The relationship between expression imbalance of adhesion molecules and asthma pathogenesis

ABSTRACT: Accumulated research has suggested the importance of the adhesion molecules modulation as therapeutic approach for bronchial asthma. Adhesion molecules expression alteration contributes to the pathogenesis of asthma. In order to probe the relationship between expression imbalance of adhesion molecules and asthma pathogenesis, expression profiling of adhesion molecules was performed using cDNA microarray. The results showed that there were various adhesion molecules with abnormal expressions in peripheral blood leucocytes of asthma patients. RNA was extracted from leucocytes in peripheral blood of 4 normal adults and 6 asthma patients by using TRIzol Reagent. Microarray expression studies were performed using the GEArray Q Series Human Extracellular Matrix & Adhesion Molecules Gene Array (SABiosciences Corporation, USA). This microarray profiles the expression of 96 genes key to the functions of cell adhesion. A negative control (PUC18DNA and blank), and the housekeeping genes including Î²-actin, GAPDH, Cyclophilin A and ribose body protein L13a were spread on each chip.

DNA damage repair gene expression profiles in cervical cancer cells radioresistant to 252Cf neutron and X-rays

Project description:[original title] Microarray analysis of DNA damage repair gene expression profiles in cervical cancer cells radioresistant to 252Cf neutron and X-rays. The aim of the study was to obtain stable radioresistant sub-lines from the human cervical cancer cell line HeLa by prolonged exposure to 252Cf neutron and X-rays. Radioresistance mechanisms were investigated in the resulting cells using SuperArray Oligo GEArrayÂ® Human DNA Damage Signaling Pathway Microarray. HeLa cells were treated with fractionated 252Cf neutron and X-rays, with a cumulative dose of 75 Gy each, over 8 months, yielding the sub-lines HeLaNR and HeLaXR.Gene expression patterns of the radioresistant sub-lines were studied through microarray analysis

E.faecalis regulate immune responses in HCT116 cells

Project description:Colonizing commensal bacteria after birth are required for the proper development of the gastrointestinal tract. It is believed that bacterial colonization pattern in neonatal gut affects gut barrier function and immune system maturation. Studies on the development of faecal flora microbiota in infants on various formula feeds showed that the neonatal gut was first colonized with enterococci followed by other flora microbiota such as Bifidobacterium in breast feeding infants. Intriguingly, Bjorksten group Other studies showed that Bbabies who developed allergy were less often colonized with Enterococcus during the first month of life as compared to healthy infants. A lot of Many studies have been done on conducted to elucidate how bifidobacteria or lactobacilli, some of which are considered probiotic, regulate infant gut immunity. However, much fewer studies have been focused on enterococi. In our study, we demonstrate that E. faecalis, isolated from healthy newborns, suppress inflammatory responses activated in vivo and in vitro. We found E. faecalis attenuates proinflammatory cytokine secretions, especially IL-8, through JNK and p38 signaling pathways. This finding shed light on how the first colonizer, E.faecalis, regulate inflammatory responses in the host. Samples are analysed using web-based GEArray Expression Analysis Suite
