These cells arise from various lineages and exhibit complex dynamics. However, effectively targeting DTP cells remains challenging. We used single-cell RNA sequencing (scRNA-Seq) data and machine learning (ML) models to identify DTP cells in patient-derived organoids (PDOs) and computationally screened candidate drugs targeting these cells in familial adenomatous polyposis (FAP), associated with a high risk of colorectal cancer. Three PDOs (benign and malignant tumor organoids and a normal organoid) were evaluated using scRNA-Seq. ML models constructed based on public scRNA-Seq data classified DTP versus non-DTP cells. Candidate drugs for DTP cells in a malignant tumor organoid were identified from public drug sensitivity data. From FAP scRNA-Seq data, a specific TC1 cell cluster in tumor organoids was identified. The ML model identified up to 36 % of TC1 cells as DTP cells, a higher proportion than those for other clusters. A viability assay using a malignant tumor organoid demonstrated that YM-155 and THZ2 exert synergistic effects with trametinib. The constructed ML model is effective for DTP cell identification based on scRNA-Seq data for FAP and provides candidate treatments. This approach may improve DTP cell targeting in the treatment of colorectal and other cancers.","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.

Previously, we reported that Dox induces phosphorylation of lamin A/C (pS22 lamin A/C), increased nuclear size, damage to the nuclear membrane, and cell death. However, the activation of signalling pathway during this event remains elusive, and it is unclear whether increased phospho-lamin A/C activates the cell death pathway in heart. Here, we demonstrated that Dox-induced lamin A/C phosphorylation causes apoptotic cell death. Increased levels of reactive oxygen species (ROS), DNA methylation and apoptosis markers (Bax, Bid, caspase 3 and caspase 9) were observed in Dox-exposed H9c2 cells. Nuclear membrane damage due to increased pS22 lamin A/C causes increased DNMT1 and DNA methylation followed by reduced expression of GATA-4 and Bcl-xL in Dox-treated H9c2 cells and rat hearts. Further, increased mRNA expression of DNMT1 and reduced expression of GATA-4 and Bcl-xL was observed in H9c2 cells after knocking down of lamin A/C expression. Previously, we reported that N-acetylcysteine improves lamin A/C levels and maintain nuclear membrane integrity. Similarly, in this study Astaxanthin (Ast), a membrane-specific antioxidant, reduces the expression of DNMT1 and phospho-lamin A/C levels; increases mRNA expression of GATA-4 and Bcl-xL; reduces ROS levels and DNA leakage in Dox-treated H9c2 cells and rat hearts. Ast also improves the cardiac structure and function in Dox-treated rats. In conclusion, Dox exposure in cardiomyoblasts and hearts causes cell death by increasing the pS22 lamin A/C, DNA methylation and reducing the expression GATA-4 and Bcl-xL. This study provides a novel pathway for Dox-induced cardiotoxicity and a possible therapeutic approach to reduce it.","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.

Mitochondrial sirtuins are NAD+-dependent deacetylases that play a central role in cellular metabolism and function as epigenetic regulators by performing post-translational modification of cellular proteins. Several studies have identified the role of mitochondrial sirtuins in age-related pathologies and the rewiring of cancer metabolism. Mitochondrial sirtuins regulate cellular functions by contributing to post-translational modifications, including deacetylation, ADP-ribosylation, demalonylation, and desuccinylation of diverse cellular proteins to maintain cellular homeostasis. Here, we review and discuss the structure and function of the mitochondrial sirtuins and their role as metabolic regulators in breast cancer. Altered breast cancer metabolism may promote tumor progression and has been an essential target for therapy. Further, we discuss the potential role of targeting mitochondrial sirtuin and its impact on breast cancer progression using sirtuin inhibitors and activators as anticancer agents.","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.

Liver fibrosis is the result of sustained inflammation and injury to the liver due to a variety of factors, triggering excessive deposition of extracellular matrix and fibrous scar formation, which in turn leads to loss of liver function and a variety of related complications. Endoplasmic reticulum stress is one of the characteristics of chronic liver disease and is closely related to the pathological process of chronic liver disease, including alcohol-related liver disease, viral hepatitis, and liver fibrosis. The unfolded protein response is one of the important response mechanisms to endoplasmic reticulum stress. It is associated with several pathological aspects of liver fibrosis and the maintenance of endoplasmic reticulum homeostasis. Interventions targeting endoplasmic reticulum stress for the treatment of liver fibrosis have potential research and application value. An in-depth understanding of the biological basis of endoplasmic reticulum stress is also needed in the treatment of liver fibrosis, as well as the development of more effective drugs and interventions to accurately regulate the endoplasmic reticulum signaling network, to achieve the restoration and maintenance of endoplasmic reticulum homeostasis at the cellular and organ levels, and to further promote the reversal of the pathological process of liver fibrosis.","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.

