GATA-4 is an important transcription factor involved in several developmental processes of the heart, such as cardiac myocyte proliferation, differentiation and survival. The precise mechanisms underlying the regulation of GATA-4 remain unclear, this is especially true for the mechanisms that mediate the post-transcriptional regulation of GATA-4. Here, we demonstrate that miR-200b, a member of the miR-200 family, is a critical regulator of GATA-4. Overexpression of miR-200b leads to the downregulation of GATA-4 mRNA and a decrease in GATA-4 protein levels. Moreover, miR-200b not only inhibits cell growth and differentiation but also reverses the growth response mediated by GATA-4, whereas depletion of miR-200b leads to a slight reversal of the anti-growth response achieved by knocking down endogenous GATA-4. More importantly, the cell cycle-associated gene cyclin D1, which is a downstream target of GATA-4, is also regulated by miR-200b. Thus, miR-200b targets GATA-4 to downregulate the expression of cyclin D1 and myosin heavy chain (MHC), thereby regulating cell growth and differentiation.
Operative intervention is a better treatment choice for patients with post-operative solitary liver metastasis from ESCC, especially for patients with a DFI lasting >12 months. Patients selected for hepatic resection should be considered on an individual basis through a multidisciplinary team of specialists.
Background
With the pandemic dissemination of COVID‐19, attitude and sentiment surrounding facial rejuvenation have evolved rapidly.
Aims
The purpose of this study was to understanding the impact of pandemic on the attitude of people toward facial skin rejuvenation.
Methods
Twitter data related to facial rejuvenation were collected from January 1, 2020, to April 30, 2020. Sentiment analysis, frequency analysis, and word cloud were performed to analyze the data. Statistical analysis included two‐tailed t tests and chi‐square tests.
Results
In the post‐declaration, the number of tweets about facial rejuvenation increased significantly, and the search volume in Google Trends decreased. Negative public emotions increased, but positive emotions still dominate. The words frequency of “discounts” and “purchase” decreased. The dominant words in word cloud were “Botox,” “facelift,” “hyaluronic,” and “skin.”
Conclusion
The public has a positive attitude toward facial rejuvenation during the pandemic. In particular, minimally invasive procedures dominate the mainstream, such as “Botox,” “Hyaluronic acid,” and “PRP.” The practitioners could understand the change of the public interest in facial rejuvenation in time and decide what to focus on.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
