Summary: This study revealed a novel circular RNA (circPTEN1) generated from the PTEN gene, which is downregulated in colorectal cancer and associated with poor survival. Low expression of circPTEN1 promotes metastasis and invasion, while overexpression shows opposite effects. Mechanistically, circPTEN1 binds to Smad4 and disrupts its interaction with Smad2/3, inhibiting the formation and translocation of Smad complexes. Additionally, eIF4A3 suppresses the cyclization of circPTEN1.

Summary: Analysis of TCGA data revealed a high activation of the TGF-beta pathway in GBMs compared to oligodendroglial tumors. Stimulation of GBM cell lines with TGF-beta 1 enhanced MT formation and communication via calcium signaling, while inhibition of the TGF-beta pathway significantly reduced MT formation and invasion. Downstream of TGF-beta, thrombospondin 1 (TSP1) was identified as a potential mediator of MT formation in GBM, which was upregulated upon TGF-beta stimulation and inhibited MT formation when knocked down in vitro and in vivo.

Summary: CCN2 plays a role in both fibrotic responses and growth factor-induced oxidative and proinflammatory responses. Its coexistence with TGF-β is necessary for persistent fibrotic response, but the mechanisms involved are not fully understood. CCN2 increases T beta RII expression in VSMCs and maintains TGF-β pathway activation through an EGFR-SMAD dependent manner.

Summary: Expansion of interstitial cells in adult kidney is a hallmark of chronic disease, while their proliferation during fetal development is necessary for organ formation. Inactivation of TGF beta/Smad response in mouse interstitial cell lineage leads to overproliferation of interstitial cells regionally in the kidney medulla. Smad4 loss primarily reduces TGF beta signaling in the interstitium, while increasing Wnt/beta-catenin signaling.

Summary: Cardiac fibrosis is a remodeling process characterized by abnormal metabolism of the extracellular matrix and excessive accumulation of collagen fibers. Transforming growth factor-beta 1 (TGF-beta 1) plays a crucial role in this process. Studies have shown that interfering with TGF-beta 1 and its signaling pathways using latency-associated peptide (LAP) can attenuate cardiac fibrosis. In this study, recombinant LAP and truncated LAP were found to inhibit activation, inflammation, and fibrosis in isoproterenol-induced cardiac fibroblasts, and also improved cardiac function and alleviated myocardial injury, inflammation, and fibrosis in mice.

Summary: This study found that LGR4 expression was significantly upregulated in multiple myeloma (MM) tissues and cells. Knockdown of LGR4 inhibited MM cell proliferation, promoted apoptosis and cell cycle arrest in G1, while overexpression showed the opposite effect. Mechanistic studies revealed that LGR4 could interact with TGF-beta 1 and activate the TGF-beta 1/Smad signaling pathway, promoting MM progression. LGR4 may be a potential new target for MM diagnosis and treatment.

Summary: The study aimed to block TGF-beta-induced SMAD1/5/9 signaling in primary human OA chondrocytes while maintaining functional SMAD2/3 signaling. The results demonstrated that using a low dose of SB-505124 inhibited SMAD1/5/9 phosphorylation and the expression of ID1 and ID3, while maintaining SMAD2/3 phosphorylation and the induction of JUNB and SERPINE1. In addition, TGF-beta regulated hypertrophic and dedifferentiation markers in OA chondrocytes, and blocking only the SMAD1/5/9 pathway showed stronger inhibition on TGF-beta-induced RUNX2 compared to blocking both SMAD pathways.

Summary: Research on TGF-beta/Smad signaling has shown its significance in neurogenesis and its potential impact on neuropsychiatric disorders. The relationship between TGF-beta/Smad signaling and neurogenesis in response to stressors suggests a role in stress response regulation and behavioral outcomes of mood disorders. Modifications to these signaling pathways have been found to have diverse effects on neurogenesis, highlighting the complexity of the interactions involved.

Summary: In this study, a transcriptional signature of PTEN loss in prostate cancer was identified, showing activation of immune systems and cell-cycle genes. The study also discovered potential novel lncRNAs associated with PTEN loss and prostate cancer progression, expanding the understanding of the molecular landscape in PCa. The findings suggest that PTEN loss in prostate cancer leads to increased immune system activation, contrary to observations in other cancers, which could have implications for the development of biomarkers and therapy choices.

Summary: Cardiac fibrosis is a serious global public health problem associated with the progression of cardiovascular diseases. The TGF-beta/Smad signaling pathway plays a key role in cardiac fibrosis, and targeted inhibition of this pathway may be a therapeutic approach. Traditional Chinese Medicine (TCM) has also been found to modulate multiple targets and signaling pathways, including TGF-beta/Smad, in the treatment of cardiac fibrosis. This article summarizes the roles of TGF-beta/Smad signaling pathways and discusses recent research on ncRNAs and TCM as potential treatments for cardiac fibrosis.

Summary: Patients with primary biliary cholangitis (PBC) are at higher risk for developing hepatocellular carcinoma (HCC), especially in the presence of comorbidities like excessive alcohol consumption. This study found that the balance of Smad signals may serve as a biomarker to predict the likelihood of HCC occurrence in PBC patients. Shifting favorably Smad phospho-isoforms through therapies could potentially reduce the risk of PBC-related HCC development.

Summary: TGF-beta signaling through Smad2/3 regulates macrophage responses in myocardial infarction. Smad3 plays a crucial role in mediating the anti-inflammatory and phagocytic effects of TGF-beta, while the activation of Smad2 does not affect these processes. Smad3, but not Smad2, is the main mediator of transcriptional effects of TGF-beta on macrophages.

Summary: This study identifies a functional KDM1A-FKBP8-BCL2 axis in hepatocellular carcinoma (HCC), showing that KDM1A can demethylate FKBP8 to enhance the stability of BCL2, promoting HCC cell growth. The cytoplasmic localization of KDM1A is regulated by acetylation at lysine-117 by KAT8. In addition, the study reveals that KDM1A and BCL2 protein levels increase during acquired sorafenib resistance and inhibiting KDM1A can antagonize this resistance.

Summary: RfxCas13d is an RNA-guided RNA endonuclease that can knockdown gene expression with high specificity. In this study, we investigated the mechanism of its inducible knockdown and designed an all-in-one Cas13d lentivirus vector that allows efficient and inducible knockdown depending on the dosage of doxycycline. Furthermore, we found that Cas13d has a short half-life in mammalian cells, allowing prompt restoration of knockdown after doxycycline withdrawal. This research has significant implications for future applications.

Summary: Prevalent dysregulation of epigenetic modifications plays a pivotal role in cancer. O-GlcNAcylation, a protein modification that affects physiology and pathophysiology, is closely related to epigenetic modifications, and oncogenic signals regulate epigenetic abnormalities in cancer by modulating O-GlcNAcylation dysregulation.
