Integrating PARP Inhibitors in mCRPC Therapy: Current Strategies and Emerging Trends.

Metastatic castrate-resistant prostate cancer (mCRPC) is associated with poor prognosis. DNA damage response (DDR) genes are commonly altered in mCRPC rendering them as promising therapeutic targets. Poly (ADP ribose) polymerase inhibitors (PARPi) demonstrated antitumor activity in mCRPC patients with DDR gene mutations through synthetic lethality.

Generation of a Well-Characterized Homozygous Chromodomain-Helicase-DNA-Binding Protein 4 Mutant hESC Line Using CRISPR/eCas9 (ULIEGEe001-A-1).

The chromatin remodeler Chromodomain-helicase-DNA-binding protein 4 (CHD4) is crucial for the development of multiple organ systems. Functional mutations of CHD4 have recently been described in a developmental disorder, namely Siffrim-Hitz-Weiss syndrome (SIHIWES). Herein, we have generated a homozygous CHD4G1003D hESC line (WAe025-A-1) using CRISPR/eCas9-based gene editing in the WA-25 hESC line.

ATP-Dependent Chromatin Remodellers in Inner Ear Development.

During transcription, DNA replication and repair, chromatin structure is constantly modified to reveal specific genetic regions and allow access to DNA-interacting enzymes. ATP-dependent chromatin remodelling complexes use the energy of ATP hydrolysis to modify chromatin architecture by repositioning and rearranging nucleosomes. These complexes are defined by a conserved SNF2-like, catalytic ATPase subunit and are divided into four families: CHD, SWI/SNF, ISWI and INO80.

Association of TOR1A and GCH1 Polymorphisms with Isolated Dystonia in India.

Isolated dystonia is a common movement disorder often caused by genetic mutations, although it is predominantly sporadic in nature. Common variants of dystonia-related genes were reported to be risk factors for idiopathic isolated dystonia. In this study, we aimed to analyse the roles of previously reported GTP cyclohydrolase (GCH1) and Torsin family 1 member A (TOR1A) polymorphisms in an Indian isolated dystonia case-control group.

Generation of a FMR1 homozygous knockout human embryonic stem cell line (WAe009-A-16) by CRISPR/Cas9 editing.

Mutations in FMR1 gene is the cause of Fragile X Syndrome (FXS) leading inherited cause of intellectual disability and autism spectrum disorders. FMR1 gene encodes Fragile X Mental Retardation Protein (FMRP) which is a RNA binding protein and play important role in synaptic plasticity and translational regulation in neurons. We have generated a homozygous FMR1 knockout (FMR1-KO) hESC line using CRISPR/Cas9 based genome editing.

Dopamine β Hydroxylase (DBH) is a potential modifier gene associated with Parkinson's disease in Eastern India.

Background: Parkinson's disease (PD) is the debilitating movement disorder, distinguished by dopaminergic and norepinephrinergic neurodegeneration. Apart from candidate gene mutations, several modifier loci have been reported to be associated with the disease manifestation. The Dopamine β-Hydroxylase (DBH) maintains cellular dopamine content and regulates dopamine turn over in neurons.

A Compound Heterozygote for GCH1 Mutation Represents a Case of Atypical Dopa-Responsive Dystonia.

Dopa-responsive dystonia (DRD), a movement disorder, is characterized by young onset dystonia and dramatic response to levodopa treatment. However, the wide range of phenotypic spectrum of the disease often leads to misdiagnosis. DRD is usually caused by mutation in GCH1 gene coding for GTP cyclohydrolase 1 (GTPCH1) enzyme, which is involved in biosynthesis of tetrahydrobiopterin (BH4) and dopamine.

Genetic screening of THAP1 in primary dystonia patients of India.

Background: Primary Dystonia is a common movement disorder manifested by dystonic symptoms only. DYT6, a major genetic factor, plays a significant role in primary pure dystonia pathogenesis. In this study we analyzed THAP1 (DYT 6) gene in primary pure dystonia patients, which has been widely studied in other populations but not in Indians.

Isolation of a Pseudomonas aeruginosa strain from soil that can degrade polyurethane diol.

Polyurethane diol (PUR-diol), a synthetic polymer, is widely used as a modifier for water-soluble resins and emulsions in wood appliances and auto coatings. Non-biodegradability of polyurethanes (PUR) and PUR-based materials poses a threat to environment that has led scientists to isolate microbes capable of degrading PUR. However, the bio-degradation of PUR-diol has not yet been reported.
