Abstract:
Des mutations dans plusieurs gènes ont été liés à la sclérose latérale amyotrophique (SLA),en particulier dans celui codant pour la protéine Fused in Sarcoma (FUS). Les mutations sont retrouvées dans la partie codant pour le signal de localisation nucléaire, rendant la protéine anormalement abondante dans le cytoplasme. Combiné à d’autres observations, ça suggère qu’un gain de fonction toxique de FUS dans le cytoplasme serait à l’origine de la neurodégénérescence.

Abstract:
The multi-functional RNA binding protein FUS was identified as an androgen down-regulated target in a 2D proteomic screen in the LNCaP cell line. This screen was designed to identify novel markers and therapeutic targets for prostate cancer. Cell cycle analysis and growth assays revealed that increased FUS levels in LNCaP cells resulted in inhibition of the androgen-dependent G1-S cell cycle transition and induced apoptosis. This is brought about, in part, via the FUS-dependent modulation of the expression of G1- S check-point regulatory proteins, including decreased expression of Cyclin D1. T

Abstract:
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by motor neuron death and subsequent muscle atrophy. Approximately 15% of ALS cases are inheritable, and mutations in the Fused in Sarcoma (FUS) gene contribute to approximately 5% of these cases, as well as about 2% of sporadic cases. FUS performs a diverse set of cellular functions, including being a major regulator of RNA metabolism. FUS undergoes liquid- liquid phase transition in vitro, allowing for its participation in stress granules and RNA transport granules. Phase transition also contributes to the

Abstract:
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease is a fatal neurodegenerative disease. ALS is typically adult onset and is characterized by rapidly progressive loss of both upper and lower motor neurons that leads to death usually within 3-5 years. About 90% of all the cases are sporadic with no family history while the remaining 10% are familial cases with mutations in several genes including SOD1, FUS/TLS, TDP43 and C9ORF72.

Abstract:
Nucleocytoplasmic transport (NCT) declines during aging and in the context of age-dependent neurodegenerative diseases. However, the mechanisms underlying NCT decline in the disease are poorly understood. FUS is an RNA binding protein that shuttles between the nucleus and cytoplasm and is actively involved in NCT. Mutations in FUS cause amyotrophic lateral sclerosis (ALS), a fatal and incurable motor neuron disorder. We sought to understand the disease mechanism underlying FUS-induced NCT decline in ALS. Here, I uncovered NCT-related defects in motor neurons derived from human induced pluripot

The functional outcome of SGs is proper translational regulation and signaling, allowing cells to overcome stress.

Alternative splicing is an essential regulatory layer of gene expression that expands the coding potential of the genome in multicellular organisms. The spliceosome -the sophisticated machinery involved in intron removal- allows versatile regulation of gene expression programs. The splicing process relies on the dynamic interplay between hundreds of components of the spliceosome, and the steps at which the complex process of the splicing reaction can be regulated remain largely unknown.
