Nucleus Accumbens RNA Isolation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA containing the small RNA fraction was isolated from 100mg of frozen tissue from the nucleus accumbens (NAc) using the mirVana-PARIS kit (Life Technologies, Carlsbad, CA), following manufacturer's protocols. RNA concentration was measured using the Quant-iT Broad Range RNA Assay kit (Life Technologies), and the RNA Integrity Number (RIN) was measured on the Agilent 2100 Bioanalyzer (Agilent Technologies, Inc., Santa Clara, CA). All subjects were initially included for matching based on age, sex, ethnicity, brain pH, PMI and RIN, and this yielded 18 appropriately matched case-control pairs with RINs ≥6 (N = 36).

Postmortem NAc from 42 AD cases and 42 controls was provided by the Australian Brain Donor Programs of New South Wales Tissue Resource Centre (NSW TRC) under the support of the University of Sydney, National Health and Medical Research Council of Australia, Schizophrenia Research Institute, National Institute on Alcohol Abuse and Alcoholism, and the New South Wales Department of Health.26 (link) As part of a previous study,27 (link) several criteria were used to exclude samples with (1) agonal state, (2) substantial brain damage, (3) history of infectious disease, and (4) postmortem interval (PMI) > 48 h (Table S1). Samples were further matched for RNA integrity number (RIN) (mean = 6.9, ±0.84), sex (all male), ethnicity (100% Caucasian), brain pH, and postmortem interval to minimize covariates' effect on expression, resulting in 18 matched case–control pairs (n = 36).28 (link) Total RNA from flash-frozen NAc was extracted and purified via mirVANA-PARIS kit (Life Technologies, Carlsbad, CA) following the manufacturer's protocol. RNA integrity (RIN) and concentrations were assessed via Agilent 2100 Bioanalyzer (Agilent Technologies, Inc., Santa Clara, CA) and Quant-iT Broad Range RNA Assay kit (Life Technologies), respectively.

Quantitative Analysis of LOC339975 in AD

Check if the same lab product or an alternative is used in the 5 most similar protocols
PFC and NAc tissues from 41 AD cases and 41 controls were provided by
the New South Wales Tissue Resource Centre. Age, sex,
ethnicity, brain weight, brain pH, post-mortem interval (PMI), tissue
hemisphere, cause of death, blood toxicology, smoking status, neuropathology and
liver pathology were provided for each subject. Confounding effects of all these
covariates were controlled by analysis of covariance (ANCOVA, Supplementary Table S7).
Total RNA was isolated from 100mg frozen tissue using the mirVana-PARIS kit
(Life Technologies, Carlsbad, CA) following manufacturer’s protocols.
RNA concentration was measured using the Quant-iT Broad Range RNA Assay kit
(Life Technologies). The RNA Integrity Number (RIN) was measured on the Agilent
2100 Bioanalyzer (Agilent Technologies, Inc., Santa Clara, CA). Quantitative
real-time PCR (qRT-PCR) analyses were performed as previously described using
SYBR Green (Riley et al., 2010 (link)) with
primers spanning the LOC339975 exon 2–3 junction.
Samples with missing genotypes and outliers (±2SD from the mean) were
omitted from further analysis.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
