概括

在 keloid 痕中,循环 RNA (circRNA) 的表观遗传调节尚不清楚. 这项研究确定circ_064002是 keloid 纤维细胞中纤维素-1 (FN1) 的关键调节剂,影响细胞功能.

科学领域:

* 分子生物学和表观遗传学.
*生物信息学和计算生物学.
*皮肤病学和伤口愈合研究.

背景情况:

* 非编码RNAs (ncRNAs) 的表观遗传修饰对于纤维细胞激活和化形成的分化至关重要.
*圆形RNAs (circRNAs) 在 keloid 病原发生中的特定作用仍然在很大程度上是未知的.
* 了解circRNA机制可以为 keloid 发育提供新的见解.

研究的目的:

* 调查在易患质的个体中,在伤口愈合过程中差异表达的circRNAs,microRNAs (miRNAs) 和信使RNAs (mRNAs) 之间的相互作用.
* 构建一个竞争的内源RNA (ceRNA) 网络以阐明 keloid 病理生理学.
* 确定特定的circRNA及其在化物衍生纤维细胞中的调节作用.

主要方法:

*使用生物信息学方法分析来自GSE113621数据库的基因表达特征.
*识别和构建差异表达的circRNA (DEcircRNA) 和ceRNA网络.
* 在 keloid 组织中预测的 DEcircRNAs 的验证,以及在 keloid 衍生纤维细胞 (KFs) 中的功能测定.

主要成果:

*鉴定了29个DEcircRNA,并从基因表达数据中构建了14个ceRNA网络.
*阐明了涉及circ_064002,miR-30a/b-5p和纤维蛋白-1 (FN1) 的特定ceRNA网络.
*KFs中的circ_064002显著下调的FN1表达和受损的细胞功能 (活力,迁移,入侵,修复) 的抑制.

结论:

* 这项研究揭示了通过ceRNA网络在 keloid 纤维细胞中circ_064002 的表观遗传调节机制.
*Circ_064002通过调节FN1表达和纤维细胞功能,在 keloid 发育中发挥关键作用.

Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
