AIMTo study the mechanism of butylated hydroxyanisole-induced neural differentiation of fetal liver cells in vitro.

METHODS14.5-day-old mouse fetal liver-derived cells were cultured, and were induced by 200 micromol/L butylated hydroxyanisole (BHA) combined with PI3K inhibitor LY294002 (20 micromol/L), and then were incubated in serum-free medium. Expression of genes in treated or untreated cells were assayed by Western blotting or RT-PCR.

RESULTSThere was low level of neurofilament-L (NF-L) and brain factor-1 (BF-1) but no neurofilament-H (NF-H) and tyrosine hydroxylase (TH) in fetal liver cells. BHA promoted significantly expression of neuron-specific NF-L, NF-H, BF-1, and TH in fetal liver cells. NF-L mRNA increased 5.8 fold, NF-H mRNA 8.0 fold, BF-1 mRNA 2.68 fold, and TH mRNA 30 fold, respectively (all P < 0.01 vs untreated cells). NF-L protein increased 11.29 fold, NF-H 5.5 fold, BF-1 2.53 fold, TH 4.76 fold. Moreover, expression of these BHA-induced genes were inhibited by PI3K inhibitor LY294002.

CONCLUSIONBHA induced neural differentiation of fetal liver cells through PI3K.

OBJECTIVETo investigate the regulatory effects of lanthanum chloride (LaCl3) on the activation of nuclear factor kappa B inhibitor (IκB) kinase beta (IKKβ) induced by tumor necrosis factor alpha (TNF-α).

METHODS(1) Hela cells were cultured routinely in vitro. One portion of cells were collected and divided into TNF-α group (cultured with serum-free RMPI 1640 medium containing 20 ng/mL TNF-α for 30 min), low-dose LaCl3 + TNF-α group, moderate-dose LaCl3 + TNF-α group, high-dose LaCl3 + TNF-α group, LaCl3 group (cultured with serum-free RMPI 1640 medium containing 100 µmol/L LaCl3 for 30 min), and control group (cultured with serum-free RMPI 1640 medium for 30 min) according to the random number table. Cells in low-dose LaCl3 + TNF-α group, moderate-dose LaCl3 + TNF-α group, high-dose LaCl3 + TNF-α group were first cultured with serum-free RMPI 1640 medium containing 5, 25, 100 µmol/L LaCl3 for 4 h, and then stimulated with serum-free RMPI 1640 medium containing 20 ng/mL TNF-α for 30 min. There were 3 samples in each group. Cells were collected for detection of intracellular location of NF-κB/p65 protein by immunofluorescence staining. (2) Another portion of cells were collected and divided into TNF-α group, low-dose LaCl3 + TNF-α group, moderate-dose LaCl3 + TNF-α group, high-dose LaCl3 + TNF-α group, and control group with the same treatment as above. There were 3 samples in each group. The protein levels of NF-κB/p65 in nuclei, and the protein levels of IκBα, phosphorylated IκBα (p-IκBα) as well as IKKβ and phosphorylated IKKβ (p-IKKβ) in cytoplasm were determined by Western blotting. The binding activity between NF-κB/p65 in the nuclear and target gene was determined by NF-κB/p65 transcription factor kit (denoted as absorption value). Data were processed with analysis of variance or LSD-t test.

RESULTS(1) High expression of NF-κB/p65 was observed in cytoplasm of control group. High expression of NF-κB/p65 was observed in nuclei of TNF-α group. The expression of NF-κB/p65 in cytoplasm of LaCl3 group was lower than that of control group. In groups treated with LaCl3 and TNF-α, NF-κB/p65 expression levels in nuclei and cytoplasm were decreased along with the increase in the concentration of LaCl3, which were all lower than those in TNF-α group. (2) There was certain amount of NF-κB/p65 protein expressed in nuclei of control group. The expression of NF-κB/p65 protein in nuclei of TNF-α group was higher than that of control group. In groups treated with LaCl3 and TNF-α, the expressions of NF-κB/p65 protein in nuclei were decreased along with an increase in the concentration of LaCl3. The level of IκBα in TNF-α group was significantly decreased but that of p-IκBα increased as compared with those in control group. Along with the increase in the concentration of LaCl3, the levels of IκBα gradually increased and the levels of p-IκBα gradually decreased in groups treated with LaCl3 and TNF-α. There were no statistical differences in expression levels of IKKβ among the 5 groups. The expression of p-IKKβ could be hardly observed in control group, but it was obviously increased in TNF-α group. The expression levels of p-IKKβ in groups treated with LaCl3 and TNF-α were gradually decreased along with the increase in the concentration of LaCl3. The absorption value in TNF-α group was 0.39 ± 0.03, which was higher than that in control group (0, t = -7.23, P<0.01). The absorption values in low-dose LaCl3 +TNF-α group, moderate-dose LaCl3 + TNF-α group, and high-dose LaCl3 +TNF-α group were respectively 0.17 ± 0.03, 0.15 ± 0.03, and 0, which were obviously lower than that in TNF-α group (with t values respectively -6.54, -5.92, -7.23, P values all below 0.01).

