Special Issue Information

Dear Colleagues,

The skin represents the most exposed barrier of organisms, and, as such, has been the subject of intensive research focused on both neoplastic and inflammatory conditions. Recently, personalized therapies have gained attention not only on the scientific level, but also on the clinical level. These therapies have revolutionized oncology, with melanoma being the most explored cutaneous disease, by the use of new, cutting-edge treatments, including immunotherapies and targeted therapies. Personalized therapies are not limited to oncologic diseases, as much interest has been put into detecting and applying biological agents in several inflammatory disorders. As a superficial barrier, the skin has also received notable interest regarding its drug administration capacities. Moreover, research even has to consider the essential role of the skin in increasingly valued aesthetics, not only as a primary need of patients but also in avoiding side effects.

This proposed Special Issue aims to collect the most recent insights into clinical and translational research regarding melanoma, nonmelanoma skin neoplasms, and inflammatory cutaneous conditions. The scope of the research includes studies with novel diagnostic or therapeutic approaches that can result in more personalized and efficient cutaneous medicine, including molecular/cellular mechanisms, detection, stratification, surveillance, care management, or treatment of cutaneous diseases.

The pathophysiology of atopic dermatitis (AD) is complex, multifactorial, and not fully understood. Genes encoding collagens, the most abundant proteins in the extracellular matrix (ECM), may play a potential role in the pathogenesis of AD. Our study aimed to estimate the associations between Col3A1/rs1800255, Col6A5 /29rs12488457, and Col8A1/rs13081855 polymorphisms and the occurrence, course, and features of AD in the Polish population. Blood samples were collected from 157 patients with AD and 111 healthy volunteers. The genotype distribution of the investigated collagens genes did not differ significantly between the AD and control subjects (p > 0.05). The AA genotype of Col3A1/rs1800255 was significantly associated with the occurrence of mild SCORAD (OR = 0.16; 95% Cl: 0.03–0.78; p = 0.02) and mild pruritus (OR = 18.5; 95% Cl: 3.48–98.40; p = 0.0006), while the GG genotype was significantly associated with severe SCORAD (OR = 6.6; 95% Cl: 1.23–32.35; p = 0.03). Regarding Col6A5/29rs12488457 polymorphism, the average SCORAD score was significantly lower in the group of patients with genotype AA than in patients with the AC genotype (39.8 vs. 53.4; p = 0.04). Nevertheless, both average SCORAD scores were high, and represent the moderate and severe grades of the diseases, respectively. The single nucleotide polymorphisms (SNPs) of COL3A1/ rs1800255 and Col6A5/29rs12488457 seem to be associated with AD courses and symptoms, suggesting new disease biomarkers. The modulation of collagens, the major component of the ECM, may serve as a therapeutic target of AD in the future. Full article

N6-methyladenosine (m6A) modulates RNA metabolism and functions in cell differentiation, tissue development, and immune response. After acute burns, skin wounds are highly susceptible to infection and poor healing. However, our understanding of the effect of burn injuries on m6A methylation and their potential mechanism is still limited. Human m6A-mRNA&lncRNA Epitranscriptomic microarray was used to obtain comprehensive mRNA and lncRNA transcriptome m6A profiling and gene expression patterns after burn injuries in human skin tissue. Bioinformatic and functional analyses were conducted to find molecular functions. Microarray profiling showed that 65 mRNAs and 39 lncRNAs were significantly hypermethylated; 5492 mRNAs and 754 lncRNAs were significantly hypomethylated. Notably, 3989 hypomethylated mRNAs were down-expressed and inhibited many wound healing biological processes and pathways including in the protein catabolic process and supramolecular fiber organization pathway; 39 hypermethylated mRNAs were up-expressed and influenced the cell surface receptor signaling pathway and inflammatory response. Moreover, we validated that m6A regulators (METTL14, METTL16, ALKBH5, FMR1, and HNRNPC) were significantly downregulated after burn injury which may be responsible for the alteration of m6A modification and gene expression. In summary, we found that homeostasis in the skin was disrupted and m6A modification may be a potential mechanism affecting trauma infection and wound healing. Full article
