Heliyon 2024; 10:e33051. [PMID: 39021977 PMCID: PMC11253279 DOI: 10.1016/j.heliyon.2024.e33051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Revised: 06/07/2024] [Accepted: 06/13/2024] [Indexed: 07/20/2024] Open
Abstract
YH0618, a medicinal and edible formulation, has demonstrated the potential to alleviate doxorubicin-induced alopecia in animal studies and clinical trials. However, the mechanisms underlying its therapeutic effects remain unexplored. The objective of this study was to ascertain possible therapeutic targets of YH0618 in the treatment of doxorubicin-induced alopecia. The assessment of hair loss was conducted through the measurement of the proportion of the affected area and the examination of skin histology. Isobaric tags for relative and absolute quantification (iTRAQ) in quantitative proteomics was employed to discern proteins that exhibited variable expressions. The major proteins associated with doxorubicin-induced alopecia were identified using gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. The interaction network of the differentially expressed proteins was constructed using the STRING database and the Python software. The study analyzed a total of 3894 proteins extracted from the skin tissue of mice. Doxorubicin treatment resulted in the upregulation of 18 distinct proteins, whereas one differential protein was found to be downregulated. The above effects were reinstated after the administration of the YH0618 therapy. The bioinformatic study revealed that the identified proteins exhibited enrichment in many biological processes, including staphylococcus aureus infection, estrogen signaling route, pyruvate metabolism, chemical carcinogenesis, and PPAR signaling pathway. The results of Western blot revealed that the levels of keratin 81 (Krt81), keratin 34 (Krt34), keratin 33a (Krt33a), and Sma and MAD-related protein 3 (Smad3) were upregulated in response to doxorubicin treatment, and were attenuated by the administration of YH0618. These four proteins are likely to correlate with DOX-induced alopecia and serve as promising therapeutic targets for YH0618. This work presents significant insights and empirical evidence for comprehending the process underlying chemotherapy-induced alopecia, paving the way for exploring innovative therapeutic or preventive strategies employing herbal items.

Local Flap Reconstruction of Burn Contractures in Extremities and Neck: A Nine-Year Experience with Long-Term Outcome Evaluation in Southwestern Iran. World J Plast Surg 2023; 12:47-56. [PMID: 38130383 PMCID: PMC10732291 DOI: 10.52547/wjps.12.2.47] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Accepted: 07/06/2023] [Indexed: 12/23/2023] Open
Abstract
Background Treating burn scar contractures remains challenging for reconstructive surgeons; no clear guidelines declare the optimal and most effective technique. We evaluated the efficacy of local flaps in treating patients with post-burn contractures. Methods This retrospective study included 243 patients with post-burn contractures referred to Taleghani Hospital (Khuzestan, southwest Iran) for local flap reconstruction from 2011 to 2020. Patients' demographic data, detailed descriptions of scars, surgical procedures, and flap outcomes were assessed. A plastic surgeon conducted all surgical procedures, the goals of which were to release the scar and cover the defect. Joint range of motion (ROM) (according to goniometric measurements), complications, need for second-stage surgery, and patient satisfaction were assessed. Results After scar release, 70.4% of joints were covered with a Z-plasty and similar local flaps, 26.1% with a Z-plasty plus skin grafts, and 3.5% with only skin grafts. The outcome after one year revealed a significant improvement in mean ROM (by 45.80% of the normal ROM; P< 0.001). The mean functional and aesthetic satisfaction scores were 9.45 and 7.61 out of 10, respectively. The complication rate was 10.82%: re-contracture occurred in 3.82%, flap tip necrosis in 1.27%, and partial flap necrosis in 0.31%. Conclusion Simple local flaps such as the Z-plasty are safe and effective in covering the joint following post-burn contracture release. Due to the feasibility, minimal need for facilities, steep learning curve, acceptable functional and aesthetic outcomes, and low complication rate, we strongly recommend the Z-plasty for reconstructing burn contractures, particularly in LMICs.
