Psoriasis vulgaris is a serious noncommunicable disease, with no clear cause or cure. Expression of microRNA-31 (miR-31) is significantly increased in the cutaneous tissue of psoriasis vulgaris patients. Keratin 6 (Krt6) serves as a pivotal biomarker in the diagnostic and therapeutic approaches for psoriasis vulgaris. PSORI-CM01, a traditional Chinese medicine formulation comprising seven medicinal herbs, is employed in China for the therapeutic management of psoriasis vulgaris. However, its anti-psoriatic mechanism warrants further investigations. In this study, the underlying anti-psoriasis mechanism of PSORI-CM01dependent of miR-31 and Krt6 was explored.
, BALB/c mice were subjected to treatment with imiquimod (IMQ) to establish a psoriasis-like murine model. These psoriasis-like mice were then administered varying concentrations of PSORI-CM01. Following this, evaluations were performed on their Psoriasis Area and Severity Index (PASI) scores, epidermal thickness, and the expression levels of miR-31 and Krt6. HaCaT cells were subjected to treatment with interleukin-6 (IL-6) to create a psoriasis-like cellular model. Following this, the psoriasis-like keratinocytes were administered varying concentrations of PSORI-CM01, and the expression levels of miR-31 were quantified. In addition, these psoriasis-like keratinocytes were transfected with miR-31 mimics and subsequently treated with PSORI-CM01. The expression levels of Krt6 were then quantified and subjected to analysis.
, PSORI-CM01 significantly alleviated the clinical-like manifestations of erythema, scales, and thickening in psoriasis-like mice, and it also reduced the PASI scores; Different concentrations of PSORI-CM01 significantly decreased epidermal thickness and the expression of miR-31 and Krt6 in psoriasis-like mice in a dose-dependent manner. , PSORI-CM01 significantly inhibited the expression of miR-31 and Krt6 in psoriasis-like keratinocytes; However, the decreased Krt6 protein expression was restored by miR-31 mimics.
PSORI-CM01 may improve psoriasis-like lesions by inhibiting expression of Krt6 protein dependent of miR-31.
寻常型银屑病是一种严重的非传染性疾病,病因不明且无法治愈。寻常型银屑病患者皮肤组织中微小RNA-31(miR-31)的表达显著增加。角蛋白6(Krt6)是寻常型银屑病诊断和治疗方法中的关键生物标志物。PSORI-CM01是一种由七种草药组成的中药配方,在中国用于寻常型银屑病的治疗管理。然而,其抗银屑病机制有待进一步研究。在本研究中,探讨了PSORI-CM01依赖miR-31和Krt6的潜在抗银屑病机制。
将BALB/c小鼠用咪喹莫特(IMQ)处理以建立银屑病样小鼠模型。然后给这些银屑病样小鼠施用不同浓度的PSORI-CM01。在此之后,对它们的银屑病面积和严重程度指数(PASI)评分、表皮厚度以及miR-31和Krt6的表达水平进行评估。用人白细胞介素-6(IL-6)处理HaCaT细胞以建立银屑病样细胞模型。在此之后,给这些银屑病样角质形成细胞施用不同浓度的PSORI-CM01,并对miR-31的表达水平进行定量。此外,用miR-31模拟物转染这些银屑病样角质形成细胞,随后用PSORI-CM01处理。然后对Krt6的表达水平进行定量并进行分析。
PSORI-CM01显著减轻了银屑病样小鼠的红斑、鳞屑和增厚等临床样表现,并且还降低了PASI评分;不同浓度的PSORI-CM01以剂量依赖的方式显著降低了银屑病样小鼠的表皮厚度以及miR-31和Krt6的表达。PSORI-CM01显著抑制了银屑病样角质形成细胞中miR-31和Krt6的表达;然而,miR-31模拟物恢复了Krt6蛋白表达的降低。
PSORI-CM01可能通过抑制依赖miR-31的Krt6蛋白表达来改善银屑病样病变。