Drug repurposing, particularly through network medicine approaches, offers a promising avenue for cancer treatment by analyzing how drugs influence cellular networks on a systemic scale. The advent of large-scale proteomics data provides new opportunities to elucidate regulatory mechanisms specific to cancer subtypes. Herein, we present NetSDR, a Network-based Subtype-specific Drug Repurposing framework for prioritizing repurposed drugs specific to certain cancer subtypes, guided by subtype-specific proteomic signatures and network perturbations. First, by integrating cancer subtype information into a network-based method, we developed a pipeline to recognize subtype-specific functional modules. Next, we conducted drug response analysis for each module to identify the \"therapeutic module\" and then used deep learning to construct weighted drug response network for the particular subtype. Finally, we employed a perturbation response scanning-based drug repurposing method, which incorporates dynamic information, to facilitate the prioritization of candidate drugs. Applying the framework to gastric cancer, we attested the significance of the extracellular matrix module in treatment strategies and discovered a promising potential drug target, LAMB2, as well as a series of possible repurposed drugs. This study demonstrates a systems biology framework for precise drug repurposing in cancer and other complex diseases.","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.

However, the specific regulatory mechanisms remain unclear. We identified pyroptosis-related differentially expressed genes (DEGs) based on the GSE4183 and GSE44861 datasets as well as EVenn database. Expression levels of key genes were detected by qRT-PCR. IKZF1 was overexpressed in colon cancer cells and tumor-bearing mice, and its functions were assessed by various cell biology assays in vitro and in vivo. To investigate the interactions between IKZF1 and macrophages, a co-culture system was constructed. The activator RO8191 or inhibitor ruxolitinib of the JAK/STAT pathway was employed to confirm whether IKZF1 inhibited colon cancer development by regulating JAK2/STAT5 pathway. Pyroptosis-related hub genes RBBP7, HSP90AB1, and RBBP4 were highly expressed, while IKZF1, NLRP1, and PYCARD were lowly expressed. These hub genes had good performance in distinguishing colon cancer from controls. Furthermore, overexpression of IKZF1 inhibited tumor growth and promoted pyroptosis. Overexpression of IKZF1 suppressed cell proliferation, metastasis, and inactivated JAK2/STAT5 signaling pathway in colon cancer cells. Furthermore, upregulation of IKZF1 promoted M1 macrophage polarization while inhibiting M2 macrophage polarization in vivo and in vitro by inhibiting the JAK2/STAT5 signaling pathway.

It was an independent predictor of progression-free survival following treatment and the overall survival of ccRCC patients. ALB overexpression exhibited the reverse effects of ALB knockdown, which increased cell proliferation, migration, and invasion while inhibiting cell death. Similarly, ALB overexpression inhibited the growth of ccRCC tumors in vivo. Consistent with functional enrichment analysis, ALB overexpression activates the endoplasmic reticulum stress (ERS) in vitro and vivo. The Mendelian randomization showed ALB was associated with the risk of ccRCC. Additionally, ALB was causally associated with γδT cells infiltrates in ccRCC.Conclusion: ALB plays an important effect in ccRCC via activation of the ERS and regulating immune microenvironment.","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.

Piplartine (PLG), an alkaloid extracted from Piper longum within the Piperaceae family, has exhibited diverse pharmacological activities, including anti-inflammatory, anti-atherosclerotic, and anti-tumor effects. Herein, we investigated whether the PLG could reverse SI-AKI and explore its possible anti-inflammatory mechanisms. We constructed an SI-AKI model using cecal ligation and puncture (CLP) and systematically evaluated the protective effect of PLG administered by gavage in the SI-AKI mice. Subsequently, we performed proteomic sequencing of the kidney and integrated data from the GeneCards and SwissTargetPrediction databases to identify potential targets and mechanisms. Immunofluorescence and western blotting were used to examine the expression of relevant targets and pathways in vivo and in vitro. The influence of PLG on the predicted target and pathway was verified using an agonist of the target protein and a series of biochemical experiments. PLG exhibited significant efficacy against pathological damage, neutrophil and macrophage infiltration, and macrophage pyroptosis in kidneys at 30 mg/kg. An integrated analysis of proteomic data identified the translocator protein (TSPO) as a potential target for the renoprotective effects of PLG. Moreover, a TSPO agonist (RO5-4864) prominently reversed the protective effect of PLG in SI-AKI mice, as manifested by a deterioration in renal function, histopathological lesions and macrophage pyroptosis in the kidneys. Our results suggest that PLG may ameliorate SI-AKI, potentially through partial inhibition of the TSPO-macrophage pyroptosis pathway.","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.

Treatment of OP is characterized by a lifelong nature, causing extreme financial and psychological burdens to patients. Hormonal abnormalities, cellular autophagy, Ferroptosis, and oxidative stress are all part of the intricate and varied pathophysiology of OP. Recent research has revealed that mitochondrial dysfunction is a significant factor in the onset and progression of OP. By regulating bone marrow mesenchymal stem cell differentiation through various signaling pathways and cytokines, abnormal mitochondrial energy metabolism brought on by oxidative stress processes impacts osteoblast and osteoclast proliferation and differentiation, causing an imbalance in bone metabolism that ultimately results in OP. Therefore, one possible method to prevent and manage OP may be to use mitochondria as a carrier to trigger osteogenic differentiation of bone marrow mesenchymal stem cells from mitochondrial energy consumption, oxidative stress, autophagy, and osteoclast death. In order to offer some theoretical references and therapeutic approaches for the clinical prevention and treatment of OP, we will examine the pathophysiology of OP from mitochondrial dysfunction in this work.","PeriodicalId":93896,"journal":{"name":"Biochimica et biophysica acta.