CONCLUSIONSLaCl3 can block the activation of NF-κB signaling pathway by blocking the phosphorylation of IKKβ of Hela cells.

OBJECTIVETo improve the accuracy and sensitivity of cell membrane chromatography (CMC) and evaluate the feasibility of CMC in the study of subtype receptors.

METHODSPlasmids were used to transfer alpha(1B)-AR cDNA into human embryonic kidney 293 (HEK293) cell lines to obtain cell lines stably overexpressing the subtype receptors. HEK293 alpha(1B) cell membrane stationary phase (CMSP) was prepared by immobilizing the cell membrane on silica. The retention time of 9 alpha(1)-adrenoceptor ligands and capacity factors(kappa'(HEK293 alpha1B)) were calculated. The capacity factors of rat liver tissue and primary cultured rat hepatocytes were also calculated for a correlation analysis.

RESULTSThe calculated capacity factors (kappa') were positively correlated to the published pKi values. The affinity rank orders were identical. The longest retention of the 9 alpha(1)-adrenoceptor ligands occurred on CMSP prepared with HEK293 alpha(1B) cell lines, while CMSP obtained from rat liver tissue showed the shortest retention of the ligands.

CONCLUSIONCMC proves practical in the study of the subtype adrenoceptors. The accuracy and sensitivity of CMC can be improved using HEK293 alpha(1B) cell membrane.

OBJECTIVETo isolate, culture and identify a dog periodontal ligament stem cells (PDLSC) line in vitro.

METHODSThe adult dog periodontal ligament cells were isolated by limited dilution of culture cell for single cell clone. Cells originated from one of these clones were assessed through colony-forming efficiency and immunocytochemistry assay and alkaline phosphatase stain was used to identify the source of adult dog periodontal stem cells, at the same time, PDLSC were induced with mineralizatin solution and was found to have long protrude like an osteoblast. Differentiation of PDLSC were assessed. Mineralized potential was studied by Von-Kossa staining.

RESULTSThe dog PDLSC expressed STRO-1, which was the marker of mesenchymal stem cells. Also Vimentin, osteoblast-like marker alkaline phosphatase and Collagen-I expressed weakly. Cells were clonegenic, highly proliferative cells and capable of differentiating into osteoblasts/cementoblasts.

CONCLUSIONThe evidence suggests that the cultured cells were stem cells from adult dog periodontal ligament.

BACKGROUNDStathmin was identified as an endometriosis-related protein by comparative proteomics in our previous study. As a microtubule-destabilizing factor, stathmin was shown to participate in the relay and integration of diverse intracellular signaling pathways involved in cell proliferation, differentiation, and many other cellular activities. To investigate whether stathmin is involved in the pathogenesis of endometriosis, we examined the expression of stathmin in eutopic endometrium of women with or without endometriosis.

METHODSEutopic endometrium samples were collected from thirty-six patients who were diagnosed as endometriosis and the nineteen age-matched patients who were confirmed to be free of endometriosis surgically and histologically. The expression of stathmin mRNA was detected by real-time PCR, and its protein was detected by Western blotting and immunohistochemistry.

RESULTSStathmin was overexpressed in eutopic endometrium of women with endometriosis detected by real-time PCR in mRNA levels and by Western blotting in protein levels, without significant difference between proliferative and secretory phase. Immunohistochemistry showed that stathmin protein was localized in both endometrial glandular and stromal cells throughout the menstrual cycle.

CONCLUSIONSStathmin is overexpressed in endometrium of patients with endometriosis and may play a role in the pathogenesis of endometriosis.
