Proteomic analysis of bone marrow cells from wild-type and Dcaf8 knockout mice

ABSTRACT: To explore the mechanisms by which DCAF8 deficiency induces functional defects in hematopoietic stem cells with an aging-like phenotype, and given DCAF8’s role as a substrate receptor in the E3 ubiquitin ligase complex, we conducted ubiquitin proteomic analysis on bone marrow cells from wild-type and Dcaf8 knockout mice. This analysis aimed to identify ubiquitinated proteins and assess changes in ubiquitination, providing insights into potential substrates of DCAF8 in murine hematopoietic cells.

<h4>Abstract</h4>Hematopoietic stem cells (HSCs) are responsible for sustaining the hematopoietic system throughout life, and their functional decline contributes to hematological disorders and organismal aging. Understanding the molecular mechanisms that govern HSC function is critical for developing interventions for treating and preventing aging-related diseases. Here, we show that DCAF8, a substrate recognition component of Cullin-RING E3 ubiquitin ligases, is highly expressed in HSCs and un ...[more]

Mapping of bone marrow sample proteome of Pinch1/2 knockout mice

Project description:Mesenchymal stromal cells (MSCs) are used to treat infectious and immune diseases and disorders; however, its mechanism(s) remain incompletely defined. Here we find that MSCs lacking Pinch1/2 proteins display dramatically reduced ability to suppress lipopolysaccharide (LPS)-induced acute lung injury and dextran sulfate sodium (DSS)-induced inflammatory bowel disease in mice. Mice with Pinch loss in MSCs have severe defects in both immune and hematopoietic functions, resulting in premature death, which can be restored by intravenous injection of wild-type but not Pinch-deficient MSCs.

Comprehensive proteomics characterization identify biomarkers of liver cancer subtypes

Project description:Recurrence and metastasis remain the major obstacles to prognosis of hepatocellular carcinoma (HCC), but the relationship between proteomics and poor prognosis need to be studied more systematically. In this study, we performed the proteomics data collected from 85 HCC tumors and 18 adjacent normal tissues (ANTs) to establish the proteomics profiles of HCC and reveal the correlation between poteomics and ubiquitomics features of tumor tissues in HCC. Our data bring new insights on multi-omics data and have the potential to further understand the relationship between post-translational modification (PTM) levels of proteins and different molecular and clinical features of HCC patients.

Crotonylomics sequencing of human non small cell lung cancer cell lines

Project description:Crotonylation is a crotonyl-coenzyme A (CoA)-mediated post-translational modification best known for its roles in epigenetic regulation. Histone lysine crotonylation (Kcr) has been reported to be involved in tumor-related biological functions such as DNA damage repair and immune infiltration. Here we find that abnormal reduction of histone Kcr significantly correlates with a poor response to epithelial growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in in-house-established drug-resistant models of lung cancer cell lines, and in cell line-derived xenograft (CDX) and patient-derived xenograft (PDX) models. The crotonyl-CoA-producing enzyme ACSS2 is the key regulator of the resistance-related change of crotonylation. Quantitative crotonylomic, transcriptomic and epigenomic analyses reveal that EGFR-TKI resistance is accompanied by reduced levels of histone 3 lysine 56 crotonylation (H3K56cr) on chromatin, which inhibits transcription of HNF1A and activates the PI3K/AKT signaling pathway. Studies of patient-derived organoids (PDOs) and resistant lung cancer CDX and PDX models treated with a novel histone decrotonylase (HDCR) inhibitor, S67, demonstrate that up-regulation of H3K56cr sensitizes cells to the effect of EGFR-TKIs. These findings uncover the role of histone Kcr in resistance to EGFR-TKIs and suggest a new combination therapy in lung cancer.

