The overexpression of NEURL1 also increased the apoptosis rate and cleaved caspase-3 protein expression in 5637 and RT-112 cells. As expected, the RING-deleted NEURL1 had no such effect. Moreover, NEURL1 overexpression facilitated the apoptosis of 5637/RT-112 cells under cisplatin conditions. NEURL1 promotes ubiquitination and proteasomal degradation of PDE9A. PDE9A protein expression was notably increased in bladder tumors from clinical specimens. Overexpressed NEURL1 inhibited PDE9A protein expression in both cell lines, whereas NEURL1 with the RING domain deletion did not. The addition of proteasome inhibitors MG-132 reversed the decrease in PDE9A expression by NEURL1 overexpression.

Fenofibrate, a lipid-regulating drug, has an unclear role in BBB function during stroke. This study investigates the effects of fenofibrate on BBB disruption and cerebrovascular endothelial cells induced by ischemia-reperfusion. Cerebral ischemia-reperfusion injury (CIRI) models were established using the middle cerebral artery occlusion (MCAO) method. Blood-brain barrier (BBB) integrity was assessed using Evans blue dye. The permeability of human brain microvascular endothelial cells (HBMVECs) was evaluated using fluorescein isothiocyanate (FITC)-dextran permeation assays and trans-endothelial electrical resistance (TEER) measurements. Additionally, real-time polymerase chain reaction (PCR), immunohistochemistry, enzyme-linked immunosorbent assay (ELISA), and Western blot analysis were performed. We found that the administration of fenofibrate improved brain endothelial dysfunction by reducing the expression of vascular cell adhesion molecule- 1 (VCAM- 1) and E-selectin in MCAO mice. Furthermore, fenofibrate restored the expression of the tight junction protein occludin in the cortices of MCAO mice. Notably, fenofibrate alleviated BBB dysfunction in MCAO mice. In vitro studies demonstrated that fenofibrate ameliorated endothelial monolayer permeability under oxygen-glucose deprivation/reoxygenation (OGD/R) conditions and inhibited the expression of VCAM- 1 and E-selectin in HBMVECs. Moreover, fenofibrate restored occludin expression following OGD/R. We identified a novel mechanism whereby fenofibrate suppressed the elevation of Egr- 1 induced by OGD/R; however, overexpression of Egr- 1 abrogated the protective effects of fenofibrate on the upregulation of VCAM- 1 and E-selectin and the downregulation of occludin induced by OGD/R. Furthermore, overexpression of early growth response- 1 (Egr- 1) negated the protective effects of fenofibrate on endothelial monolayer permeability and trans-endothelial electrical resistance (TEER).

Elevated temperature has been indicated as a major causing factor. Although ongoing research is focused on corals, sponges are an important benthic organism on coral reefs and are often overlooked. An accurate and standardized method is needed to determine the environmental limits and thresholds of sponges commonly found on coral reefs. We established an in vitro sponge cell model and evaluated the effect of elevated temperatures on primary cell cultures of five common Florida reef sponges-Agelas clathrodes, Aplysina fulva, Cliona varians, Geodia neptuni, and Xestospongia muta. Analysis of the results revealed that the impact of increased temperatures had no significant effect at the cellular level, but there are changes at the molecular level. Shifts in the sponges' transcriptomic profiles induced by increased temperatures, trigger processes related to signal transduction, apoptosis, and cell repair pathways. Further elevation of temperature corresponding to local extremes activated the immune response and programmed cell death. The results of the present study are based on both cellular and molecular data obtained from the in vitro cell model which highlight the minimal response of all five species to thermal stress, providing an insight into the mechanisms involved in the adaptive process. Furthermore, they suggest a resilience of these sponges to the current thermal extremes, but a combination of factors could still lead to a loss of sponges on reefs.

In this study, we selected three major wild-type mouse strains, CD1 (outbred; Jcl:ICR [ICR]), C57BL/6NJcl (inbred; B6), and BALB/cAJcl (inbred; C), which are widely used in laboratory experiments. Initially, we compared myotube fusion capabilities using satellite cell-derived myoblasts.

Next, we compared the myofiber-type compositions of muscle tissues and cultured myotubes among male mice from each of the three strains. Although each muscle tissue used for satellite cell isolation similarly expressed fast-twitch myofiber markers in all mouse strains, male ICR-derived myoblasts formed abundant amounts of slow-type myotubes. By contrast, myotubes from male B6 and C mice expressed substantial levels of fast-twitch myofiber markers. We also performed a comparative experiment in female ICR, B6, and C mouse strains, similar to the male mouse experiments. The myogenic differentiation potencies of myoblasts and myofiber-type compositions of myotubes in female mouse strains were similar.

Both cell lines required serum for growth and exhibited differential responses to basal media formulations. CAgill1PFR was sensitive to low temperatures (4 °C) but replicated at high temperatures (30 °C), whereas OTgill1PFR was sensitive to high temperatures but remained viable at low temperatures, mirroring the natural environment of their host species. Immunostaining revealed expression of epithelial cell markers cytokeratin and E-cadherin, alongside positivity for the mesenchymal cell marker, vimentin. CAgill1PFR was more sensitive to the environmental toxin 3,4 dichloroaniline than OTgill1PFR through measurements of metabolic activity, membrane integrity, and lysosomal function. Furthermore, CAgill1PFR produced less CYP1A activity, indicative of ongoing biotransformation processes, in response to beta-naphthoflavone than OTgill1PFR. These cell lines expand the toolbox of resources and emphasise the need for species-specific aquatic toxicology research.</p>","PeriodicalId":13340,"journal":{"name":"In Vitro Cellular & Developmental Biology.
