生物谷Bioon.com 訊 8月15日,,日本研究人員在英國(guó)《自然·遺傳學(xué)》(Nature Genetics)雜志網(wǎng)絡(luò)版上發(fā)表論文說(shuō),,他們發(fā)現(xiàn)了與瘢痕瘤有關(guān)的基因,。這一發(fā)現(xiàn)有可能為開(kāi)發(fā)徹底治療瘢痕瘤的方法開(kāi)辟道路,。
一些人在受傷或燙傷后,,受傷的皮膚會(huì)異常增殖,,乃至凸起后形成瘢痕瘤,,同時(shí)瘢痕瘤會(huì)讓人有疼痛和瘙癢的感覺(jué)。即使將瘢痕瘤清除掉,也很容易復(fù)發(fā),,難以根治,。
日本東京大學(xué)醫(yī)學(xué)研究所與理化學(xué)研究所研究人員對(duì)約820名瘢痕瘤患者進(jìn)行了研究。研究人員將他們的染色體組(全部遺傳信息)與約3200名普通人的染色體組進(jìn)行了比較和分析,。結(jié)果發(fā)現(xiàn),如果一個(gè)人“FOXL2”和“rs940187”兩個(gè)基因發(fā)生變異,,或者第一號(hào),、第三號(hào)染色體的特定范圍的堿基排列出現(xiàn)稍許差異,其瘢痕瘤發(fā)病風(fēng)險(xiǎn)就將比正常人高1.5至2倍,。如果上述現(xiàn)象同時(shí)存在,,其發(fā)病風(fēng)險(xiǎn)將比正常人高10倍。(生物谷Bioon.com)

Keloid is a dermal fibroproliferative growth that results from dysfunction of the wound healing processes. Through a multistage genome-wide association study using 824 individuals with keloid (cases) and 3,205 unaffected controls in the Japanese population, we identified significant associations of keloid with four SNP loci in three chromosomal regions: 1q41, 3q22.3–23 and 15q21.3. The most significant association with keloid was observed at rs873549 (combined P = 5.89 × 10?23, odds ratio (OR) = 1.77) on chromosome 1. Associations on chromosome 3 were observed at two separate linkage disequilibrium (LD) blocks: rs1511412 in the LD block including FOXL2 with P = 2.31 × 10?13 (OR = 1.87) and rs940187 in another LD block with P = 1.80 × 10?13 (OR = 1.98). Association of rs8032158 located in NEDD4 on chromosome 15 yielded P = 5.96 × 10?13 (OR = 1.51). Our findings provide new insights into the pathophysiology of keloid formation.