Succinylation proteome analysis of Cd-exposed Neuro-2a cells

Project description:Cadmium is a neurotoxic compound which induces cognitive alterations similar to those produced by Alzheimer's disease (AD). Autophagic flux impairment is a hallmark in Cd-induced AD-like pathology. However, the underlying mechanism remains obscure. In these study, Neuro-2a cells were exposed to different concentrations of Cd (1, 2, and 4 μM) for 72 h, and C57 mice (8 week) were orally administered Cd for 12 weeks. Chronic Cd exposure inhibited autophagosome-lysosome fusion and impaired lysosomal function, thereby contributing to defects in autophagic clearance and subsequently leading to APP accumulation and nerve cell death. Mechanistically, proteomic analysis coupled with Ingenuity Pathway Analysis identified the crucial key target molecule in Cd-impaired autophagic flux. Four-dimensional label-free succinylation quantitative proteomics were performed in Neuro-2a cells with and without 4 μM CdCl2 treatment for 72h. Then, vital molecules and crucial succinylation sites were identified. Moreover, the function and important role of the resulting molecule with crucial succinylation site were determined. These results may thus open an avenue for therapeutic intervention in chronic Cd-induced AD-like pathology.

Comprehensive ubiquitomics characterization identify biomarkers of liver cancer subtypes

Project description:Hepatocellular carcinoma (HCC) has been widely studied at multi-omics level, but little is known about its specific ubiquitination, a major post-translational modification (PTM). In this study, we performed the ubiquitomics data collected from 85 HCC tumors and 18 adjacent normal tissues (ANTs) to establish the ubiquitomic profiles of HCC and reveal tumor-associated characteristics with prognosis and clinical outcomes. Ubiquitomic based stratification of HCC revealed three subtypes related to different clinical and molecular features, suggesting ubiquitomics have the potential to further understand the relationship between ubiquitination levels of proteins and different molecular and clinical features of HCC patients.

Selective androgen receptor degrader (SARD) to overcome antiandrogen resistance in castration-resistant prostate cancer

Project description:Clinical resistance such as androgen receptor (AR) mutation, AR overexpression, and AR splice variants (ARVs) restrict the second-generation antiandrogens benefit in patients with castration-resistant prostate cancer (CRPC). Several strategies have been implemented to develop novel antiandrogens to circumvent the occurring resistance. In this study, based on rational drug design, we discovered and identified a bifunctional small molecule Z15 as a potent AR antagonist and AR selective degrader. Z15 could directly bind to the AR ligand-binding domain (LBD) and inhibited DHT-induced AR nuclear translocation. Furthermore, Z15 promoted AR degradation through the proteasome pathway. As a result, our in vitro and in vivo studies showed Z15 efficiently suppressed AR and AR mutant transcription activity, downregulated mRNA and protein levels of AR target genes, as well as overcame AR LBD mutations, AR amplification, and ARVs-induced resistance in CRPC. In conclusion, our data illustrate the synergistic importance of AR antagonism and degradation in advanced prostate cancer treatment.

Discovery of a small molecule inhibitor of the UBE2F-CRL5 axis that induces apoptosis and G2/M arrest and confers radiosensitization

Project description:Protein neddylation modification is catalyzed by a neddylation activating enzyme (NAE, E1), an E2 conjugating enzyme and an E3 ligase. In various types of human cancers, the neddylation pathway was abnormally activated. Our previous study validated that neddylation E2 UBE2F is a promising lung cancer target. However, although NAE inhibitor MLN4924/pevonedistat is currently in few clinical trials for anticancer application, no small molecule was reported that targets UBE2F. Here, we report, for the first time, the discovery, via structure-based virtual screen and chemical optimization, of such a small molecule, designated as HA-9104. HA-9104 binds to UBE2F, reduces its protein levels, and consequently inhibits cullin-5 neddylation to inactivate CRL5 (cullin-RING ligase-5) ligase, leading to accumulation of CRL5 substrate, NOXA, to induce apoptosis. Moreover, HA-9104 appears to form the DNA adduct via its 7-azaindole group to induce DNA damage and G2/M arrest. Biologically, HA-9104 effectively suppresses the growth and survival of lung cancer cells and confers radiosensitization in both in vitro cell culture and in vivo xenograft tumor models. Taken together, our study discovered a small molecule HA-9104 that targets the UBE2F-CRL5 axis with anticancer activity alone or in combination with radiation.
