Summary: In this study, the role of plectin in the migration and epithelial mesenchymal transition (EMT) of hepatocellular carcinoma (HCC) cells was investigated. Plectin expression was found to be significantly increased in HCC tissue and cells. Downregulation of plectin inhibited HCC cell migration and EMT, which was mediated by the suppression of ERK1/2 signaling. Activation of ERK1/2 reversed the inhibitory effects of plectin downregulation.

Summary: In this study, a novel fluorene derivative, 9-methanesulfonylmethylene-2, 3-dimethoxy-9 H-fluorene (MSDF), was found to have anticancer potential in human hepatocellular carcinoma (HCC) cells. MSDF induced apoptosis through both receptor-mediated extrinsic and mitochondrial-mediated intrinsic pathways. It also caused anoikis and cell death by disrupting cell-ECM contact. MSDF suppressed the MAPK/ERK and PI3K/Akt signaling pathways and downregulated the expression of immune checkpoint proteins.

Summary: Platycodon grandiflorum is a medicinal plant commonly used in East Asia, and its triterpene saponins have shown anti-tumor effects. In this study, the inhibitory effect of polygalacin D (PGD) on hepatocellular carcinoma cells was investigated. PGD was found to induce apoptosis and autophagy in these cells through the mitochondrial apoptosis and mitophagy pathways. In addition, in vivo experiments confirmed the anti-tumor activity of PGD. These findings suggest that PGD can be developed as a novel anti-tumor agent by targeting the apoptosis and autophagy pathways.

Summary: The high expression of RSPH14 in hepatocellular carcinoma (HCC) is associated with poor prognosis. Knockdown of RSPH14 can inhibit cell proliferation, migration, and invasion, and promote apoptosis of HCC cells by inhibiting the expression of RelA. RSPH14 may be a potential new treatment target for HCC.

Summary: The study found that MTA2 regulates HCC progression through the MTA2-FAK-MMP7 pathway. PTK7, as a downstream factor of MTA2, affects the migration and invasion abilities of HCC cells by regulating MMP7 expression. The expression level of PTK7 is correlated with tumor stage, grade, and overall survival in HCC patients, and may have diagnostic value for HCC patients.

Summary: In this study, we found that ASPM was significantly upregulated in LIHC and its high expression was associated with poor prognosis. Knockdown of ASPM suppressed LIHC cell proliferation, migration, and invasion, while overexpression had the opposite effect. Mechanistically, we revealed that METTL3-mediated N6-methyladenosine modification of ASPM mRNA promoted its expression in LIHC. Silencing METTL3 also inhibited LIHC cell proliferation, migration, and invasion, but this effect could be rescued by overexpression of ASPM. These findings suggest that the METTL3/ASPM axis may be a promising therapeutic target for LIHC.

Summary: Clinical analysis indicates that SQSTM1/p62 is highly expressed in HCC and affects patient prognosis. Knocking out SQSTM1/p62 using the CRISPR/Cas9 system impairs HCC migration and invasion, upregulates Keap1, and promotes the inhibitory effect of Keap1 on Nrf2. Inactivation of Nrf2 inhibits MMP expression, attenuating HCC migration and invasion. SQSTM1/p62 knockout also inhibits migration and invasion in a mouse model of lung metastasis. Cisplatin inhibits SQSTM1/p62 expression and slows down HCC migration and invasion, while the inflammatory microenvironment accelerates HCC migration and invasion. This study suggests that SQSTM1/p62 knockout inhibits HCC migration and invasion through the Keap1/Nrf2/MMP2 signaling pathway, highlighting it as a potential drug target.

Summary: In studying the mechanisms controlling front-rear polarity in migrating cells using zebrafish primordial germ cells as an in vivo model, it was found that the accumulation and flow of actin plays a key role. Following cell division, the accumulation of Ezrin at the cleavage plane is the first sign for cell polarity. The antagonistic interactions between the cell front and back determine the polarization of the cell.

Summary: There is increasing evidence showing the crucial role of the immune microenvironment, particularly the polarization state and function of macrophages, in the development of hepatocellular carcinoma. Tumor-derived exosomes in hepatocellular carcinoma act as information carriers and regulate the physiological state of cells in the microenvironment, thus controlling cancer progression. This review focuses on the role of exosome content in disease outcomes at different stages of hepatitis B virus/hepatitis C virus-induced hepatocellular carcinoma, and explores the mechanism by which macrophages contribute to hepatocellular carcinoma formation and the regulation of macrophage functions by the heterogeneity of exosome loading. The application prospects of exosome-based targeted drug delivery in immunotherapy research on hepatocellular carcinoma are also summarized.

Summary: Calycosin exhibited anti-proliferation effects on HCC cells and had less cytotoxicity in normal cells. It induced apoptosis by regulating various signaling pathways and caused cell cycle arrest in the G0/G1 phase. Additionally, calycosin reduced the expression of certain proteins and induced cellular events through ROS-mediated pathways.

Summary: YEATS family proteins recognize acylated histones and regulate chromatin structure, gene transcription, and stress signaling. In this study, researchers identified inhibitors for the AF9 YEATS domain and designed new inhibitors based on complex structures and affinity assays. These inhibitors showed antiproliferation activities in AF9-sensitive cancer cells. This work provides a basis for further optimization of AF9 YEATS inhibitors.

Summary: This study presents a detailed computational model of the physical interactions within the human CENPHIKM complex, validating the structural similarity with fungal and yeast orthologs. The binding mode of CENP-M to the C-terminus of CENP-I in humans is also confirmed based on existing experimental evidence. Overall, the results support the hypothesis that the human CENP-HIK complex shares similar architecture with its orthologs and highlight the importance of understanding kinetochore functionality and assembly mechanisms.
