To assess the effect of Cannabidiol (CBD) on the angiogenesis and stemness of breast cancer cells as well as proliferation. Methods: mRNA level and the amount of protein of vascular endothelial growth factor (VEGF) were determined by qRT-PCR and ELISA. The angiogenic potential of breast cancer cells under hypoxic conditions was identified by the HUVEC tube formation assay. The degradation of HIF-1α by CBD and the Src/von Hippel-Lindau tumor suppressor protein (VHL) interaction were assessed by a co-immunoprecipitation assay and Western blotting. To identify the stemness of mamospheres, they were evaluated by the sphere-forming assay and flow cytometry. Results: CBD can suppress angiogenesis and stem cell-like properties of breast cancer through Src/VHL/HIF-1α signaling. CBD may potentially be utilized in the treatment of refractory or recurrent breast cancer.

One of the main challenges in breast cancer management is health system literacy to provide optimal and timely diagnosis and treatments within complex and multidisciplinary health system environments. Digitalised patient navigation programs have been developed and found to be helpful in high- and low-resource settings, but gaps remain in finding cost-effective navigation in the public sector in Malaysia, where resources are scarce and unstable. Hence, we set out to develop a virtual patient navigation application for breast cancer patients to enhance knowledge about cancer diagnosis and treatments and provide a tracking mechanism to ensure quality care.

Introduction: Detection of mutations in primary tumors and liquid biopsy samples is of increasing importance for treatment decisions and therapy resistance in many types of cancer. The aim of the present study was to directly compare the efficacy of a relatively inexpensive ultrasensitive real-time PCR with the well-established and highly sensitive technology of ddPCR for the detection of the three most common hotspot mutations of , in exons 9 and 20, that are all of clinical importance in various types of cancer.
Patients And Methods: We analyzed 42 gDNAs from primary tumors (FFPEs), 29 plasma-cfDNA samples, and 29 paired CTC-derived gDNAs, all from patients with ER+ metastatic breast cancer, and plasma from 10 healthy donors.

Carbon dot (CD)-based theranostics offers a promising approach for breast cancer (BC) treatment, integrating ultra-localized chemo-photothermal effects to address chemoresistance and enhance therapeutic control. Herein, the development of a targeted theranostic nanosystem for the chemo-phototherapy of breast cancer is described. Fluorescent and biocompatible CDs were passivated with 1,2-bis(3-aminopropylamino)ethane (bAPAE) and decorated with the targeting agent folic acid (FA) through conjugation with a PEG spacer.

We and others reported that G inhibitor FR900358 (FR) can inhibit both and G - and, surprisingly, G -mediated intracellular Ca mobilization. Thus, the G -G -PLCβ-Ca signaling axis depends entirely on the presence of active G , which reasonably explained FR-inhibited G -induced Ca release.
