While the centrality of posttranscriptional modifications to RNA biology has long been acknowledged, the function of the vast majority of modified sites remains to be discovered. Illustrative of this, there is not yet a discrete biological role assigned for one of the most highly conserved modifications, 5-methyluridine at position 54 in tRNAs (mU54). Here, we uncover contributions of mU54 to both tRNA maturation and protein synthesis.

Alterations in the size and number of endothelial fenestrae have been implicated in the pathogenesis of various diseases. The re-creation of fenestrated endothelium using human induced pluripotent stem cells (hiPSCs) provides a promising avenue to investigate the involvement of fenestrae in disease mechanisms and pharmacodynamics.

Human-induced pluripotent stem-cell (hiPSC)-derived VSMCs offer prospects for personalized disease modeling and regenerative strategies. Current research lacks comparative studies on the impact of three-dimensional (3D) substrate properties under cyclic strain on phenotypic adaptation in hiPSC-derived VSMCs.

This makes critical summaries of the evidence base difficult and sub-optimally informative for clinical practice guidelines and decision-making by patients and healthcare professionals. A solution is to develop a core outcome set (COS), an agreed minimum set of outcomes to be reported in all trials in a clinical area.
View Article and Find Full Text PDFRNAs are central to protein synthesis, with ribosomal RNA, transfer RNAs and messenger RNAs comprising the core components of the translation machinery. In addition to the four canonical bases (uracil, cytosine, adenine, and guanine) these RNAs contain an array of enzymatically incorporated chemical modifications. Transfer RNAs (tRNAs) are responsible for ferrying amino acids to the ribosome, and are among the most abundant and highly modified RNAs in the cell across all domains of life.
View Article and Find Full Text PDFContext: Outcomes in renal cell carcinoma (RCC) are reported inconsistently, with variability in definitions and measurement. Hence, it is difficult to compare intervention effectiveness and synthesise outcomes for systematic reviews and to create clinical practice guidelines. This uncertainty in the evidence makes it difficult to guide patient-clinician decision-making.

In 2021, the European Association of Urology RCC Guidelines Panel issued a weak recommendation for adjuvant pembrolizumab for high-risk ccRCC as defined by the trial until final overall survival data and results from other trials were available. Meanwhile, the primary DFS endpoints were not met for adjuvant atezolizumab (PD-L1 inhibitor; IMmotion010), adjuvant nivolumab plus ipilimumab (CheckMate 914), or perioperative nivolumab (PROSPER).

Here we provide an update summarising changes in the new WHO classification of renal tumours from a clinician perspective.
View Article and Find Full Text PDFOver the past decade, only minor changes have been introduced in the TNM staging system for renal cancer. Conversely, many milestones and modifications in management of the disease have been achieved, especially for patients with locally advanced and metastatic cancers. The European Association of Urology guidelines panel proposes a new TNM classification scheme for staging of renal cell carcinoma to reflect these breakthrough clinical improvements.

We have a limited understanding of brain metastasis tumor and immune biology, drivers of resistance to systemic treatment, and their overall poor prognosis. Current data support a multimodal treatment strategy with radiation treatment and/or surgery.

CIViC is a public domain, crowd-sourced, and adaptable knowledgebase of evidence for the Clinical Interpretation of Variants in Cancer, designed to reduce barriers to knowledge sharing and alleviate the variant interpretation bottleneck.

They translate (inter)national guidelines into local applicable protocols and clinical practice. The purpose of this article is to establish a multidisciplinary integrated care pathway for specialists and allied health care professionals in caring for individuals with von Hippel-Lindau (VHL) disease.
View Article and Find Full Text PDFVon Hippel-Lindau (VHL) disease is a hereditary cancer syndrome where individuals are predisposed to tumor development in the brain, adrenal gland, kidney, and other organs. It is caused by pathogenic variants in the VHL tumor suppressor gene. Standardized disease information has been difficult to collect due to the rarity and diversity of VHL patients.

Clinical phenotypes are heterogeneous both in terms of presentation of symptoms in the host and response to therapy. Several studies and initiatives have been established to analyse and review host genetic epidemiology associated with COVID-19.

Objective: To present a summary of the 2022 RCC guideline, which is based on a standardised methodology including systematic reviews (SRs) and provides transparent and reliable evidence for the management of RCC.
Evidence Acquisition: For the 2022 update, a new literature search was carried out with a cutoff date of May 28, 2021, covering the Medline, EMBASE, and Cochrane databases.
Unlabelled: The International Kidney Cancer Coalition (IKCC) is a federation of 46 affiliated patient organisations representing 1.2 million patients worldwide that is committed to reducing the global burden of kidney cancer. A large-scale global survey of patients with renal cell carcinoma (RCC) to capture real-world experiences has never been undertaken.

Among the manifestations of VHL are pancreatic neuroendocrine neoplasms (panNENs). In order to detect these lesions in a timely manner, patients are enrolled in a surveillance program, in accordance with the several existing VHL guidelines.
View Article and Find Full Text PDFPseudouridine (Ψ) is a ubiquitous RNA modification incorporated by pseudouridine synthase (Pus) enzymes into hundreds of noncoding and protein-coding RNA substrates. Here, we determined the contributions of substrate structure and protein sequence to binding and catalysis by pseudouridine synthase 7 (Pus7), one of the principal messenger RNA (mRNA) modifying enzymes. Pus7 is distinct among the eukaryotic Pus proteins because it modifies a wider variety of substrates and shares limited homology with other Pus family members.
