2021-02-24
Aldehyde dehydrogenase has been characterized as a cancer stem cell marker, which plays a key role in various biological processes in tumor, including cell proliferation, invasiveness and chemoresistance. Recent data of Abourbih et al reported that ALDH1 expression did not correlate with primary tum

Yang et al. investigatedPsoralidin 39, a coumestan derivative isolated from the seed of Psoralea corylifolia, regarding its effects on IR-induced pulmonary inflammation. Psoralidin 39 inhibited the IR-induced COX- 2 expression and PGE(2) production through regulation of PI3K/Akt and NF-κB pathway. A

2021-02-24
The COMT gene is involved in numerous psychological and physiologic processes, including modulation of pain. Polymorphisms in this gene have also been associated with many painful conditions, including pain sensitivity in children. Bivariate analysis demonstrated that individuals with heterozygous C

No effect on the Aβ production by γ-secretase was observed at 50μM, the highest effective concentration used in cultured stand on by the study of Flajolet et al. IC261 did also not exert a modulatory effect on the production of Aβ, Aβ and Aβ species in the cell-free assay at this concentration. γ-S

Following DEX exposure, the levels of CYP1A1 protein and activity remained unchanged, as seen in our previous in vitro study (Burkina et al., 2013). Dasmahapatra and Lee (1993) reported that 3.9μgL−1 DEX, similar to our highest tested concentration, did not change CYP1A1 protein content. An increase

2021-02-24
What are the molecular signals that guide Tfh cells as they navigate around the lymph node in the course of the immune response? It was recently reported that Tfh cells inside GCs have high expression of SIPR2, which acts to repel them from the S1P-rich lymph in the SCS and promote their retention i

2021-02-24
The importance of EBI2 for B cell function was first suggested by the dramatic upregulation of this receptor in EBV-transformed B cells and further inferred from its regulation in activated and GC B cells (Birkenbach et al., 1993, Glynne et al., 2000, Shaffer et al., 2000). An involvement of EBI2 in

Sphingosine kinase One of the enzymes closely related to DGKs are the sphingosine kinases (SKs). These enzymes catalyze the conversion of sphingosine (Sph) to sphingosine-1-phosphate (S1P). SKs and DGKs are closely related lipid kinase in term of basic enzymology and the mechanism of regulation a

Carbazole could be recrystallised from ethyl acetate to provide bright red crystals suitable for single crystal X-ray diffraction (see ). The first crop showed had crystallised preferentially as the ()-isomer (A). Examining the single crystal X-ray data of it was interesting to find that the N2C15 b

The primary aim of this study was to evaluate DAPK methylation as a tumor marker which is not only detected in the primary tumor but also in the serum of patients. We used matched pre-operative serum samples to determine the correlation of tumor and serum results. Despite an equal methylation freque

Results Discussion This study assesses impacts of HLA-DPB1 and CMV reactivation on GVHD, relapse, and OS after allo-HSCT. Here we demonstrate that HLA-DPB1 and CMV reactivation both increase aGVHD risk independently. Consistent with reported data, we show that HLA-DPB1 mismatching is associate

Rat pheochromocytoma PC12 cells have been widely used as a cell system to study intracellular signaling leading to neurite outgrowth. The advantages of using PC12 cells in the CHK studies are the fact that they naturally express the rat form of CHK and the observation that down-regulation of CHK fun

The mechanisms by which coregulators control the actions of estrogen receptors are still a topic of ongoing research. From studies in cancer cells, we have learned that a large group of coregulators have specific structural motifs that than affect their contact with ER ligand-binding domains (Heery,

2021-02-23
In the brain, E2 can modulate the mitogen-activated protein kinases/extracellular signal-regulated kinases (MAPK/ERK) pathway, which is involved in the formation of different memory types (Atkins et al., 1998, Blum et al., 1999, Schafe et al., 2000). When the MAPK/ERK signaling pathway is activated,
