... Hijacking the cellular protein degradation system offers unique opportunities for drug discovery, as exemplified by proteolysis-targeting chimeras. Despite their great promise for medical chemistry, so far, it has not been possible to reprogram the bacterial degradation machinery to interfere with microbial infections. Here, we develop small-molecule degraders, so-called BacPROTACs, that bind to t ...

Abstract:
... Targeted protein degradation (TPD) strategies have revolutionized how scientists tackle challenging protein targets deemed undruggable with traditional small molecule inhibitors. Many promising campaigns to inhibit proteins have failed due to factors surrounding inhibition selectivity and targeting of compounds to specific tissues and cell types. One of the major improvements that PROTAC (proteoly ...

Abstract:
... In this study, we identified 3-aminophthalic acid as a new ligand of cereblon (CRBN) E3 ubiquitin ligase and developed a phthalic acid-based O’PROTAC for degradation of the ERG transcription factor. This phthalic acid-based O’PROTAC presented an efficacy in degrading ERG comparable to those displayed by pomalidomide-based ERG O’PROTACs. Moreover, phthalic acid—being more chemically stable and econ ...

Abstract:
... Targeting deubiquitinating enzymes (DUBs) has emerged as a promising therapeutic approach in several human cancers and other diseases. DUB inhibitors are exciting pharmacological tools but often exhibit limited cellular potency. Here we report PROTACs based on a ubiquitin-specific protease 7 (USP7) inhibitor scaffold to degrade USP7. By investigating several linker and E3 ligand types, including n ...

Abstract:
... In this study, co-hydrothermal carbonization of rape straw and microalgae was conducted for clean hydrochar. The effect of different feedwater pH values (pH = 1, 3, 5, 7, 9, 12) on co-HTC and the mechanism of enhanced N, S, and O removal were revealed. The acidic and alkaline environment of the feedwater exacerbates the carbonization process. The higher heating value (HHV) of the hydrochar formed ...

Abstract:
... Proteolysis-targeting chimeras (PROTACs), heterobifunctional compounds that consist of protein-targeting ligands linked to an E3 ligase recruiter, have arisen as a powerful therapeutic modality for targeted protein degradation (TPD). Despite the popularity of TPD approaches in drug discovery, only a small number of E3 ligase recruiters are available for the >600 E3 ligases that exist in human cell ...

Abstract:
... Protein degradation occurs through proteasomal, endosomal, and lysosomal pathways. Technological advancements have allowed for the determination of protein copy numbers and turnover rates on a global scale, which has provided an overview of trends and rules governing protein degradation. Sharper chemical and gene-editing tools have enabled the specific perturbation of each degradation pathway, who ...

Abstract:
... The bromodomain and extraterminal motif (BET) proteins are critical drug targets for diseases. The precise functions and relationship of BRD2 with other BET proteins remain elusive mechanistically. Here, we used acute protein degradation and quantitative genomic and proteomic approaches to investigate the primary functions of BRD2 in transcription. We report that BRD2 is required for TAF3-mediated ...

Abstract:
... The aim of this study was to determine the effects of tumbling at different post‐mortem times on the proteolytic features and quality attributes of beef loins (M. longissimus lumborum). Loins (n = 12) were cut into 4 sections and assigned to tumbling at 1, 6 or 11 days post‐mortem or non‐tumbled control. Upon tumbling, additional ageing was applied to a common post‐mortem time of 16 days. In gener ...

Abstract:
... Oligomannose-type glycans on glycoproteins play an important role in the endoplasmic reticulum (ER)-protein quality control. Mannose trimming of the glycans triggers the ER-associated protein degradation pathway. In mammals, ER mannosyl-oligosaccharide 1,2-α-mannosidase 1 and three ER degradation -enhancing α-mannosidase-like proteins (EDEMs) are responsible for mannose trimming. However, the exac ...

Abstract:
... The plant hormone auxin acts through regulated degradation of Auxin/INDOLE-3-ACETIC ACID (Aux/IAA) proteins to regulate transcriptional events. In this review, we examine the composition and function of each Aux/IAA structural motif. We then focus on recent characterization of Aux/IAA N-terminal disordered regions, formation of secondary structure within these disordered regions, and post-translat ...

Abstract:
... Targeted protein degradation has exploded over the past several years due to preclinical and early clinical therapeutic success of numerous compounds, and the emergence of new degradation modalities, which has broadened the definition of what a degrader is. The most characterized and well-studied small molecule degraders are molecular glues and proteolysis targeting chimeras (PROTACs). These degra ...

In this study, we examined the effects of marination with five edible mushroom powders (3%, m/m) on the quality attributes and protein changes of pork longissimus dorsi compared to meat marinated with 0.2% papain and distilled water (control group). The results indicated that pork samples marinated with edible mushrooms displayed better water retention and lower shear force, especially in the 3% H ...

Abstract:
... The subcellular distribution of calpain-1 and -2 and the proteolytical activity of myofibril-bound calpains in pork were investigated during 12 days cold storage. The content of sarcoplasmic calpain-1 decreased during storage while myofibril-bound calpain-1 content first increased (P < 0.05) to 17% of that of 12 h-sarcoplasmic calpain-1 on day 6 followed by a gradual decrease with subsequent stora ...

Here, we revealed the crucial role of CDC48B in regulating periclinal cell division in roots by analyzing the recessive gen1 mutant. We identified the GEN1 gene through map‐based cloning and verified that GEN1 encodes CDC48B. gen1 showed severely inhibited root growth, incre ...

Abstract:
... Plasma glucose levels are homeostatically regulated within strict boundaries and are maintained through a balance between peripheral glucose uptake and hepatic glucose production. However, little is known about the regulatory mechanism of glucose uptake in adipocytes during fasting. Under fasting conditions, the expression levels of 8 glycolytic enzymes were significantly reduced in adipose tissue ...

Abstract:
... Lipid oxidation and/or protein decomposition caused by endogenous enzymatic activity and microbial contamination have a negative impact on the quality of fish in storage, increasing their perishability. Safe and effective alternative approaches for preserving fish quality and extending their shelf-life have been investigated more intensely over the recent decade, due to concerns about the safety o ...

Abstract:
... Decreases in chlorophyll and photosynthetic efficiency co-occur during aging and leaf senescence. Here, we report the positive functions of melatonin (MT) in delaying leaf senescence in cucumber plants. The results showed that natural leaf senescence induced the accumulation of endogenous MT and that spraying MT delayed leaf senescence in a concentration-dependent manner. Moreover, application of ...

In addition to global warming, marine pollutants are another important factor causing the breakdown of coral symbiosis. Benzo(a)pyrene (BaP) is a globally widespread marine environmental pollutant that poses a severe threat to marine ecosystems. However, responses of coral symbionts to global marine ...
