Published in 2017 at "Pharmacological Research"

DOI: 10.1016/j.phrs.2016.12.007

Abstract: ABSTRACT The mammary epithelium is highly responsive to hormonal and non‐hormonal signalling cues for physiological growth, function and tissue remodelling. Whilst steroid hormones freely diffuse across the cell membrane to bind to intracellular hormone receptors,… read more here.

Published in 2020 at "NPJ Breast Cancer"

DOI: 10.1038/s41523-020-00184-7

Abstract: Terminal duct lobular units (TDLUs) are the predominant anatomical structures where breast cancers originate. Having lesser degrees of age-related TDLU involution, measured as higher TDLUs counts or more epithelial TDLU substructures (acini), is related to… read more here.

Published in 2021 at "Communications in Algebra"

DOI: 10.1080/00927872.2021.1955899

Abstract: Let $F\langle X, \ast \rangle$ be the free associative algebra with involution $\ast$ over a field $F$ of characteristic zero. We study the asymptotic behavior of the sequence of $\ast$-codimensions of the T-$\ast$-ideal $\Gamma_{M+1,L+1}^\ast$ of… read more here.

Published in 2022 at "Journal of the National Cancer Institute"

DOI: 10.1093/jnci/djac063

Abstract: Reduced age-related terminal duct lobular unit (TDLU) involution has been linked to increased breast cancer risk and triple-negative breast cancer (TNBC). Associations of TDLU involution levels with race and ethnicity remain incompletely explored. Herein, we… read more here.
