摘要:
LSD1, a homolog of nuclear amine oxidases, functions as a histone demethylase and transcriptional co-repressor. LSD1 specifically demethylates histone H3 lysine 4, which is linked to active transcription. Lysine demethylation occurs via an oxidation reaction that generates formaldehyde. Importantly, RNAi inhibition of LSD1 causes an increase in H3 lysine 4 methylation and concomitant de-repression of target genes, suggesting that LSD1 represses transcription via histone demethylation. The results thus identify a histone demethylase conserved from S. pombe to human and reveal dynamic regulation of histone methylation by both histone methylases and demethylases.

摘要:
A therapeutic composition that includes an active portion of the lysyl oxidase pro-peptide in a pharmaceutically acceptable carrier substance and methods of using such a therapeutic composition are disclosed. The active agent does not have lysyl oxidase enzymatic activity. Preferably, the active polypeptide is active in inhibiting cell growth in soft agar and active in inhibiting tumor formation. In addition, the active polypeptide preferably comprises an active portion of the amino acid sequence given in SEQ ID NO.: 1 or SEQ ID NO.: 2, or conservative substitions thereof. Alternatively, the active polypeptide comprises a polypeptide comprising an active portion of an amino acid sequence selected from the group consisting of SEQ ID NOs.: 3-8, or conservative substitions thereof.

摘要:
Methods, compositions and kits are provided for effectively treating and preventing cancer metastasis in vivo and for increasing survival of subjects burdened with metastatic tumors by targeting a lysyl oxidase or its modulator, especially human lysyl oxidase. Also provided are methods for identifying lysyl oxidase inhibitors and the use of such inhibitors to prevent and treat tumors, particularly metastatic tumors, alone and in combination with chemotherapeutic agents. Further disclosed is the use of lysyl oxidase levels for measuring metastatic potential and survival.
