Damask roses () are widely used in cosmetics and pharmaceutics. Here, we established an in vitro suspension cell culture for calli derived from damask rose petals. We analyzed rose suspension cell transcriptomes obtained at two different time points by RNA sequencing to reveal transcriptional changes during rose suspension cell culture.

Article Synopsis
  • Encapsulating platinum nanoparticles in a carbon shell enhances their stability by preventing dissolution and clumping.* -
  • The study focused on how the carbon shell forms around the platinum core and identified the carbon-to-platinum precursor ratio as a key factor influencing the catalyst's properties.* -
  • Various analysis techniques were used to examine the catalysts' structures and test their electrochemical activity and stability, revealing a relationship between nitrogen-to-platinum ratios and their characteristics.*

The recent COVID-19 pandemic has been disrupting the daily lives of people across the world, causing a major concern for psychological well-being in children. This study aimed to examine (1) how life satisfaction and its potential predictors have been affected by the pandemic among school-aged children in Korea, and (2) which factors would predict their life satisfaction during the pandemic. We surveyed 166 fourth-graders in the Seoul metropolitan area to assess their psychological well-being and potentially related variables during the pandemic.

Article Synopsis
  • Camellia japonica L. is highlighted for its medicinal and cosmetic benefits, specifically its placenta extract (CJPE) which is tested for hair growth promotion and scalp health.
  • In vitro tests indicated that CJPE upregulates hair growth marker genes in human follicle dermal papilla cells, while in vivo trials showed improved scalp moisture and reduced issues like excess sebum and erythema among participants.
  • RNA-sequencing analysis revealed that CJPE influences key genes related to hair follicle biology and lipid metabolism, suggesting its potential as a therapeutic agent for hair growth and scalp treatment.

Edelweiss () in the family is a wildflower that grows in rocky limestone places. Here, we investigated the efficacy of edelweiss callus culture extract ( callus culture extract; LACCE) using multiple assays from to as well as transcriptome profiling. Several assay results showed the strong antioxidant activity of LACCE in response to UVB treatment.

The skin responds to environmental stressors by coordinated actions of neuropeptides and their receptors. An endogenous peptide for δ-opioid receptor (DOPr), Leu-enkephalin (L-ENK), is expressed in the skin and its expression is altered in pathological conditions. Although the importance of DOPr is rapidly gaining recognition, the molecular mechanisms underlying its effects on wound healing are largely undefined.

Aim: Protein L-isoaspartyl O-methyltransferase (PIMT) regulates cell adhesion in various cancer cell lines through activation of integrin αv and the PI3K pathway. The epithelial mesenchymal transition (EMT) enables epithelial cells to acquire the characteristics of mesenchymal cells, and to allow them to migrate for metastasis. Here, we examined the relationship between PIMT and EMT with attached or detached MDA-MB 231 cells.
