Estrogen Signaling in ERα-Negative Breast Cancer: ERβ and GPER

Frontiers in Endocrinology, 2019
Estrogen receptors are important regulators of the growth of breast tumors. Three different receptors for estrogens have been identified in breast tumors, two nuclear receptors, ERα and ERβ, and a G-protein coupled estrogen receptor 1 (GPER) that ...

Mutational and secondary structural analysis of the basolateral sorting signal of the polymeric immunoglobulin receptor. [PDF]

, 1993
The 17-juxtamembrane cytoplasmic residues of the polymeric immunoglobulin receptor contain an autonomous basolateral targeting signal that does not mediate rapid endocytosis (Casanova, J. E., G. Apodaca, and K. E. Mostov. Cell. 66:65-75).

VEGF (Vascular Endothelial Growth Factor) Induces NRP1 (Neuropilin-1) Cleavage via ADAMs (a Disintegrin and Metalloproteinase) 9 and 10 to Generate Novel Carboxy- Terminal NRP1 Fragments That Regulate Angiogenic Signaling [PDF]

, 2018
OBJECTIVE: NRP1(neuropilin-1) acts as a coreceptor for VEGF (vascular endothelial growth factor) with an essential role in angiogenesis. Recent findings suggest that posttranslational proteolytic cleavage of VEGF receptors may be an important mechanism

Quantitative Estimates of Cytoplasmic and Nuclear Oestrogen Receptors in Chick Oviduct [PDF]

European Journal of Biochemistry, 1976
[3H]Oestradiol exchange techniques were developed for the determination of specific cestrogen receptor site concentrations in the cytoplasm and nuclei of chick oviduct cells. Non‐labelled receptor‐bound oestrogens were exchanged with [3H]oestradiol during a 24‐h incubation at 20 °C. 2 h at 30 °C or 45 min at 37 °C.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

All Hands on Deck—The Role of Chloroplasts, Endoplasmic Reticulum, and the Nucleus in Driving Plant Innate Immunity

Molecular Plant-Microbe Interactions, 2010
Plant innate immunity is mediated by cell membrane and intracellular immune receptors that function in distinct and overlapping cell-signaling pathways to activate defense responses.

Molecular Genetics of Intracranial Meningiomas with Emphasis on Canonical Wnt Signalling. [PDF]

, 2016
Research over the last decade recognized the importance of novel molecular pathways in pathogenesis of intracranial meningiomas. In this review, we focus on human brain tumours meningiomas and the involvement of Wnt signalling pathway genes and proteins ...

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Androgen Induces a Switch from Cytoplasmic Retention to Nuclear Import of the Androgen Receptor [PDF]

Molecular and Cellular Biology, 2013
The androgen receptor (AR) has critical functions as a transcription factor in both normal and cancer cells, but the specific mechanisms that regulate its nuclear localization are not well defined. We found that an AR mutation commonly reported in prostate cancer generates an androgen-independent gain of function for nuclear import.
