BRCA1 and Breast Cancer: a Review of the Underlying Mechanisms Resulting in the Tissue-Specific Tumorigenesis in Mutation Carriers

Semmler L, Reiter-Brennan C, Klein A

Since the first cloning of BRCA1 in 1994, many of its cellular interactions have been elucidated. However, its highly specific role in tumorigenesis in the breast tissue—carriers of BRCA1 mutations...

Involvement of miR-Let7A in inflammatory response and cell survival/apoptosis regulated by resveratrol in THP-1 macrophage

Song J, Jun M, Ahn MR, Kim OY

BACKGROUND/OBJECTIVES: Resveratrol, a natural polyphenol, has multiple functions in cellular responses including apoptosis, survival, and differentiation. It also participates in the regulation of inflammatory response and oxidative stress. MicroRNA-Let-7A (miR-Let7A),...

Myeloid-specific SIRT1 Deletion Aggravates Hepatic Inflammation and Steatosis in High-fat Diet-fed Mice

Kim KE, Kim H, Heo RW, Shin HJ, Yi CO, Lee DH, Kim HJ, Kang SS, Cho GJ, Choi WS, Roh GS

Sirtuin 1 (SIRT1) is a mammalian NAD+-dependent protein deacetylase that regulates cellular metabolism and inflammatory response. The organ-specific deletion of SIRT1 induces local inflammation and insulin resistance in dietary and...

Resveratrol attenuates 4-hydroxy-2-hexenal-induced oxidative stress in mouse cortical collecting duct cells

Bae EH, Joo SY, Ma SK, Lee J, Kim SW

Resveratrol (RSV) may provide numerous protective eff ects against chronic inflammatory diseases. Due to local hypoxia and hypertonicity, the renal medulla is subject to extreme oxidative stress, and aldehyde products...

Nicotinamide riboside regulates inflammation and mitochondrial markers in AML12 hepatocytes

Lee HJ, Yang SJ

BACKGROUND/OBJECTIVES: The NAD+ precursor nicotinamide riboside (NR) is a type of vitamin B3 found in cow's milk and yeast-containing food products such as beer. Recent studies suggested that NR prevents...

SIRT1 Expression Is Associated with Good Prognosis in Colorectal Cancer

Jung W, Hong KD, Jung WY, Lee E, Shin BK, Kim HK, Kim A, Kim BH

  • KMID: 2277409
  • Korean J Pathol.
  • 2013 Aug;47(4):332-339.
BACKGROUND: Silent mating type information regulation 2 homolog 1 (SIRT1), an NAD+-dependent deacetylase, might act as a tumor promoter by inhibiting p53, but may also as a tumor suppressor by...
