COLD6-OSM1 module senses chilling for the tolerance via 2',3'-cAMP signal in rice

ABSTRACT: To further elucidate how COLD6 regulates rice chilling tolerance, we investigated COLD6 interacting proteins using COLD6ind-GFP transgenic line by immunoprecipitation in combination with mass spectrometry (IP-MS). COLD6ind-GFP was applied to bind proteins in chilling-treated rice seedling samples, and the proteins bound at the plasma membrane were subsequently extracted for further analysis. We identified 44 potential interacted proteins with COLD6.Osmotin-like protein (OSM1, LOC_Os12g38170), known for its involvement in plant abiotic stress, was found in two independent experiments.

While it is known that temperature sensors trigger calcium (Ca<sup>2+</sup>) signaling to confer cold tolerance in cells, less is known about sensors that couple with other secondary messengers. Here, we identify a cold sensor complex of CHILLING-TOLERANCE DIVERGENCE 6 (COLD6) and osmotin-like 1 (OSM1), which triggers 2',3'-cyclic adenosine monophosphate (2',3'-cAMP) production to enhance cold tolerance in rice. COLD6, which is encoded by a major quantitative trait locus (QTL) gene, interacts wi ...[more]

NLRP6 controls PTEN stability by promoting autophagic degradation of p85α to drive tumorigenesis

Project description:To identify NLRP6-associated proteins in living cells, we applied an APEX2-based labelling method combined with mass spectrometry. In brief, APEX2 was genetically fused to NLRP6. In the presence of hydrogen peroxide, APEX2 catalysed biotin-phenol to become a biotin-phenol radical that covalently bound to NLRP6 neighbouring proteins (<20 nm). The biotinylated proteins were enriched and collected by streptavidin beads. One-dimensional SDS–PAGE followed by liquid chromatography-tandem mass spectrometry (GeLC–MS/MS) was performed to identify the proteins. To detect ubiquitinated p85α, a Flag-tagged p85α plasmid was transfected into cells. The cell lysates were immunoprecipitated with anti-Flag and separated on a 6% SDS–PAGE gel. After in-gel digestion, the resulting peptides were extracted for GeLC–MS/MS analysis.

Deubiquitinase JOSD2 promotes non-small cell lung cancer proliferation via deubiquitylation and inactivation of LKB1

Project description:Deubiquitinases (DUBs), frequently overactivated in cancers, are associated with tumorigenesis and regarded as promising therapeutic targets. However, the underlying mechanism of DUBs promoting non-small cell lung cancer (NSCLC) are poorly understood. Through a global analysis of the contribution of 97 DUBs in NSCLC survival possibilities by The Cancer Genome Atlas (TCGA) database, we found that high expression of Josephin Domain-containing protein 2 (JOSD2) predicted the poor prognosis of patients. Depletion of JOSD2 significantly impeded NSCLC growth in vivo in both cell/patient-derived xenografts. Mechanistically, JOSD2 inhibits LKB1 kinase activity by removing K6-linked polyubiquitination, which was critical for maintaining LKB1-STRAD-MO25 complex integrity. Furthermore, we identified the first small molecule inhibitor of JOSD2 and the pharmacological inhibition of JOSD2 significantly arrested NSCLC proliferation in vitro/in vivo. Notably, our findings demonstrate a crucial role of JOSD2 in hindering LKB1 activity, highlighting JOSD2 as a potential therapeutic target in NSCLC and providing its inhibitors as a promising strategy for NSCLC treatment.

Josephin Domain Containing 2 (JOSD2) Inhibition as Pan-KRAS-Mutation-Targeting Strategy for Colorectal Cancer

Project description:KRAS is the most common mutated oncogenes in colorectal cancer (CRC), yet effective therapeutic strategies for targeting multiple KRAS-mutations remained challenging. The prolonged protein stability of KRAS mutants contribute to their robust tumor-promoting effects, but the underlying mechanism is elusive. Herein by screening deubiquitinases (DUBs) siRNA library, we identified Josephin domain containing 2 (JOSD2) functions as a potent DUB that regulates the protein stability of KRAS mutants. Mechanistically, JOSD2 directly interacted with and stabilized KRAS variants across different mutants, by reverting their proteolytic ubiquitination; while KRAS mutants reciprocally inhibited the catalytic activity of CHIP, a bona fide E3 ubiquitin ligase for JOSD2, thus forming a JOSD2/KRAS positive feedback circuit that significantly accelerated KRAS-mutant CRC growth. Inhibition of JOSD2 by RNA interference or its pharmacological inhibitor promoted the polyubiquitination and proteasomal degradation of KRAS mutants, and preferentially impeded the growth of KRAS-mutant CRC including patient-derived cells/xenografts/organoids (PDCs/PDXs/PDOs) over that harboring wild-type KRAS. Collectively, this study not only revealed the crucial roles of JOSD2/KRAS positive feedback circuit in KRAS-mutant CRC, but also provides a rationale to target JOSD2 as the promising pan-KRAS-mutation-targeting strategy for the treatment of a broad population of CRC patients with KRAS variant across different mutant types.

