Predictive and prognostic biomarkers of Bacillus Calmette‐Guérin therapy failure in bladder cancer patients: A systematic review

open access: yesMolecular Oncology, EarlyView.
High‐risk bladder cancer is typically treated with Bacillus Calmette‐Guérin (BCG), but 30–40% of patients relapse. No FDA‐ or CE‐approved biomarkers currently predict or prognosticate BCG failure. We systematically reviewed the literature and identified 72 eligible studies, revealing several promising biomarkers associated with BCG treatment response ...

NAPRT loss promotes lung tumor initiation and growth through AKT signaling independently of NAD+ biosynthesis

open access: yesMolecular Oncology, EarlyView.
Loss of NAPRT promotes lung tumor initiation and growth through a noncanonical mechanism, independent of its role in NAD+ biosynthesis. Mechanistically, NAPRT depletion activates the mTORC2‐driven AKT/β‐catenin signaling axis to enhance clonogenic and invasive phenotypes. Furthermore, lung‐specific Naprt deletion significantly increases tumor burden in

Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

open access: yesMolecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Revisiting graphical rectangular b-metric spaces

Asian-European Journal of Mathematics, 2021
Very recently, the notion of graphical rectangular [Formula: see text]-metric spaces has been introduced, where the weight of the symmetric edges endowing the directed graph is defined in terms of the underlying metric. Due to its intimate relationship with the directed graphs, such spaces have a wide range of applications in science and engineering ...

On completeness in strong partial b-metric spaces, strong b-metric spaces and the 0-Cauchy completions

Topology and its Applications, 2020
In this paper, the authors introduce the notion of strong partial \(b\)-metric space and establish a number of completion results over such structures. The following are the main results of this exposition. \textbf{Theorem 1.} Every strong partial \(b\)-metric space \((X,\alpha,\sigma)\) admits a \(0\)-Cauchy completion \((X^*,\alpha,\sigma ...

Principles for the Design of Online A/B Metrics

Proceedings of the 39th International ACM SIGIR conference on Research and Development in Information Retrieval, 2016
In this paper, we describe principles for designing metrics in the context of A/B experiments. We share some issues that comes up in designing such experiments and provide solutions to avoid such pitfalls.

b-Metric Spaces

2014
In 1993 another axiom for semimetric spaces, which is weaker than the triangle inequality, was put forth by Czerwik [58] with a view of generalizing the Banach contraction mapping theorem. This same relaxation of the triangle inequality is also discussed in Fagin et al. [79], who call this new distance measure nonlinear elastic matching (NEM).

Remarks on b-Metric and metric-preserving functions

Mathematica Slovaca, 2018
Abstract We introduce new classes of functions related to metric-preserving functions and b-metrics. We investigate their properties and compare them to those of metric-preserving functions.
