In this study, we determined the expression and activation of p38 MAPK in matured porcine oocytes subjected to heat shock (HS). When MII oocytes were heated, only the phosphorylated p38 levels relative to the total p38 levels decreased (P < 0.01) after HS, but no clear relationship with HS treatments was observed in the ERK, JNK and p90(rsk) expressions of(More)
BACKGROUND Connective tissue growth factor (CTGF; also known as CCN2) is an inflammatory mediator, and shows elevated levels in regions of severe injury and inflammatory diseases. CTGF is abundantly expressed in osteoarthritis (OA). However, the relationship between CTGF and IL-6 in OA synovial fibroblasts (OASFs) is mostly unknown. METHODOLOGY/PRINCIPAL(More)
Chromomycin A3 (Chro) is capable of forming a stable dimeric complex via chelation with Ni(II), Fe(II) and Co(II). According to the circular dichroism study, the dimer conformations are significantly different among the Fe(II)-, Co(II)-, and Ni(II)-containing dimeric Chro complexes; however, the dimer conformations were preserved at high temperatures.(More)
The anticancer activity of DNA intercalators is related to their ability to intercalate into the DNA duplex with high affinity, thereby interfering with DNA replication and transcription. Polyamines (spermine in particular) are almost exclusively bound to nucleic acids and are involved in many cellular processes that require nucleic acids. Until now, the(More)
Mithramycin (Mith) forms a drug-metal complex with a 2:1 stoichiometry by chelation with a Ni(II) ion, which was determined using circular dichroism spectroscopy. Mith exhibits an increased affinity (~55 fold) for Ni(II) in the presence of DNA compared to the absence of DNA, suggesting that DNA acts as an effective template to facilitate chelation. Also, we(More)
The c-Jun N-terminal kinase (JNK) is a vital stress-activated signal that can be regulated differentially under oxidant or antioxidant conditions. Recently, we have reported that activation of JNK by cadmium chloride (Cd) contributes to apoptosis in CL3 human lung adenocarcinoma cells. Although oxidative stress has been implicated in numerous biochemical(More)
The identification of prognostic markers and establishing their value as therapeutic targets improves therapeutic efficacy against human cancers. Ribophorin II (RPN2) has been demonstrated to be a prognostic marker of human cancer, including breast and pancreatic cancers. The present study aimed to evaluate RPN2 expression in gastric cancer and to examine(More)
The development of a ligand that is capable of distinguishing among the wide variety of G-quadruplex structures and targeting telomeres to treat cancer is particularly challenging. In this study, the ability of two anthraquinone telomerase inhibitors (NSC749235 and NSC764638) to target telomeric G-quadruplex DNA was probed. We found that these ligands(More)
The authors would like to correct Fig 3D, as errors were introduced in the preparation of this figure for publication. In Fig 3D, the left JNK panel appears as a duplicate of the right JNK panel. The authors have provided a corrected version of Fig 3 here. The authors confirm that these changes do not alter their findings. The authors have provided raw,(More)
Upregulation of the metastasis-promoting S100A4 protein has been linked to tumor migration and invasion, and clinical studies have demonstrated that significant expression of S100A4 in primary tumors is indicative of poor prognosis. However, the involvement of S100A4 in the drug responsiveness of gastric cancer remains unclear. In the present study, we used(More)