Pharmacological Targeting of Casein Kinase 1δ Suppresses Oncogenic NRAS-Driven Melanoma

Project description:Activating mutations in NRAS account for 15-20% of melanoma, yet effective anti-NRAS therapies are still lacking. In this study, we unveil the casein kinase 1δ (CK1δ) as an uncharacterized regulator of oncogenic NRAS mutations, specifically Q61R and Q61K, which are the most prevalent NRAS mutations in melanoma. The genetic ablation or pharmacological inhibition of CK1δ markedly destabilizes NRAS mutants and suppresses their oncogenic functions. Moreover, we identify USP46 as a bona fide deubiquitinase of NRAS mutants. Mechanistically, CK1δ directly phosphorylates USP46 and activates its deubiquitinase activity towards NRAS mutants, thus promoting oncogenic NRAS-driven melanocyte malignant transformation and melanoma progression in vitro and in vivo. Our findings underscore the significance of the CK1δ-USP46 axis in stabilizing oncogenic NRAS mutants and provide preclinical evidence that targeting this axis holds promise as a therapeutic strategy for human melanoma harboring NRAS mutations.

SILAC proteomics analysis to discover effect sensors of EGFR inhibition

Project description:Targeted therapies against EGFR show clinical benefit, but resistance to these agents invariably develops. Thus, there is a need for dynamic biomarkers - effect sensors - that reflect treatment with EGFR therapeutics during therapy. Making use of SILAC-labeling we aimed to discover plasma membrane proteins that become differentially expressed after treatment with EGFR inhibitor erlotinib in three erlotinib-sensitive breast cancer cell lines.

Myelin-axon interface disruption uncovered by subcellular proteomics and imaging of Alzheimer’s human brain

Project description:Myelin ensheathment enables efficient axonal electrical conduction, metabolic support, and regulates neuronal plasticity. Myelin and axon disruptions are involved in Alzheimer’s disease (AD), however, the precise mechanisms of how myelin and axons are decoupled remain poorly understood. Using novel subcellular proximity labeling proteomics, we characterizeduncovered the myelin-axon interface proteomeics in AD human postmortem brains and unaffected controls. We identified AD-dysregulated ligand-receptors and downstream signaling, such as amyloid processing and axonogenesis, that are involved in myelin-axon interaction. Using high resolution imaging approaches, we revealed structural abnormality of paranodes, and corroborated proteomic evidence showing intrusion of amyloid fibers at the internodal peri-axonal space and paranodal channels. We also revealed aberrant myelin and paranodes are associated with axonal spheroids around amyloid plaques. Together, this study reveals myelin-axon interface as a vulnerable site in AD, and provides novel techniques and resources to delineate the complex molecular and cellular interaction between myelin and axons in AD and beyond.

LC-MS/MS analysis of Gd-IgA1 and secretary TfR1 cross-linked complex

Project description:The retention of galactose-deficient IgA1 (Gd-IgA1) in the glomerular mesangium is a hallmark of IgA nephropathy (IgAN). The immune complex formed by Gd-IgA1 binds to transferrin receptor 1 (TfR1) and deposits on mesangial cell, inducing cell proliferation, inflammatory response, matrix secretion, etc., causes organic damage and dysfunction of the kidney. Even though, the mechanism of how Gd-IgA1 recognize and bind to TfR1 is unclear. In this experiment, we ami to determine the specific interaction region responsible for Gd-IgA1 and TfR1. We prepared a complex of Gd-IgA1 and TfR1 by incubating the two proteins under acidic conditions and stabilizing it using the chemical cross-linking agent glutaraldehyde. And then, the gel bands corresponding to the Gd-IgA1-TfR1 complex was exexcised from the SDS-PAGE gel and analyzed by high-resolution mass spectrometry. This analysis identified fragments containing the hinge peptide sequence, with the R276 residue interacting with the E350 and D356 residues in the apical domain of TfR1. Our results reveal that the hinge peptide of Gd-IgA1 interacts specifically with the apical domain of TfR1.
