During the same period, we worked with clinical collaborators at Duke Cancer Institute to plan our next trial for GMI-1359, a dual antagonist of E-selectin and CXCR-4
, and defined individuals with breast cancer and bone metastases as our initial target study population," said CEO Rachel King.
For the first time, this study proposed a deep learning method to automatically detect and segment the whole-body MM bone lesions on CXCR-4
An ischemic insult to the cortex can markedly increase the expression of SDF-1 in the ischemic region, which is a chemoattractant for directional migration of neuroblasts expressing CXCR-4
.[sup] Hypoxia can induce migration in various types of cells, including BMSCs, cardiac SCA-1+ progenitors, ESCs/iPSCs, NSCs, and many tumor cells.[sup],,,, The SDF-1/CXCR4 axis and hypoxia are mediators for BMSC/EPC migration in the bone marrow, the peripheral blood, and many other organs.[sup],, Upon hypoxic stimuli, IL-8 is upregulated and activated in acute myeloid leukemia immune cells, which show greater migration out of the stem cell niche.[sup]
PPAR[gamma] has positive effects on breast cell cancer: it downregulates the expression of the C-X-C chemokine receptor type 4 (CXCR-4
) gene, which is crucial in the growth and progression of cancer, as well as in the development of metastasis.

Various pharmacological activities associated with curcumin are believed to be due to its interference with diverse cell signaling pathways including cell cycle (cyclin-Dl and cyclin-E), apoptosis (activation of caspases and down-regulation of antiapoptotic gene products), proliferation (HER-2, EGFR, and AP-1), survival (P13K/Akt pathway), invasion (MMP-9 and adhesion molecules), angiogenesis (VEGF), metastasis (CXCR-4
) and inflammation (NFkB, TNF, IL-6, 1L-1, COX-2, and 5-LOX).
It revealed that the most overexpressed genes at 12 hours of treatment were chemokines CXCL1 (GRO[alpha]), IL8, C-X-C chemokine receptor type 4 (CXCR-4
), and other genes implicated in the immune response, such as pentraxin 3 (PTX3), IL6, and TNF[alpha]-induced protein 6 (TNFAIP6), or metaloproteinases (MMP1, MMP10, and MMP14).
A key chemokine implicated in the quiescence of these cells within the bone marrow is stromal derived factor-1 (SDF-1), which acts via its major receptor CXCR-4
(C-X-C chemokine receptor type 4).
The alpha-chemokine, stromal cell-derived factor-1alpha, binds to the transmembrane G-protein-coupled CXCR-4
receptor and activates multiple signal transduction pathways.
The C-C chemokines RANTES, MIP-1[alpha] and MIP-1[beta] are shown to be the natural ligands for CCR-5 and CXCR-4
However, certain persons with mutated CCR-5 can become HIV-infected (10); in such cases other chemokine receptors (e.g., CXCR-4
, CCR-2, and CCR-3) are believed to facilitate infection.
