PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Rapid Modulation of Aromatase Activity in the Vertebrate Brain

Journal of Experimental Neuroscience, 2013
Numerous steroid hormones, including 17β-estradiol (E2), activate rapid and transient cellular, physiological, and behavioral changes in addition to their well-described genomic effects. Aromatase is the key-limiting enzyme in the production of estrogens,

Cancer‐associated mutations in endometriosis reframe a benign disease through molecular oncology

Molecular Oncology, EarlyView.
This review aims to comprehensively analyse cancer‐associated somatic mutations (CAMs) present in endometriotic lesions, emphasizing their biological roles, spatial distribution and implications for translational applications in medicine. By contextualizing a benign state within a genomic framework, this analysis seeks to establish its value as a ...

Synthesis, Docking Studies and Biological Activity of New Benzimidazole- Triazolothiadiazine Derivatives as Aromatase Inhibitor

Molecules, 2020
In the last step of estrogen biosynthesis, aromatase enzyme catalyzes the conversion of androgens to estrogens. Aromatase inhibition is an important way to control estrogen-related diseases and estrogen levels.

A Multiple-Array SPRi Biosensor as a Tool for Detection of Gynecological–Oncological Diseases

Biosensors, 2023
Diagnostics based on the determination of biomarkers in body fluids will be more successful when several biomarkers are determined. A multiple-array SPRi biosensor for the simultaneous determination of CA125, HE4, CEA, IL-6 and aromatase has been ...

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

The breasts of Tutankhamun

Indian Journal of Endocrinology and Metabolism, 2012
Despite being an obscure pharaoh who ruled for a very short time, Tutankhamun, the boy king, has reigned popular consciousness since the discovery of his tomb in 1922. To endocrinologists, the depiction of the kings of the 18 th dynasty in an androgynous

Dual Role of Tamoxifen in Enhancing STING and CEACAM1 Expression to Prime a Favorable Tumor Microenvironment for Anti‐TIM3 Immunotherapy

Advanced Science, EarlyView.
Anti‐PD‐1/PD‐L1 blockade has revolutionized cancer immunotherapy, but is ineffective against endocrine‐treated (i.e., Tamoxifen), relapsed ER+ breast cancer (BC) patients. This study provides insight into the sub‐optimal response of ER+BCs to anti‐PD‐1/PD‐L1 blockade – highlighting the induction of STING and the CEACAM1/TIM3 axis after chronic ...

Correlating Changes in Follicular VLDL Binding and Follicular Aromatase Activity in the Ovulation Cycle of the Laying Hen

The Journal of Poultry Science, 2002
We examined whether very low-density lipoprotein receptors (VLDLR) on the oocyte membrane contributed to changes in VLDL uptake into the yolk by the ovarian follicle during the ovulation cycle of the laying hen.

Molecular Characterization of Aromatase [PDF]

Annals of the New York Academy of Sciences, 2009
Aromatase is an estrogen synthetase. Estrogens are female sex hormones involved in the development and growth of breast tumors. Elucidation of the structure‐function relationship of aromatase has been of significant interest since its inhibitors have shown great promise in fighting breast cancer.
