Toward synaptic transcriptomes: Direct sequencing and identification of RNAs actively transported by the kinesin complex from the cell body to synapses in Aplysia neurons

ABSTRACT: Specific mRNAs are transported from the cell body to synapses where their translation can modify communication of pre-existing synapses and induce formation of new synaptic connections in response to learning. Little is known, however, about the identity of the RNAs that are actively transported and when and how these RNAs are utilized during learning. By focusing on RNAs that are associated with kinesin, a motor protein that transports gene products from the cell body to synapses, we have now applied microarrays and 454 sequencing to identify actively transported RNAs from the Aplysia central nervous system. Using a library prepared from the kinesin complex immunoprecipitated from the central nervous system (CNS), we have identified thousands of unique transcripts, of which ~600 mRNAs were annotated.

Kinesin-associated RNA: RNA co-immunoprecipitated with Kinesin IP vs RNA from Aplysia CNS

Project description:Whole genome transcriptional profiling is used to identify ESTs found in RNA co-immunoprecipitated from Aplysia CNS with antibodies against Aplysia Kinesin Heavy Chain (ApKHC) RNA derived from Aplysia CNS served as control in the opposite channel. Custom Aplysia EST array to probe the samples was designed and ordered from Agilent.

Chromosome 20q amplification regulates in vitro response to Kinesin-5 inhibitor

Project description:We identified gene expression signatures predicting responsiveness to a Kinesin-5 (kinesin spindle protein, KIF11) inhibitor (Kinesin-5i) in cultured colon tumor cell lines. Genes predicting resistance to Kinesin-5i were enriched for those from chromosome 20q, a region of frequent amplification in a number of tumor types. siRNAs targeting genes in this chromosomal region identified AURKA, TPX2 and MYBL2 as genes whose disruption enhances response to Kinesin-5i. Taken together, our results show functional interaction between these genes, and suggest that overexpression of AURKA, TPX2 and MYBL2 is functionally involved in resistance to Kinesin-5i. Furthermore, our results suggest that patients whose tumors overexpress AURKA due to amplifications of 20q will be more likely to resist treatment with Kinesin-5 inhibitor, and that inactivation of AURKA may sensitize these patients to treatment.

Specific kinesin expression profiles associated with taxane resistance in breast cancer

Project description:Purpose: Breast cancer is a genetically heterogenous disease with subtypes differing in prognosis and chemosensitivity. The basal-like breast cancer (BLBC) molecular subtype is associated with poorer outcomes, but is more responsive to taxane-based chemotherapy. We evaluated the role of kinesins, motor proteins interacting with microtubules, in influencing taxane resistance. Experimental Design: Kinesin (KIF) expression was studied in one local dataset comprising all taxane resistant breast cancers in relation to taxane resistance. Data in the NCI-60 cell line dataset (GSE5846) nd the MDACC dataset (GSE20194) is separately detailed. Results: In the local dataset, the kinesin KIF26B is overexpressed in taxane-resistant residual breast cancers post-chemotherapy. Conclusions: We show that kinesin overexpression correlates with taxane resistance in BLBC cell lines and tissue. Our results suggest a potential approach to overcoming taxane resistance through concurrent or sequential use of kinesin inhibitors, highlighting the ATP-binding domain as a drug development target. Kinesin (KIF) expression was studied in one local dataset comprising all taxane resistant breast cancers in relation to taxane resistance. Data in the NCI-60 cell line dataset (GSE5846) and the MDACC dataset (GSE20194) is separately detailed.
