The antipsychotic drug chlorpromazine enhances the cytotoxic effect of tamoxifen in tamoxifen-sensitive and tamoxifen-resistant human breast cancer cells

open access: yes, 2009
Tamoxifen resistance is a major clinical problem in the treatment of estrogen receptor α-positive breast tumors. It is, at present, unclear what exactly causes tamoxifen resistance.

Current Approaches to Support Patients to Withdraw From Image and Performance Enhancing Drugs

open access: yesClinical Endocrinology, EarlyView.
ABSTRACT Image and performance‐enhancing drugs (IPEDs) include agents such as androgens, growth hormone, and erythropoietin, which are used to enhance appearance and physical performance. Androgens, also known as anabolic‐androgenic steroids (AAS), are the most used IPEDs worldwide.

Olfactory Tuft Cells Are Critical to Basal Inflammation, Innate Immune Response to Viral Infection, and Modulation of Quiescent Stem Cell Activation, Proliferation and Differentiation

open access: yesCell Proliferation, EarlyView.
Olfactory tuft cells communicate with other mucosal cells in maintaining olfactory epithelial immunity and sensory function. Disruption of tuft cell signalling pathways causes a skewed immune response, leading to heightened inflammation and increased activation of the quiescent stem cells, which are further exacerbated by viral infection.

AFF4 Loss Compromises Osteogenesis of Orofacial Mesenchymal Stem Cells During Alveolar Bone Repair via AMPK‐Mediated Mitophagy

open access: yesCell Proliferation, EarlyView.
Compromised alveolar socket healing following tooth extraction upon Aff4 knockout is caused by suppressed osteogenic capacity of orofacial mesenchymal stem cells, which results from defective AMPK‐mediated mitophagy. ABSTRACT Repair of maxillofacial bone defects presents significant clinical challenges.

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems

open access: yesThe FEBS Journal, EarlyView.
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.

Non-coding RNA-mediated mechanisms underlying tamoxifen resistance in breast cancer

open access: yesDiscover Oncology
Tamoxifen remains a cornerstone therapy for estrogen receptor-positive (ER⁺) breast cancer; however, the emergence of drug resistance significantly limits its therapeutic success.

Epigenetic control of cellular plasticity in breast cancer progression

open access: yesThe FEBS Journal, EarlyView.
Cancer cells undergo cell state transitions, termed plasticity, driving cancer progression and dictating therapeutic response. We define breast cancer plasticity into four interconnected processes: (1) breast cancer stem cell fates, (2) epithelial‐to‐mesenchymal transition, (3) maintenance of luminal identity, and (4) acquisition of therapeutic ...

TMEM16A channel signalling microdomains in the regulation of vascular function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Overexpression of COL11A1 confers tamoxifen resistance in breast cancer

open access: yesnpj Breast Cancer
Breast cancer is the most commonly diagnosed malignancy and benefits from endocrine agents such as tamoxifen. However, the development of drug resistance in cancerous cells often leads to recurrence, thus limiting the therapeutic benefit.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...
