CSRP2 promotes the glioblastoma mesenchymal phenotype via p130Cas-mediated NF-κB and MAPK pathways.

Background: Cysteine-rich protein 2 (CSRP2) plays a role in a variety of biological processes including cell proliferation and differentiation. However, whether and how CSRP2 participates in the malignancy of glioblastoma multiforme (GBM), including its proneural-to-mesenchymal transition (PMT), remains unclear.

Methods: CSRP2 expression in low-grade and high-grade gliomas was analyzed, and survival analyses were performed in patients with gliomas with high and low CSRP2 expression in various tumor databases.

Revision and expansion of the genus Spirirestis (Tolypothrichaceae, Cyanobacteria).

Recent phylogenetic analyses of members of the Tolypothrichaceae (Nostocales, Cyanobacteria) based on 16S rRNA gene sequence data have demonstrated that the soil-inhabiting members of the family belong to a clade separate from the aquatic and subaerial members of the family. The soil-inhabiting species clade includes Spirirestis, a monophyletic taxon originally defined by its tight spiral coiling. Most of the soil-inhabiting species have been identified in the past as belonging either to Hassallia or Tolypothrix, which are subaerial and aquatic taxa, respectively.

Robust prediction of glioma prognosis by hypoxia-induced ferroptosis genes: VEGFA-XBP1 co-expression for salvage therapy.

Tandem Silicon Photovoltaic/Hydrovoltaic Devices for Synergistic Utilization of Solar Energy.

In conventional photovoltaic (PV) devices, sub-bandgap photons remain unutilized, contributing to heat accumulation and temperature-induced efficiency losses. Here, we present a tandem silicon photovoltaic/hydrovoltaic (PV/HV) device designed for synergistic and highly efficient solar energy utilization. In this configuration, photons with energies above the silicon bandgap drive PV electricity generation, while the remaining solar energy is converted into thermal energy to facilitate water evaporation, enabling HV electricity generation and water purification.

Effectiveness and safety of stellate ganglion block with trioxygen autologous blood retransfusion therapy for facial postherpetic neuralgia in elderly patients.

This study evaluated the efficacy and safety of stellate ganglion block (SGB) combined with trioxygen autologous blood retransfusion therapy (TABRT) in treating postherpetic neuralgia (PHN) of the head and face in elderly patients. A total of 190 patients (aged ≥ 60 years) with PHN were randomly assigned to receive either drug treatment alone (Group D, n = 40), drug treatment with SGB (Group DS, n = 52), drug treatment with TABRT (Group DT, n = 53), or drug combined SGB with TABRT (Group DST, n = 45). Key outcomes included pain visual analogue scale (VAS) scores and anxiety levels at baseline, 7 days, and 15 days post-treatment, the need for salvage analgesics, and complication rates assessed.

Pan-cancer analysis reveals SMARCAL1 expression is associated with immune cell infiltration and poor prognosis in various cancers.

Although immune checkpoint inhibition in particular has shown promise in cancer immunotherapy, it is not always efficient. Recent studies suggest that SMARCAL1 may play a role in tumor immune evasion, yet its pan-cancer role is unclear. We conducted a comprehensive analysis of SMARCAL1 using TCGA, GTEx, and CCLE databases, evaluating its expression, genetic alterations, epigenetic modifications, and their clinical correlations across 33 cancer types.

Convolutional neural network-assisted Raman spectroscopy for high-precision diagnosis of glioblastoma.

Glioblastoma multiforme (GBM) is the most lethal intracranial tumor with a median survival of approximately 15 months. Due to its highly invasive properties, it is particularly difficult to accurately identify the tumor margins intraoperatively. The current gold standard for diagnosing GBM during surgery is pathology, but it is time-consuming.

In Vitro Characterization of Inhibition Function of Calcifediol to the Protease Activity of SARS-COV-2 PLpro.

Vitamin D3 and its metabolites calcifediol have been recommended as effective drugs for novel coronavirus disease 2019 (COVID-19) therapy in many studies, since the outbreak of this global dramatic pandemic. In this study, we made a striking discovery that Calcifediol demonstrates robust inhibitive effect on the of the papain-like cysteine protease (PLpro), a critical proteolytic enzyme for the severe acute respiratory syndrome coronavirus-2(SARS-COV-2), through a small-scale FRET-based screening experiment. The practical bindings of Calcifediol to PLpro were also demonstrated by several in vitro interaction studies.

Ketogenic β-hydroxybutyrate regulates β-hydroxybutyrylation of TCA cycle-associated enzymes and attenuates disease-associated pathologies in Alzheimer's mice.

Lysine β-hydroxybutyrylation (Kbhb) is a post-translational modification that has recently been found to regulate protein functions. However, whether and how protein Kbhb modification participates in Alzheimer's disease (AD) remains unknown. Herein, we carried out 4D label-free β-hydroxybutylation quantitative proteomics using brain samples of 8-month-old and 2-month-old APP/PS1 AD model mice and wild-type (WT) controls.

The proto-oncogene tyrosine kinase c-SRC facilitates glioblastoma progression by remodeling fatty acid synthesis.

Increased fatty acid synthesis benefits glioblastoma malignancy. However, the coordinated regulation of cytosolic acetyl-CoA production, the exclusive substrate for fatty acid synthesis, remains unclear. Here, we show that proto-oncogene tyrosine kinase c-SRC is activated in glioblastoma and remodels cytosolic acetyl-CoA production for fatty acid synthesis.

The combination of temozolomide and perifosine synergistically inhibit glioblastoma by impeding DNA repair and inducing apoptosis.

Temozolomide (TMZ) is widely utilized as the primary chemotherapeutic intervention for glioblastoma. However, the clinical use of TMZ is limited by its various side effects and resistance to chemotherapy. The present study revealed the synergistic inhibition of glioblastoma through the combined administration of TMZ and perifosine.

Advances in Nanodynamic Therapy for Cancer Treatment.

Nanodynamic therapy (NDT) exerts its anti-tumor effect by activating nanosensitizers to generate large amounts of reactive oxygen species (ROS) in tumor cells. NDT enhances tumor-specific targeting and selectivity by leveraging the tumor microenvironment (TME) and mechanisms that boost anti-tumor immune responses. It also minimizes damage to surrounding healthy tissues and enhances cytotoxicity in tumor cells, showing promise in cancer treatment, with significant potential.
