Epithelial-mesenchymal transition (EMT), a critical process of cancer invasion and metastasis, is associated with stemness property of cancer cells. Though Oct4 and Nanog are homebox transcription factors essential to the self-renewal of stem cells and are expressed in several cancers, the role of Oct4/Nanog signaling in tumorigenesis is still elusive.

Tubulointerstitial nephritis is a main renal manifestation caused by pathogenic leptospira that accumulate mostly in the proximal tubules, thereby inducing tubular injury and tubulointerstitial nephritis. To elucidate the role of leptospira outer membrane proteins in tubulointerstitial nephritis, outer membrane proteins from pathogenic Leptospira shermani(More)
Mouse DDA3 (mDDA3) is a microtubule-associated protein that promotes cell growth. mDDA3 contains an intronic p53 binding motif that is absent in human DDA3 (hDDA3), and is transcriptionally activated during DNA damage in a p53-dependent way. We now report that hDDA3 mRNA and protein levels were suppressed by p53, as well as in DNA damaged cells harboring(More)
Chronic inflammation leads to a progressive inflammation in certain types of cells. Recent studies report that the activation of nuclear factor kappa B (NF-κB) increases the expression of inflammation-related protein such as inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2), which further enhance the chronic inflammation, thus conduct the(More)
In Taiwan, leptospirosis is caused mainly by Leptospira santarosai serovar shermani. Suppression subtractive hybridization was employed to isolate DNA fragments present in pathogenic L. santarosai serovar shermani but absent in non-pathogenic L. biflexa serovar patoc. Analysis of 23 subtracted DNA clones revealed 25 gene fragments by BLASTX program. Eight(More)
We report the expression and characterization of the omp52 gene of Leptospira santarosai serovar Shermani strain CCF that is isolated in Taiwan. omp52 was identified among pathogenic leptospires but not among non-pathogenic leptospires by using suppression subtractive hybridization in our previous study. With an open reading frame of 1371 bp that encodes(More)
Tensin family members, including tensin2 (TNS2), are present as major components of the focal adhesions. The N-terminal end of TNS2 contains a C1 region (protein kinase C conserved region 1) that is not found in other tensin members. Three isoforms of TNS2 have been identified with previous reports describing the shortest V3 isoform as lacking the C1(More)
Chinese olives (Canarium album L.) have historically been used for medicinal purposes rather than commercially for oil. In this report, we reveal that the methanol-ethyl acetate partitioned fraction from Chinese olive fruits (MEO), of which ellagic acid accounted for 12%, exhibited profound anti-proliferative activities in the human colon cancer cell line,(More)
