Expression of Ca(2+) Transport Genes in Platelets and Endothelial Cells in Hypertension.

Hypertension (Dallas, Tex. : 1979)

Mountian, Baba-Aïssa F, Jonas JC, Humbert De Smedt, Wuytack F, Parys JB.
PMID: 11208768
Hypertension. 2001 Jan;37(1):135-141. doi: 10.1161/01.hyp.37.1.135.

-Altered Ca(2+) handling is observed in different cells in essential hypertension. We investigated the expression of sarco(endo)plasmic reticulum Ca(2+)-ATPase (SERCA) and inositol 1,4,5-trisphosphate receptor (IP(3)R) isoforms in platelets and aortic endothelial cells (EC) isolated from spontaneously hypertensive (SHR) and...

STIM1 as a key regulator for Ca2+ homeostasis in skeletal-muscle development and function.

Skeletal muscle

Kiviluoto S, Decuypere JP, De Smedt H, Missiaen L, Parys JB, Bultynck G.
PMID: 21798093
Skelet Muscle. 2011 Apr 04;1(1):16. doi: 10.1186/2044-5040-1-16.

Stromal interaction molecules (STIM) were identified as the endoplasmic-reticulum (ER) Ca2+ sensor controlling store-operated Ca2+ entry (SOCE) and Ca2+-release-activated Ca2+ (CRAC) channels in non-excitable cells. STIM proteins target Orai1-3, tetrameric Ca2+-permeable channels in the plasma membrane. Structure-function analysis revealed...

Unraveling the role of polycystin-2/inositol 1,4,5-trisphosphate receptor interaction in Ca signaling.

Communicative & integrative biology

Sammels E, Devogelaere B, Mekahli D, Bultynck G, Missiaen L, Parys JB, De Smedt H.
PMID: 21331231
Commun Integr Biol. 2010 Nov;3(6):530-2. doi: 10.4161/cib.3.6.12751. Epub 2010 Nov 01.

Autosomal dominant polycystic kidney disease (ADPKD) arises as a consequence of mutations of the genes PKD1 and PKD2, encoding respectively the integral membrane proteins polycystin-1 and polycystin-2 (TRPP2), resulting in a disturbance in intracellular Ca(2+) signaling. Previously we investigated...

IP(3) Receptors, Mitochondria, and Ca Signaling: Implications for Aging.

Journal of aging research

Decuypere JP, Monaco G, Missiaen L, De Smedt H, Parys JB, Bultynck G.
PMID: 21423550
J Aging Res. 2011 Mar 08;2011:920178. doi: 10.4061/2011/920178.

The tight interplay between endoplasmic-reticulum-(ER-) and mitochondria-mediated Ca(2+) signaling is a key determinant of cellular health and cellular fate through the control of apoptosis and autophagy. Proteins that prevent or promote apoptosis and autophagy can affect intracellular Ca(2+) dynamics...

Reciprocal sensitivity of diffuse large B-cell lymphoma cells to Bcl-2 inhibitors BIRD-2 versus venetoclax.

Oncotarget

Vervloessem T, Akl H, Tousseyn T, De Smedt H, Parys JB, Bultynck G.
PMID: 29340082
Oncotarget. 2017 Dec 04;8(67):111656-111671. doi: 10.18632/oncotarget.22898. eCollection 2017 Dec 19.

Bcl-2 is often upregulated in cancers to neutralize the BH3-only protein Bim at the mitochondria. BH3 mimetics (e.g. ABT-199 (venetoclax)) kill cancer cells by targeting Bcl-2's hydrophobic cleft and disrupting Bcl-2/Bim complexes. Some cancers with elevated Bcl-2 display poor...

PKD2/polycystin-2 induces autophagy by forming a complex with BECN1.

Autophagy

Peña-Oyarzun D, Rodriguez-Peña M, Burgos-Bravo F, Vergara A, Kretschmar C, Sotomayor-Flores C, Ramirez-Sarmiento CA, De Smedt H, Reyes M, Perez W, Torres VA, Morselli E, Altamirano F, Wilson CAM, Hill JA, Lavandero S, Criollo A.
PMID: 32543276
Autophagy. 2021 Jul;17(7):1714-1728. doi: 10.1080/15548627.2020.1782035. Epub 2020 Jun 30.

Macroautophagy/autophagy is an intracellular process involved in the breakdown of macromolecules and organelles. Recent studies have shown that PKD2/PC2/TRPP2 (polycystin 2, transient receptor potential cation channel), a nonselective cation channel permeable to Ca
