Mechanotransduction is the interpretation of physical cues by cells through mechanosensation mechanisms that elegantly translate mechanical stimuli into biochemical signaling pathways. While mechanical stress and their resulting cellular responses occur in normal physiologic contexts, there are a variety of cancer-associated physical cues present in the tumor microenvironment that are pathological in breast cancer. Mechanistic in vitro data and in vivo evidence currently support three mechanical stressors as mechanical modifiers in breast cancer that will be the focus of this review: stiffness, interstitial fluid pressure, and solid stress. Increases in stiffness, interstitial fluid pressure, and solid stress are thought to promote malignant phenotypes in normal breast epithelial cells, as well as exacerbate malignant phenotypes in breast cancer cells.

This study presents T-1-NBAB, a new compound derived from the natural xanthine alkaloid theobromine, aimed at inhibiting VEGFR-2, a crucial protein in angiogenesis. T-1-NBAB's potential to interacts with and inhibit the VEGFR-2 was indicated using in silico techniques like molecular docking, MD simulations, MM-GBSA, PLIP, essential dynamics, and bi-dimensional projection experiments. DFT experiments was utilized also to study the structural and electrostatic properties of T-1-NBAB.

The maturation of the RNA cap involving guanosine N-7 methylation, catalyzed by the HsRNMT (RNA guanine-7 methyltransferase)-RAM (RNA guanine-N7 methyltransferase activating subunit) complex, is currently under investigation as a novel strategy to combat PIK3CA mutant breast cancer. However, the development of effective drugs is hindered by a limited understanding of the enzyme's mechanism and a lack of small molecule inhibitors. Following the elucidation of the HsRNMT-RAM molecular mechanism, we report the biophysical characterization of two small molecule hits.

Introduction: Outpatient cancer counseling centers (OCCs) are important social work facilities that provide support for cancer survivors who have psychosocial and sociolegal challenges. This paper explores clinical and sociodemographic characteristics, psychosocial burden as well as access routes of clients in OCCs seeking work-related counseling.

Methods: Between May 2022 and December 2023, data were collected in 19 OCCs, using questionnaires and documentation by counselors.

New Oral Selective Estrogen Receptor Degraders Redefine Management of Estrogen Receptor-Positive Breast Cancer.

Annu Rev Med

January 2025

Medical Oncology Department, Vall d'Hebron Barcelona Hospital Campus and Breast Cancer Group, Vall d'Hebron Institute of Oncology (VHIO), Barcelona, Spain; email:

Oral selective estrogen receptor degraders (SERDs) are pure estrogen receptor antagonists that have the potential to overcome common resistance mechanisms to endocrine therapy in estrogen receptor-positive breast cancer. There are currently five oral SERDs in published and ongoing clinical trials-elacestrant, camizestrant, giredestrant, imlunestrant, and amcenestrant-with more in development. They offer a reasonably well-tolerated oral therapy option with low discontinuation rates in studies.

The cysteine-rich epidermal growth factor ligand domain 2 protein (CRELD2) is associated with pathways that regulate epithelial-to-mesenchymal transition, a critical process driving cancer metastasis. This study aimed to determine the prognostic value of CRELD2 status on survival outcomes in triple-negative breast cancer (TNBC). Seventy patients were included in the study.
