Alu and L1 Retroelements Are Correlated with the Tissue Extent and Peak Rate of Gene Expression, Respectively

Kim TM, Jung YC, Rhyu MG

We exploited the serial analysis of gene expression (SAGE) libraries and human genome database in silico to correlate the breadth of expression (BOE; housekeep-ing versus tissue-specific genes) and peak rate...

Transcriptional repression of type I procollagen genes during adipocyte differentiation

Yi TG, Choi HM, Park RW, Sohn KY, Kim IS

  • KMID: 1457541
  • Exp Mol Med.
  • 2001 Dec;33(4):269-275.
Adipocyte differentiation is a very complex process in which whole-cell changes are accompanied. Among them, type I procollagen gene has been shown to specifically decrease during adipocyte differentiation; however, little...

Gene Expression Regulation by Agonist-Independent Constitutive Signaling of Melanocortin-1 Receptor

Seong I, Kim J

BACKGROUND: Melanocortin-1 receptor (Mc1r), a key signaling receptor for melanogenesis, has been reported to mediate migration of B16F10 melanoma cells. Interestingly, this activity appears to be a part of the...

Regulation of fibronectin gene expression by cyclic AMP and phorbol myristate acetate in HT-1080 human fibrosarcoma cells

Lee BH, Park RW, Kim IS

  • KMID: 755015
  • Exp Mol Med.
  • 1998 Dec;30(4):240-245.
We studied the regulation of fibronectin (FN) gene expression by cAMP and phorbol-12-myristate-13-acetate (PMA) in HT-1080 human fibrosarcoma cells. Dibutyryl cAMP increased FN synthesis and mRNA levels, while PMA inhibited...

Down-regulation of human FEN-1 gene expression during differentiation of promyelocytic leukemia cells

Kim IS

  • KMID: 755017
  • Exp Mol Med.
  • 1998 Dec;30(4):252-256.
Flap endo/exonuclease-1 (FEN-1) recognizes 5'-flap DNA structures that have been proposed to be important intermediates in DNA replication, repair and recombination, and cleaves the double strand-single strand junction of flap ...

Aberrantly expressed microRNAs in the context of bladder tumorigenesis

Lee JY, Ryu DS, Kim WJ, Kim SJ

MicroRNAs (miRNAs), small noncoding RNAs 19-22 nucleotides in length, play a major role in negative regulation of gene expression at the posttranscriptional level. Several miRNAs act as tumor suppressors or...

14-3-3epsilon protein increases matrix metalloproteinase-2 gene expression via p38 MAPK signaling in NIH3T3 fibroblast cells

Lee EK, Lee YS, Lee H, Choi CY, Park SH

One of the 14-3-3 protein isoforms, 14-3-3epsilon, was previously shown to be increased during skin aging. We suggest here a possible role for the 14-3-3epsilon protein in skin aging by...
