL12 in HCC tissues, patient-derived organoid (PDO), and cell lines. The correlation between MRPL12 expression and clinicopathological features, as well as prognosis, was examined using tissue microarray analysis. An in vivo subcutaneous tumor xenograft model, gene knockdown or overexpression assay, chromatin immunoprecipitation (ChIP) assay, Seahorse XF96 assay, and cell function assay were employed to investigate the biological function and potential molecular mechanism of MRPL12 in HCC. RESULTS A significant upregulation of MRPL12 was observed in HCC cells, PDO and patient tissues, which correlated with advanced tumor stage, higher grade and poor prognosis. MRPL12 overexpression promoted cell proliferation, migration, and invasion in vitro, as well as tumorigenicity in vivo, whereas MRPL12 knockdown showed the opposite effect. MRPL12 knockdown also inhibited the capacity of organoids proliferation capacity. Furthermore, MRPL12 was found to be crucial for maintaining mitochondrial homeostasis. Both gain and loss-of-function experiments targeting MRPL12 in HCC cells altered oxidative phosphorylation (OXPHOS) and mitochondrial DNA content. Notably, suppression of OXPHOS effectively mitigates the tumor-promoting effect attributed to MRPL12 overexpression, implying the involvement of MRPL12 in HCC through the modulation of mitochondrial metabolism. Besides, Yin Yang 1 (YY1) was identified as a transcription factor responsible for regulating MRPL12, while the PI3K/mTOR pathway was found to act as an upstream regulator of YY1. MRPL12 knockdown attenuated the YY1 overexpression or PI3K/mTOR activation-induced malignant phenotype in HCC cells. CONCLUSION Our findings provide compelling evidence that MRPL12 is implicated in driving the malignant phenotype of HCC via regulating mitochondrial metabolism. Moreover, the aberrant expression of MRPL12 in HCC is mediated by the upstream PI3K/mTOR/YY1 pathway. These results highlight the potential of targeting MRPL12 as a promising therapeutic strategy for the treatment of HCC.
