1. Dual mechanism β-amino acid polymers promoting cell adhesion
Qi Chen, Donghui Zhang, Wenjing Zhang, Haodong Zhang, Jingcheng Zou, Mingjiao Chen, Jin Li, Yuan Yuan, Runhui Liu Nat Commun. 2021 Jan 25;12(1):562. doi: 10.1038/s41467-020-20858-x.
Cell adhesion has tremendous impact on the function of culture platforms and implants. Cell-adhesive proteins and peptides have been extensively used for decades to promote cell adhesion, however, their application suffers from their easy enzymatic degradation, difficulty in large-scale preparation and expensiveness. To develop the next-generation cell-adhesive materials, we mimic the cell adhesion functions and mechanisms of RGD and KRSR peptides and design cell-adhesive cationic-hydrophobic amphiphilic β-amino acid polymers that are stable upon proteolysis and easily prepared in large scale at low cost. The optimal polymer strongly promotes cell adhesion, using preosteoblast cell as a model, by following dual mechanisms that are independent of sequence and chirality of the statistic copolymer. Our strategy opens avenues in designing the next-generation cell-adhesive materials and may guide future studies and applications.
2. Role of opiorphin genes in prostate cancer growth and progression
Amarnath Mukherjee, Augene Park, Li Wang, Kelvin P Davies Future Oncol. 2021 Jun;17(17):2209-2223. doi: 10.2217/fon-2020-1299. Epub 2021 Feb 17.
Background: We describe the first studies investigating a role for opiorphin genes (PROL1, SMR3A and SMR3B) in prostate cancer (PrCa). Materials & methods: Databases and PrCa tissue arrays were screened for opiorphin expression. Xenografted tumor growth of human PrCa cells overexpressing PROL1 was compared with controls in nude mice. Modulated gene expression by overexpression of PROL1 was determined by RNA sequencing. Results: PrCa is associated with overexpression of opiorphin genes. Xenografted androgen-sensitive PrCa cells overexpressing PROL1 developed into tumors in castrated male mice (in contrast to parental cells). PROL1 overexpression modulates expression of genes in angiogenesis, steroid and hypoxic response pathways. Conclusions: Opiorphins promote the development of androgen-insensitive PrCa and activate pathways that potentially overcome the hypoxic barrier generated during tumor growth.
3. Relationship between saliva opiorphin levels, pain threshold, and cutting number in adolescents with non suicidal self injury
Erdal Görkem Gavcar, Bürge Kabukçu Başay, Esin Avci, Ömer Başay J Psychiatr Res. 2022 Jul;151:611-618. doi: 10.1016/j.jpsychires.2022.05.030. Epub 2022 May 24.
Various opinions have been suggested regarding non suicidal self-injury (NSSI) and pain relationship. Opiorphin is a recently found peptide that inhibits enkephaline-catabolizing enzymes. Analgesia caused by opiorphine has been demonstrated in animal experiments. No studies have examined the relationship between opiorphin and pain sensation until today. We aimed to investigate opiorphine and pain threshold among self-injuring adolescents. Adolescents aged 14-18 years were included in the study. The NSSI group consisted of 37 adolescents diagnosed with NSSI according to DSM-V Section 3, and the non-NSSI group consisted of 36 adolescents without any psychiatric disorder. We measured pain threshold with a pressure sensitive algometer device and analyzed saliva opiorphin levels by ELISA method. Mediation analysis was performed using Process Macro developed by Hayes. NSSI group had statistically significantly higher pain threshold and opiorphin levels than the non-NSSI group. There was a positive correlation between pain threshold values and opiorphin levels in the NSSI group. Also, a positive correlation between opiorphin levels and total cutting episode number was found. We searched for a probable relationship of pain threshold with episode number of each type of NSSI act. Accordingly, a positive correlation with two major act and a negative correlation with two minor act was shown. The opiorphine was found to be a mediator variable in the relationship between the pain threshold and the cutting number. The relationship between opiorphin, pain threshold and cutting number and their mediating effects with each other may highlight the pain-based biological origins of NSSI.
