Article Title: Involvement of calcium-sensing receptors in hypoxia-induced vascular remodeling and pulmonary hypertension by promoting phenotypic modulation of small pulmonary arteries.
Article Snippet: Phenotype modulation of pulmonary artery smooth muscle cells (PASMCs) plays an important role during hypoxia-induced vascular remodeling and pulmonary hypertension (PAH).. We had previously shown that calcium-sensing receptor (CaSR) is expressed in rat PASMCs.. However, little is known about the role of CaSR in phenotypic modulation of PASMCs in hypoxia-induced PAH as well as the underlying mechanisms.

Experimental design. Femoral head articular cartilage samples from 16 mice were harvested in pairs and each pair was placed in one well of a 96-well plate with serum-free Opti-MEM supplemented with 1% penicillin-streptomycin, maintained under standard normoxic conditions (21% O 2 , 5% CO 2 , 37°C). After three days, half of the cultures were transferred to a hypoxia incubator (3% O 2 ). Following 24 hours of normoxic or hypoxic incubation, cultures were treated with recombinant human TIMP-3 (100 nM; 2.6 µg/ml) or vehicle for 20 hours, and RNA was extracted for RNA sequencing (n = 4 per group). Group labels: NC, normoxia control; NT, normoxia TIMP-3; HC, hypoxia control; HT, hypoxia TIMP-3.

The Y191C variant inhibited the interaction between TIMP3 and MMP proteins. ( A and B ) The Y191C mutation increases FLAG-TIMP3 complex formation, selectively enhancing interaction with MMP9 proteolytic fragments (45~55 kDa) while reducing MMP2 binding. ( C – E ) Following LPS administration, MMP2 expression levels in the empty vector control group remained comparable to those in the normal control group. However, in the MT group, MMP2 expression was significantly elevated compared to the empty vector group ( P < 0.0001, 1.84 ± 0.21-fold) and showed a modest increase compared to the WT control group ( P= 0.0889, 1.15 ± 0.13-fold). Additionally, MMP9 expression in the MT group was markedly higher than in the empty vector group after LPS treatment ( P < 0.0172, 2.12 ± 0.41-fold). ( F ) IF staining revealed nuclear localization of MMP2 in ARPE-19 cells of the WT group, whereas in the MT group, MMP2 expression extended into the cytoplasm of ARPE-19 cells. n=3/group. “n” refers to the number of independent biological replicates.
