Angiogenesis gene expression upon Notch activation in human vascular smooth muscle cells

ABSTRACT: VSMCs were cultured on Jag1 or IgG-coated plates as described above. RNA was extracted using RNA isolation kit (Qiagen).

Identification of miRNAs and their targets regulated by LIF in trophoblastic cell lines

Project description:Aim of this study was to identify miRNAs which are regulated by LIF in different trophoblastic cell lines Total RNA was reverse-transcribed, pre-amplified with miRNA-specific primers, and loaded into TaqMan Arrays. Quantitative real-time PCR was performed for 768 miRNAs. For each of two cards per sample (A and B), 9 ul of pre-amplified diluted sample was mixed with TaqMan reaction mix (Applied Biosystems) and loaded into miRNA TLDA cards (Applied Biosystems) by centrifugation. Cards were sealed, and qRT-PCR was performed with a real-time thermocycler (ABI-7900, Applied Biosystems) per manufacturer's recommendations.

Quantitative real-time PCR was performed for 768 miRNAs. For each of two cards per sample (A and B), 9 ul of pre-amplified diluted sample was mixed with TaqMan reaction mix (Applied Biosystems) and loaded into miRNA TLDA cards (Applied Biosystems) by centrifugation.

MicroRNA profiling in Acute Lymphoblastic Leukemia (ALL)

Project description:MicroRNA (667) profiling was done using TaqMan MicroRNA Arrays, which contains megaplex primer Pools covering Sanger miRBase version10 of Taqman Low Density Arrays (TLDA) platform across 50 samples along with the normals consisting of T cell lineage Acute Lymphoblastic Leukemia (T-ALL) and B cell lineage Acute Lymphoblastic Leukemia (B-ALL) subtypes which consists peripheral blood (PB) and bone marrow (BM) samples. The above isolated RNA which displayed good RIN value, linearity (R2>0.96), were used for reverse transcription (RT) reactions with the help of TaqMan MicroRNA Reverse Transcription Kit followed by PCR Reaction (ABI 7900 HT) as per illustration provided in kit. Real-time PCR was performed using an Applied Biosystems 7900 HT- TLDA Real-Time PCR System. A pre -amplification step of cDNA with pre-amp megaplex pool primers was done to significantly enhance the ability to detect highly down regulated miRNAs. The TaqMan human microRNA arrays consists of two plates, pool A and pool B. RNU 46 and RNU 48 were used as endogenous controls for data normalization. Another control not related to human is also included as a negative control. Each TaqMan Assay was run in quadruplicate. RNU 46 and RNU 48 expression was consistent in all the samples and displayed good range of CTs values 22–24 ) where as in ‘No Template’ Control (NTC) CT value was above 38. The average CT values of total profiled miRNAs in all samples were normalized with RNU 46 & RNU 48 using spotfire (statminer) software and fold change were represented in terms of log 10, 2 - Δ Δ CT (RQ ) and log10RQ. Only valid and significant miRNAs were picked up for further analysis.

MiRNA expression profiles of trophoblastic cells

Project description:To gain more insight in the expression and role of microRNAs in trophoblastic cells, we have assessed the miRNA expression pattern of four trophoblastic cell lines and have compared them with the miRNA signature of human isolated 3rd trimester cytotrophoblast cells. Total RNA was reverse-transcribed, pre-amplified with miRNA-specific primers, and loaded into TLDA cards. Quantitative real-time PCR was performed for 768 miRNAs. For each of two cards per sample (A and B), 9 ul of pre-amplified diluted sample was mixed with TaqMan reaction mix (Applied Biosystems) and loaded into miRNA TLDA cards (Applied Biosystems) by centrifugation. Cards were sealed, and qRT-PCR was performed at a real-time thermocycler (ABI-7900, Applied Biosystems) following the manufacturer's recommendations. MiRNA signatures of human primary 3rd trimester trophoblast cells were compared with those of four trophoblastic cell lines

Calcaneal tendon plasticity following gastrocnemius muscle injury in rat

Project description:We investigated calcaneal tendon extracellular matrix (ECM) remodeling after gastrocnemius muscle injury using a rat model. Wistar rats were randomly divided into four groups: control group (C; animals that were not exposed to muscle injury) and harvested at different time points post gastrocnemius muscle injury (3, 14 and 28 days) for gene expression analysis. qRT-PCR was performed using TaqMan Universal PCR Master Mix system (Applied Biosystems, CA, USA - Cat. 4304437).
