A Novel Role for CAMKK1 in the Regulation of the Mesenchymal Stem
Cell Secretome.
The study underscores the utility of a
quantitative secretome profiling strategy in identifying novel bacterial virulence factors.
In a study in Molecular & Cellular Proteomics, Xiaoyun Liu and colleagues at Peking University applied quantitative
secretome profiling to catalogue the effector proteins delivered by SPI - 1.
Quiescent PSCs in a normal pancreas act as lipid - storing cells with a
limited secretome, whereas activated PSCs in the tumor microenvironment produce a vast array of secreted proteins implicated in cancer progression.
The successful candidate will receive extensive training on proteomics - based discovery (
secretome proteomics to identify cytokines important in different children's cancers, protein expression profiling of subcellular fractions and organelles, and interactome proteomics to identify novel protein — protein interactions) and follow - up of proteomic findings (molecular cell biological characterization of protein functions and signaling).

cell secretome and its regulation by signal transduction pathways.»
Importantly, the pro-regenerative effects of CM from modified MSCs suggest that CAMKK1 acts by modulating
the secretome of MSCs to produce elevated levels of pro-reparative factors.
Therefore, PMA is a general tool for studying
the secretome and has the added specific benefit of enabling examination of secreted proteins involved in HMEC function.
Results: Researchers at Pacific Northwest National Laboratory have identified
the secretome — defined as the family of proteins secreted by cells — of human mammary epithelial cells, or HMEC.

Secretome» from STEM CELLS Translational Medicine by Stuart P. Atkinson
Narrowing the potential
secretome with these comparisons, the team's analysis yielded a conservative estimate of 151 proteins belonging directly to the secretome.
Why it matters: Because
the secretome is important for tissue function and equilibrium as well as cell communication, proliferation and organization, studying these proteins may lead to new treatments and biomarker discovery.
Therapeutic microparticles functionalized with biomimetic cardiac stem cell membranes and
secretome.
RNAseq and mass spectrometry to identify the astrocyte - specific transcriptome and
secretome, across development both in vitro and in vivo
For all cell lines, we observed a gradient of expression of the two antigens in the cell population (Figure 1a), as we reported previously, and confirmed in an independent analysis of
the secretome of human ES cells [16].
Dr. Gerlinde Van de Walle, an Assistant Professor in the department of Microbiology and Immunology, will be giving a seminar titled Bovine mammary stem cells and
their secretome: why do we care?
