A Selection of Mechanisms Relevant to Atherosclerosis
Atherosclerosis is the growth of fatty lesions in blood vessel walls, leading eventually to a rupture and blockage to cause a heart attack or stroke, and along the way causing narrowing of blood vessels sufficient to lead to heart failure and dysfunction elsewhere in the body as the supply of blood to tissues is reduced. Today's paper on this topic is a little disorganized, something of a random assembly of thoughts on mechanisms relevant to the development of atherosclerosis. Atherosclerosis is the single largest cause of human mortality, and attempts to treat contributing mechanisms have so far not stopped it from being ...

Inhibition of STIM1 alleviates high glucose-induced proliferation and fibrosis by inducing autophagy in mesangial cells
In this study, we investigated the role of STIM1 in the proliferation and fibrosis in high glucose (HG)-induced HBZY-1 cells. We found that the expression of STIM1 was increased in renal tissues of diabetic rat and HBZY-1 cells stimulated by HG. Downregulation of STIM1-mediated SOCE suppressed hyperglycemic cell proliferation and fibrosis by activating autophagy. In addition, the inhibitory effect of downregulating STIM1 on cells was blocked by autophagy inhibitor Bafilomycin A1 (BafA1). Moreover, this experiment also showed that STIM1 regulated autophagy, cell proliferation and fibrosis via PI3K/AKT/mTOR signal pathway. T...

Evaluation of enhanced permeability effect and different linear energy transfer of radionuclides in a prostate cancer xenograft model
In conclusion, we found that specific targeting might negatively influence normal organ uptake when targeting secreted antigens. Furthermore, different energy deposition i.e. linear energy transfer of a radionuclide might have diverse effects on receptor expression and cell proliferation in tumors.PMID:37736493 | PMC:PMC10509292

The role of 18F-fluorodeoxyglucose PET/computed tomography in the diagnosis and monitoring of large vessel vasculitides - a review article
Am J Nucl Med Mol Imaging. 2023 Aug 15;13(4):127-135. eCollection 2023.ABSTRACTIn the last two decades, advancements in positron emission tomography (PET) technology have increased the diagnostic accuracy of patients with large-vessel vasculitis (LVV). Numerous systematic reviews and meta-analyses have been conducted, and patients suspected of having LVV can be diagnosed earlier with 18F-FDG PET. Two subtypes, giant cell arteritis (GCA) and Takayasu arteritis (TA), will progress when their response to corticosteroids and enhanced immunosuppression is inadequate. In the majority of patients, disease activity cannot be monit...

Time-resolved cryo-EM (TR-EM) analysis of substrate polyubiquitination by the RING E3 anaphase-promoting complex/cyclosome (APC/C)
Nat Struct Mol Biol. 2023 Sep 21. doi: 10.1038/s41594-023-01105-5. Online ahead of print.ABSTRACTSubstrate polyubiquitination drives a myriad of cellular processes, including the cell cycle, apoptosis and immune responses. Polyubiquitination is highly dynamic, and obtaining mechanistic insight has thus far required artificially trapped structures to stabilize specific steps along the enzymatic process. So far, how any ubiquitin ligase builds a proteasomal degradation signal, which is canonically regarded as four or more ubiquitins, remains unclear. Here we present time-resolved cryogenic electron microscopy studies of the ...

Searching for bacteria able to metabolize polycyclic aromatic sulfur compounds in 12-years periodically fed bioreactor
This study aimed to identify microorganisms capable of degrading PASC in such environments. Among the 20 colonies isolated from an inoculum containing DBT as the sole sulfur source, only four isolates exhibited amplification of the dszA gene in the dszABC operon. The production of 2-hydroxybiphenyl (HPB) and a decrease in DBT were detected during the growth curve and resting cell assays. The isolates were identified using 16S rRNA sequencing belonging to the genera Stutzerimonas and Pseudomonas. These isolates demonstrated significant potential for biodesulfurization and/or degradation of PASC. All isolates possessed the p...

Oxidized galectin-1 in SLE fails to bind the inhibitory receptor VSTM1 and increases reactive oxygen species levels in neutrophils
Cell Mol Immunol. 2023 Sep 22. doi: 10.1038/s41423-023-01084-z. Online ahead of print.ABSTRACTInhibitory immune receptors set thresholds for immune cell activation, and their deficiency predisposes a person to autoimmune responses. However, the agonists of inhibitory immune receptors remain largely unknown, representing untapped sources of treatments for autoimmune diseases. Here, we show that V-set and transmembrane domain-containing 1 (VSTM1) is an inhibitory receptor and that its binding by the competent ligand soluble galectin-1 (Gal1) is essential for maintaining neutrophil viability mediated by downregulated reactive...

Modeling unveils sex differences of signaling networks in mouse embryonic stem cells
Mol Syst Biol. 2023 Sep 21:e11510. doi: 10.15252/msb.202211510. Online ahead of print.ABSTRACTFor a short period during early development of mammalian embryos, both X chromosomes in females are active, before dosage compensation is ensured through X-chromosome inactivation. In female mouse embryonic stem cells (mESCs), which carry two active X chromosomes, increased X-dosage affects cell signaling and impairs differentiation. The underlying mechanisms, however, remain poorly understood. To dissect X-dosage effects on the signaling network in mESCs, we combine systematic perturbation experiments with mathematical modeling. ...

PARylated PDHE1 α generates acetyl-CoA for local chromatin acetylation and DNA damage repair
Nat Struct Mol Biol. 2023 Sep 21. doi: 10.1038/s41594-023-01107-3. Online ahead of print.ABSTRACTChromatin relaxation is a prerequisite for the DNA repair machinery to access double-strand breaks (DSBs). Local histones around the DSBs then undergo prompt changes in acetylation status, but how the large demands of acetyl-CoA are met is unclear. Here, we report that pyruvate dehydrogenase 1α (PDHE1α) catalyzes pyruvate metabolism to rapidly provide acetyl-CoA in response to DNA damage. We show that PDHE1α is quickly recruited to chromatin in a polyADP-ribosylation-dependent manner, which drives acetyl-CoA generation to su...

Identification and characterisation of a major outer membrane protein from Methylacidiphilum fumariolicum SolV
In this study, we identified and characterised a major outer membrane protein (WP_009059494) from Methylacidiphilum fumariolicum SolV. PRED-TMBB and AlphaFold2 predicted this protein to form a porin with a β-barrel structure consisting of ten antiparallel β-sheets and with a small amphipathic N-terminal α-helix in the periplasm. We purified soluble recombinant protein WP_009059494 from E. coli using Tris-HCl buffer with SDS. Antibodies were raised against two peptides in the two large extracellular loops of protein WP_009059494 and immunogold localisation showed this protein to be mainly present in the OM of strain SolV...
