The article presents scientific materials on the use of method remote infrared thermography in complex diagnosis postpartum dysgalactia syndrome sows. general body temperature and skin surface individual parts its are important indicators functional state animal body. In veterinary practice, they widely used for differential various diseases. Now, most perfect way to register spatial distributi...

Pancreatic ductal adenocarcinoma (PDAC) is among the most deadly types of malignancies because of its high ability to metastasize. PDAC is thought to be under hypoxic condition. Therefore, to investigate the mechanism of metastatic processes, chronic-hypoxia-resistant PDAC cells were newly generated under hypoxic condition for 3-6 months and reoxygenation experiments were performed using these ...

Pancreatic cancers are aggressive because they are highly invasive and highly metastatic; moreover, effective treatments for aggressive pancreatic cancers are lacking. Here, we report that the motor kinesin protein KIF20A promoted the motility and invasiveness of pancreatic cancer cells through transporting the RNA-binding protein IGF2BP3 and IGF2BP3-bound transcripts toward cell protrusions al...

Poor prognosis of glioblastoma (GBM) is attributable to the propensity of tumor cells to infiltrate into the brain parenchyma. Protein kinase C (PKC) isozymes are highly expressed or aberrantly activated in GBM. However, how this signaling node translates to GBM cell invasiveness remains unknown. Here, we report that among PKC isoforms, PKCδ is strongly associated with infiltration of GBM cells...

Collagen type IV degradation results in disruption and breakdown of the normal basement membrane architecture, a key process in the initiation of tumor microinvasion into the connective tissue. PACE4, a proprotein convertase, activates membrane type matrix metalloproteinases (MT-MMPs) that in turn process collagenase type IV. Because PACE4 is overexpressed in skin carcinomas and in vitro overex...

Hyaluronic acid (HA) is abundant in tumor microenvironment and closely associated with invasiveness of glioblastoma (GBM) cells. However, the cellular mechanism underlying HA-rich microenvironment in GBM remains unexplored. Here, we show that tumor-associated mesenchymal stem-like cells (tMSLCs) contribute to abundance of hyaluronic acid (HA) in tumor microenvironment through HA synthase-2 (HAS...

We investigated the anti-metastatic effect of cordycepin (3'-deoxyadenosine) on a hematogenic metastatic mouse model which was intravenously injected with B16-BL6 melanoma cells. A 3-hour exposure to various concentrations of cordycepin (0.3, 1 and 3 microg/ml) dose-dependently reduced the number of nodules formed in lung at 15 days after the tumor injection. To elucidate the mechanism of this ...

Fab fragments of a monoclonal antibody directed against p37, a protein associated with the surface of FS9 mouse sarcoma cells, were previously found to inhibit the highly invasive behaviour of FS9 cells in vitro. We show that p37 originates from Mycoplasma hyorhinis. Infecting various cell lines with the mycoplasma consistently increased their invasiveness when confronted with chicken heart fib...

In this study we evaluated efficiency of DNAzymes to modulate motility of cancer cells, an important factor in the progression and metastasis of cancers. For this purpose we targeted β1 integrins that are predominant adhesive receptors in various carcinoma cell lines (CX1.1, HT29, LOVO, LS180, PC-3). To evaluate invasiveness of cancer cells, we used a transwell migration assay that allowed anal...

Introduced exotic species encounter a wide range of non-coevolved enemies and competitors in their new range. Evolutionary novelty is a key aspect of these interactions, but who benefits from novelty: the exotic species or their new antagonists? Paradoxically, the novelty argument has been used to explain both the release from and the suppression by natural enemies. We argue that this paradox c...
