Early identification of participants at risk of cognitive decline: An online tool for patient prediction of cognitive decline.

Background: The success of therapeutic options for treatment of Alzheimer’s disease (AD) and the growing emphasis for such treatment to commence in the pre‐clinical phase makes it necessary to have robust empirical models of clinical disease progression to understand findings from clinical trials, allow clinicians to evaluate effects of new drugs, and to select individuals for future trials. Such models have been developed from relatively small samples, with incomplete data/substantial loss to follow‐up. The ADOPIC consortium provides the largest complete AD natural history sample to date.

Pharmacological Vitamin C-induced high HO generation mediates apoptotic cell death by caspase 3/7 activation in breast cancer tumor spheroids.

Background: Pharmacological vitamin C (Vit-C), or high-dose Vit-C has recently gained attention as a potential cancer therapeutic. However, the anticancer activity of Vit-C has not been investigated in realistic 3D models of human cancers, especially with respect to breast cancer (BC), and its potential benefits remain under debate. Herein, we investigate the activity and mechanism of action of pharmacological Vit-C on two BC tumor spheroids.

Exploring the role of splicing in TP53 variant pathogenicity through predictions and minigene assays.

Background: TP53 variant classification benefits from the availability of large-scale functional data for missense variants generated using cDNA-based assays. However, absence of comprehensive splicing assay data for TP53 confounds the classification of the subset of predicted missense and synonymous variants that are also predicted to alter splicing. Our study aimed to generate and apply splicing assay data for a prioritised group of 59 TP53 predicted missense or synonymous variants that are also predicted to affect splicing by either SpliceAI or MaxEntScan.
