HK-2 cells with N-acetyl cysteine, suppressed Bis induction. Furthermore, HSF1 silencing attenuated Bis expression that was induced by H2O2, accompanied by increase in reactive oxygen species (ROS) accumulation. Using a series of deletion constructs of the bis gene promoter, two putative heat shock elements located in the proximal region of the bis gene promoter were found to be essential for the constitutive expression is as well as the inducible expression of Bis. Taken together, our results... -

거의 이루어지지 않고 있다. 여기서 우리 연구진은 자연에서 분리된 Saccharomyces cerevisiae KNU5377 균주를 이용하여 random spore analysis를 통해 MATa 및 $MAT{alpha}$ 타입의 각각의 haploid cell을 분리 후 이미 보고된 KanMX module를 가지고 round PCR기법에 의한 short flanking homology 기법을 이용하여 전사조절인자인 HSF1 유전자가 치환된 변이주를 구축할 수 있었다. 덧붙여, 모든 유전자에 이 기법을 적용할 수는 없다는 것을 확인하였다. 앞으로 이 변이주를 통해 기능 유전체학적인 측면에서 이 유전자의 스트레스와의... -
Activating transcription factor-3 induction is involved in the anti-inflammatory action of berberine in RAW264.7 murine macrophages

Berberine is an isoquinoline alkaloid found in Rhizoma coptidis, and elicits anti-inflammatory effects through diverse mechanisms. Based on previous reports that activating transcription factor-3 (ATF-3) acts as a negative regulator of LPS signaling, the authors investigated the possible involvement of ATF-3 in the anti-inflammatory effects of berberine. It was found berberine concentration-dependently induced the expressions of ATF-3 at the mRNA and protein levels and concomitantly suppressed...
