USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

open access: yesMolecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

On the semicontinuity of curvatures

open access: yesCommentarii Mathematici Helvetici, 1992
For a convex body \(K\) in \(\mathbb{R}^ n\) with a boundary of class \(C^ 2\) and positive curvatures and for \(\alpha\in\mathbb{R}\backslash\{0\}\) and \(j=1,\ldots,n-1\), let \[ \psi^ \alpha_ j(K)=\left\{{1\over\omega_ n}\int_{S^{n-1}}s_ j(K,u)^ \alpha d\omega(u)\right\}^{1/\alpha}, \] where \(s_ j(K,u)\) is the normalized \(j\)-th elementary ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Darboux Frame of Pancake Curve in Euclidean 3-Space

open access: yesCumhuriyet Science Journal
In this paper, we focus on a rare curve, “The pancake curve” which was named by Robert Ferréol. We investigate the Darboux frame of the curve, and we calculate the curvatures: geodesic curvature, normal curvature, and geodesic torsion.

Beltrami-Meusnier formulas of generalized semi ruled surfaces in semi Euclidean space

open access: yesKuwait Journal of Science, 2014
In this paper, we study the sectional curvatures of the generalized semi ruled surfaces in semi Euclidean space   The first fundamental form and the metric coefficients of the generalized semi ruled surfaces are calculated and in these regards ...

MOTION OF CURVES USING QUASI FRAME [PDF]

open access: yesAssiut University Journal of Multidisciplinary Scientific Research, 2018
In this paper, evolution of space curves using quasi frame are considered. We derive a pair of coupled partialdifferential equations that governing the time evolution for the quasi curvatures of the evolving curve.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

On Gauss-Bonnet Curvatures

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
The $(2k)$-th Gauss-Bonnet curvature is a generalization to higher dimensions of the $(2k)$-dimensional Gauss-Bonnet integrand, it coincides with the usual scalar curvature for $k = 1$.
