Regulation of proteome homeostasis is crucial for the survival and adaptation to changing environments for all species. In eukaryotes, this process is finely tuned through regulation at the level of transcription, translation, protein modification, and protein degradation. The phospholipase A2 activating protein (PLAA) is present in all eukaryotes and believed to be a key player in ubiquitin-dependent protein sorting and degradation via its interactions with ubiquitin and/or the AAA+ ATPase, valosin-containing protein (VCP/p97).

The One-Pot PURE (rotein synthesis sing ecombinant lements) system simplifies the preparation of traditional PURE systems by coculturing and purifying 36 essential proteins for gene expression in a single step, enhancing accessibility and affordability for widespread laboratory adoption and customization. However, replicating this protocol to match the productivity of traditional PURE systems can take considerable time and effort due to uncharacterized variability. In this work, we observed unstable PURE protein expression in the original One-Pot PURE strains, M15/pREP4 and BL21(DE3), and addressed this issue using glucose-mediated catabolite repression to minimize burdensome background expression.

Human p97/VCP is a vital AAA ATPase (ATPase associated with diverse cellular activity) that plays critical roles in protein homeostasis by regulating autophagy, endosomal trafficking, and the ubiquitin-proteasome system. Global proteomics analysis of p97/VCP inhibition with CB-5083 has been performed in HCT116 colon cells. Here, we examined the impact of CB-5083 treatment in another cancer model, the HL-60 acute myeloid leukemia cell line, employing subcellular fractionation combined with label-free proteomics to analyze changes in protein levels across cytoplasmic, nuclear, and insoluble membrane protein compartments.

Rational design of defect engineering and interfacial built-in electric fields of photocatalysts is imperative for renewable energy conversion. Herein, a multi-strategy involving the introduction of Ni vacancies, the adjustment of the Se/S ratio, and the construction of dual junctions are employed to simultaneously realize NiSSe/phase junction CdS (HCC) an excellent photocatalytic activity and broad light absorption. With the help of V and the regulation of S/Se, the local electrons are redistributed to occupy more antibonding orbitals and adjust the p-band center, thus optimizing the H adsorption energy of the catalyst to accelerate the photocatalytic reaction kinetics.

The advancement of sophisticated instrumentation in mass spectrometry has catalyzed an in-depth exploration of complex proteomes. This exploration necessitates a nuanced balance in experimental design, particularly between quantitative precision and the enumeration of analytes detected. In bottom-up proteomics, a key challenge is that oversampling of abundant proteins can adversely affect the identification of a diverse array of unique proteins.

The rational design of the dimension and geometry of a plasmonic semiconductor cocatalyst is vitally important for efficient utilization of near-infrared (NIR) light and superior photocatalytic hydrogen generation. Herein, hollow cubic CuSe@CdS composites with different sizes and strong localized surface plasmon resonance (LSPR) were prepared by selenizing size-tunable CuO templates and loading CdS nanoparticles. The size of hollow cubic CuSe can affect the surface area and the conduction band potential through the size effect, regulating the carrier behavior of the CuSe@CdS heterojunction.

Background: In a phase 1b study, intravenous daratumumab plus pomalidomide and dexamethasone induced a very good partial response or better rate of 42% and was well tolerated in patients with heavily pretreated multiple myeloma. We aimed to evaluate whether daratumumab plus pomalidomide and dexamethasone would improve progression-free survival versus pomalidomide and dexamethasone alone in patients with previously treated multiple myeloma.

Methods: In this ongoing, open-label, randomised, phase 3 trial (APOLLO) done at 48 academic centres and hospitals across 12 European countries, eligible patients were aged 18 years or older, had relapsed or refractory multiple myeloma with measurable disease, had an Eastern Cooperative Oncology Group performance status of 0-2, had at least one previous line of therapy, including lenalidomide and a proteasome inhibitor, had a partial response or better to one or more previous lines of antimyeloma therapy, and were refractory to lenalidomide if only one previous line of therapy was received.

Sulfomycins are sulfur-rich, ribosomally synthesized, and post-translationally modified peptides (RiPPs) that are characterized by a 35-membered macrocyclic ring system with a pyridine domain central to five azoles and additional dehydroamino acids. The pathway through which these large thiopeptide antibiotics are formed in remains elusive. Starting with the cloning of the biosynthetic gene cluster of sulfomycins, we here dissect a two-stage process in which an unusual dehydrogenase heterotrimer functions with two distinct YcaO proteins to install five azole heterocycles into the core peptide sequence of the precursor peptide.
