The invention provides peptides that bind Tissue Factor Pathway Inhibitor (TFPI), including TFPI-inhibitory peptides, and compositions thereof. The peptides may be used to inhibit a TFPI, enhance thrombin formation in a clotting factor-deficient subject, increase blood clot formation in a subject, treat a blood coagulation disorder in a subject, purify TFPI, an identify a TFPI-binding compound.

The present invention relates to a marker which can be used to diagnose a diabetic retinopathy patient and determine the progression of diabetic retinopathy, a composition for diagnosing diabetic retinopathy, which comprises an agent for measuring the level of a gene or protein associated with the marker, and the use thereof.

The invention provides peptides that bind Tissue Factor Pathway Inhibitor (TFPI), including TFPI-inhibitory peptides, and compositions thereof. The peptides may be used to inhibit a TFPI, enhance thrombin formation in a clotting factor-deficient subject, increase blood clot formation in a subject, treat a blood coagulation disorder in a subject, purify TFPI, an identify a TFPI-binding compound.

Methods and compositions are provided for assessing (e.g., diagnosing), treating, and preventing diseases, especially cancer, and particular lung cancer, using lung cancer markers (LCM). Individual LCM and panels comprising multiple LCM are provided for these and other uses. Methods and compositions are also provided for determining or predicting the effectiveness of a treatment or for selecting a treatment using LCM. Methods and compositions are further provided for modulating cell function using LCM. Also provided are compositions that modulate LCM (e.g., antagonists or agonists), such as antibodies, proteins, small molecule compounds, and nucleic acid agents (e.g., RNAi and antisense agents), as well as pharmaceutical compositions thereof. Further provided are methods of screening for agents that modulate LCM, and agents identified by these screening methods.
