Project description:Prostate cell lines from diverse backgrounds are important to addressing disparities in prostate cancer (PCa) incidence and mortality rates among Black men. ACRJ-PC28 was developed from a transrectal needle biopsy and established via inactivation of the CDKN2A locus and simultaneous expression of human telomerase. Characterization assays included growth curve analysis, immunoblots, IHC, 3D cultures, immunofluorescence imaging, confocal microscopy, flow cytometry, WGS and, RNA-Seq. RNA-Seq confirmed the expression of prostate specific genes alpha-methylacyl-CoA racemase (AMACR) and NKX3.1 and Neuroendocrine specific markers, synaptophysin (SYP) and enolase 2 (ENO2) and IHC confirmed the presence of AMACR. WGS confirms the absence of exonic mutations and the presence of intronic variants that appear to not affect function of AR, p53 and pRB. RNA-Seq data revealed numerous TP53 and RB1 mRNA splice variants and the lack of AR mRNA expression. The novel cell line described here should advance research addressing the disparity in prostate cancer among Black men.

Project description:Prostate cell lines from diverse backgrounds are important to addressing disparities in prostate cancer (PCa) incidence and mortality rates among Black men. ACRJ-PC28 was developed from a transrectal needle biopsy and established via inactivation of the CDKN2A locus and simultaneous expression of human telomerase. Characterization assays included growth curve analysis, immunoblots, IHC, 3D cultures, immunofluorescence imaging, confocal microscopy, flow cytometry, WGS, and RNA-Seq. ACRJ-PC28 has been passaged more than 40 times in vitro over 10 months with a doubling time of 45 hours. STR profiling confirmed the novelty and human origin of the cell line. RNA-Seq confirmed the expression of prostate specific genes alpha-methylacyl-CoA racemase (AMACR) and NKX3.1 and Neuroendocrine specific markers synaptophysin (SYP) and enolase 2 (ENO2) and IHC confirmed the presence of AMACR. Immunoblots indicated the cell line is of basal-luminal type; expresses p53 and pRB and is AR negative. WGS confirmed the absence of exonic mutations and the presence of intronic variants that appear to not affect function of AR, p53, and pRB. RNA-Seq data revealed numerous TP53 and RB1 mRNA splice variants and the lack of AR mRNA expression. This is consistent with retention of p53 function in response to DNA damage and pRB function in response to contact inhibition. Soft agar anchorage-independent analysis indicated that the cells are transformed, confirmed by principal component analysis (PCA) where ACRJ-PC28 cells cluster alongside other PCa tumor tissues, yet was distinct. The novel methodology described should advance prostate cell line development, addressing the disparity in PCa among Black men.
Project description:The National Institute of Neurological Disorders and Stroke (NINDS) Human Genetics Resource Center: DNA and Cell Line Repository (the NINDS Repository): Cerebrovascular Disease/Stroke Study
Project description:<p>The National Institute of Neurological Disorders and Stroke (NINDS) Human Genetics Resource Center: DNA and Cell Line Repository
(<a href="http://ccr.coriell.org/Sections/Collections/NINDS/?SsId=10">the NINDS Repository)</a>, banks phenotypic data and biological
samples, including from individuals with cerebrovascular disease, in order to facilitate gene discovery in neurological disorders.
Those samples are used in a number of studies, and genotyping data from studies using this resource are encouraged to be shared
via dbGaP. Many studies have already shared data in this fashion, which in turn, can be linked back to the biologicals banked at the
NINDS Repository.

<p>Stroke is the third leading cause of death in the United States, and is an acute neurological event leading to death of neural
tissues. Although the majority of strokes are ischemic strokes, meaning there is oxygen deprivation to the brain, almost 20% of strokes
are hemorrhagic, resulting from bleeding into the brain. Samples available in
<a href="http://ccr.coriell.org/Sections/Collections/NINDS/Cerebrovascular.aspx?PgId=190&coll=ND">cerebrovascular disease</a>
in the NINDS Repository, include but are not limited to those from individuals affected with the following: ischemic stroke,
hemorrhagic stroke, intracranial aneurysm (both ruptured and unruptured), transient ischemic attack, arteriovenous malformations,
and others. Many studies contribute to the NINDS Repository collection in an ongoing manner and others are being added regularly.
These studies include samples from the Vitamin Intervention for Stroke Prevention (VISP) study, the Ischemic Stroke Genetics Study
(ISGS), the Familial Intracranial Aneurysm study, and many others.
</p>
<p>There is also an associated Control collection (see <a href="./study.cgi?id=phs000004">dbGaP</a>
and <a href="http://ccr.coriell.org/Sections/Collections/NINDS/Population.aspx?PgId=194&coll=ND">
Coriell</a>). Others studies may use cases from the NINDS
repository, controls from the NINDS repository, as well as cases, and controls, from other sources. A subset of subjects from
The National Institute of Neurological Disorders and Stroke (NINDS) Human Genetics Resource Center: DNA and Cell Line Repository
(the NINDS Repository): Cerebrovascular Disease/Stroke Study was utilized in the <a href="./study.cgi?id=phs000102">Ischemic Stroke
Genetics Study (ISGS)</a> study.
