Abstract
Recent studies have demonstrated that recombinant human granulocyte macrophage colony-stimulating factor (rhGM-CSF) produced by the silkworm pupae bioreactor is absorbed into blood through oral administration and functions as an active cytokine. The aim of this study was to further examine and identify synergetic protein factors in silkworm pupae that improve rhGM-CSF absorption via an oral route. The concentrations of rhGM-CSF in serum were evaluated in mice after oral administration of rhGM-CSF using different chemical compositions of silkworm pupae as pharmaceutical excipients. The experimental data revealed that the supernatant lyophilized powder (SLP) of a homogenized slurry of silkworm pupae caused a significant increase in the rhGM-CSF level in blood when rhGM-CSF was orally administered with SLP, suggesting that synergetic protein factors that improve the oral absorption of rhGM-CSF primarily exist in SLP. As shown by scanning electron microscopy, microspheres were formed when rhGM-CSF was coated with SLP. Animal experimental data showed that the absorption of orally administered rhGM-CSF through the gastrointestinal (GI) tract primarily resulted from protein factors present in the SLP retentate obtained after 10 kDa ultrafiltration. Surface plasmon resonance spectroscopy analysis demonstrated that several protein factors present in the SLP retentate obtained after 10 kDa ultrafiltration were bound to rhGM-CSF. Proteins bound to rhGM-CSF by liquid chromatography-mass spectrometry were identified as chymotrypsin inhibitor SCI-II precursor, cationic peptide CP8 precursor, Kazal-type proteinase inhibitor, and chymotrypsin inhibitor SCI-I. These findings indicate that these proteinase inhibitors play an important role in improving rhGM-CSF absorption in the GI tract.

Abstract
Platelets are small cell fragments, produced by megakaryocytes, in the bone marrow. They play an important role in hemostasis and diverse thrombotic disorders. They are therefore primary targets of antithrombotic therapies. They are implicated in several pathophysiological pathways, such as inflammation or wound repair. In blood circulation, platelets are activated by several pathways including subendothelial matrix and thrombin, triggering the formation of the platelet plug. Studying their proteome is a powerful approach to understand their biology and function. However, particular attention must be paid to different experimental parameters, such as platelet quality and purity. Several technologies are involved during the platelet proteome processing, yielding information on protein identification, characterization, localization, and quantification. Recent technical improvements in proteomics combined with inter-disciplinary strategies, such as metabolomic, transcriptomics, and bioinformatics, will help to understand platelets biological mechanisms. Therefore, a comprehensive analysis of the platelet proteome under different environmental conditions may contribute to elucidate complex processes relevant to platelet function regarding bleeding disorders or platelet hyperreactivity and identify new targets for antiplatelet therapy.

Abstract
The Hedgehog pathway plays a crucial role in growth and patterning during embryonic development and is involved in stem cell maintenance and proliferation in adult tissues. Mutations that increase the overall activity of the pathway are often associated with a higher incidence of cancers. This article focuses on the mutations, misfoldings and deregulations of the Hedgehog pathway proteins that have been reported to be involved in different tumors, and on small molecules targeting these proteins shown to slow down the growth of certain tumors in various animal models. We propose that proteomics could be a powerful tool to identify new targets of the Hedgehog pathway, enabling the discovery of effective and novel treatments for cancers.
