Coupled fixed point theorems of JS-G-contraction on G-metric spaces

Boletim da Sociedade Paranaense de Matemática, 2022
Jaradat has proven some fixed point results using JS-G-contraction on $G-$metric spaces. Choudhury et al. were derived coupled fixed point theorems for the $G-$metric spaces. The purpose of this paper is to prove some coupled fixed point theorems of JS-G-

Fixed point theorems for modified generalized F-contraction in G-metric spaces

Boletim da Sociedade Paranaense de Matemática, 2022
In this paper, we introduce new notions of generalized F-contractions of type(S) and type(M) in G-metric spaces. Some common fixed point theorems are proved using these notions. A suitable example is also provided to support our results.

Existence of fixed points in G-metric spaces

Boletim da Sociedade Paranaense de Matemática, 2022
In this manuscript, we provide some new results for the existence of fixed points for a certain contractive condition of Geraghty type in the setting of partially ordered $G$-metric space.

Some fixed point theorems on $\alpha$-$\beta$-$G$-complete $ G $-metric spaces

, 2021
In this manuscript, we initiate the concept of rectangular $\alpha$-$G$-admissible mappings with respect to $\beta$ and we consider related type contractions in the setting of $G$-metric spaces. We provide some fixed point results.

F-Modular b-Metric Spaces and Some Analogies of Classical Fixed Point Theorems

International Journal of Analysis and Applications
The main aim of this study is to provide a novel concept of F-modular b-metric spaces. Within this comprehensive framework, we establish three well-known fixed point theorems for self-maps.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

Molecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.
