Reinvestigation into the role of lipopolysaccharide Glycosyltransferases in protein glycosylation.

Protein glycosylation has been considered as a fundamental phenomenon shared by all domains of life. In , glycosylation of flagellins A and B with pseudaminic acid have been rigorously confirmed and shown to be essential for flagella assembly and bacterial colonization. In addition to flagellins, several other proteins including RecA, AlpA/B, and BabA/B in have also been reported to be glycosylated and to be dependent on the lipopolysaccharide (LPS) biosynthetic pathway.

Pandemic driven preoperative moderate hypofractionated radiotherapy for soft tissue sarcomas.

Purpose: Moderate hypofractionation was adopted to reduce hospital visits during the COVID-19 pandemic aiming to maintain treatment efficacy for soft tissue sarcoma (STS) patients, shifting preoperative schedules from 25 fractions of 2 Gy to 14-15 fractions of 3 Gy. This study evaluates the clinical implications and outcomes of this schedule, focusing on wound complications, radiation toxicity, local tumour control, and distant metastases.

Patients And Methods: Data was collected from patients treated between 01 and 01-2020 and 31-12-2023.

Long-term survival of participants in the PASART-1 and PASART-2 trials of neo-adjuvant pazopanib and radiotherapy in soft tissue sarcoma.

Objective: This study aims to assess the long-term safety and efficacy of adding pazopanib to neo-adjuvant radiotherapy followed by surgery in patients with high-risk non-metastatic soft tissue sarcoma of the trunk and extremities treated in the PASART-1 and PASART-2 trials, as well as to compare the PASART cohorts to a control cohort receiving standard treatment during the same time period from the Netherlands Cancer Registry (IKNL) to investigate if adding pazopanib improves Overall Survival (OS).

Methods: Updated follow-up data on disease control, survival and long-term toxicities of the PASART-trials were extracted from electronic patient records. The effect of adding pazopanib to neo-adjuvant radiotherapy on OS was investigated by comparing the combined PASART cohorts to the IKNL cohort via direct comparison and exact matching analysis.

Accelerated growth and local progression of radiorecurrent prostate cancer in an orthotopic bioluminescent mouse model.

Globally, prostate cancer is the second most common malignancy in males, with over 400 thousand men dying from the disease each year. A common treatment modality for localized prostate cancer is radiotherapy. However, up to half of high-risk patients can relapse with radiorecurrent prostate cancer, the aggressive clinical progression of which remains severely understudied.

The sedoheptulose kinase CARKL controls T-cell cytokine outputs and migration by promoting metabolic reprogramming.

Background: Immunometabolism is a crucial determinant of immune cell function, influencing cellular activation and differentiation through metabolic pathways. The intricate interplay between metabolism and immune responses is highlighted by the distinct metabolic programs utilized by immune cells to support their functions. Of particular interest is the pentose phosphate pathway (PPP), a key metabolic pathway branching out of glycolysis that plays a pivotal role in generating NADPH and pentose sugars crucial for antioxidant defense and biosynthesis.

Methods: The CHPCA Meeting is an academy-styled annual conference organized by the Prostate Cancer Foundation, to focus discussion on the most critical emerging research that have the greatest potential to advance knowledge of prostate cancer biology and treatment. The 2024 CHPCA Meeting was attended by 75 academic investigators and included 37 talks across 8 sessions.

Colibactin Exerts Androgen-dependent and -independent Effects on Prostate Cancer.

Background And Objective: The etiology of prostate cancer (PC) is multifactorial and poorly understood. It has been suggested that colibactin-producing Escherichia coli positive for the pathogenicity island pks (pks) initiate cancers via induction of genomic instability. In PC, androgens promote oncogenic translocations.

Antineoplastic therapy affects the in vitro phenotype and functionality of healthy human bone marrow-derived mesenchymal stromal cells.

While antineoplastic therapies aim to specifically target cancer cells, they may also exert adverse effects on healthy tissues, like healthy hematopoietic stem and progenitor cells (HSPC), leading to hematotoxicity as a common side effect. Mesenchymal stromal cells (MSC) are a major component of the bone marrow (BM) microenvironment, regulating normal hematopoiesis, while their susceptibility to anticancer therapies and contribution to therapy-related hematotoxicity remains largely unexplored. To address this, we investigated the effects of etoposide, temozolomide, 5-azacitidine, and venetoclax on healthy BM-derived MSC functionality.

Neoadjuvant chemotherapy for radiation associated angiosarcoma (RAAS) of the breast: A retrospective single center study.

Background: Radiation associated angiosarcoma (RAAS) of the breast is a rare malignancy with poor survival. Optimal treatment strategies remain uncertain due to a lack of data, and vary between surgery alone and a combination of surgery with (neo)adjuvant chemotherapy (NACT) and/or re-irradiation. The aim of this study was to evaluate the potential benefit of taxane based NACT.

The translatome of glioblastoma.

Glioblastoma (GB), the most common and aggressive brain tumor, demonstrates intrinsic resistance to current therapies, resulting in poor clinical outcomes. Cancer progression can be partially attributed to the deregulation of protein translation mechanisms that drive cancer cell growth. In this study, we present the translatome landscape of GB as a valuable data resource.

How Do Australians Manage Diagnostic Testing Risks? Focus Groups Linked to a Model of Behaviour Change.

Background: Diagnostic tests carry significant risks, and communications are needed to help lay people consider these. The development of communications has been hindered by poor knowledge about how lay people understand and negotiate testing risks. We examined lay Australians' perceptions of diagnostic testing risks and how these risks are managed.

Elastin-like polypeptide coacervates as reversibly triggerable compartments for synthetic cells.

Compartmentalization is a vital aspect of living cells to orchestrate intracellular processes. In a similar vein, constructing dynamic and responsive sub-compartments is key to synthetic cell engineering. In recent years, liquid-liquid phase separation via coacervation has offered an innovative avenue for creating membraneless organelles (MOs) within artificial cells.

Methods: Patient dataset analysis was conducted using a variety of prostate cancer cohorts.

Fluorinated Amide-Based Electrolytes Induce a Sustained Low-Charging Voltage Plateau under Conditions Verifying the Feasibility of Achieving 500 Wh kg Class Li-O Batteries.

Although lithium-oxygen batteries (LOBs) hold the promise of high gravimetric energy density, this potential is hindered by high charging voltages. To ensure that the charging voltage remains low, it is crucial to generate discharge products that can be easily decomposed during the successive charging process. In this study, we discovered that the use of amide-based electrolyte solvents containing a fluorinated moiety can notably establish a sustained voltage plateau at low-charging voltages at around 3.
