The Genetics of Life and Death: Virus-Host Interactions Underpinning Resistance to African Swine Fever, a Viral Hemorrhagic Disease
Conclusion and Future Perspectives The mechanisms which result in reduced viral replication and lack of disease in African wild suids after ASFV infection are largely unknown. The data so far indicate that this is not due to an intrinsic difference in the ability of the virus to replicate in macrophages from these hosts. A more likely explanation is that the innate immune system of these hosts is better able to control virus replication resulting in a reduced systemic infection and reduced pathogenesis. This may involve a balance between virus and host factors which has evolved over long term infections of these hosts. Se...

Cellular Therapies for the Treatment of Hematological Malignancies; Swine Are an Ideal Preclinical Model
The absence of clinically relevant large animal tumor models has historically forced experimental cellular therapies for hematological malignancies to translate directly from murine models to clinical trials. However, recent advances highlight swine as an ideal large animal model to demonstrate the safety of murine proof of concept studies prior to their implementation clinically. The availability of the MHC defined MGH miniature swine herd has been key for the development of novel approaches for hematopoietic cell and solid organ transplantation. New spontaneously arising hematological malignancies in these swine, specifi...

Cadmium induces apoptosis and autophagy in swine small intestine by downregulating the PI3K/Akt pathway
In conclusion, our findings suggest that Cd induces intestinal apoptosis and autophagy in swine by inactivating the PI3K/Akt signaling pathway.PMID:35091949 | DOI:10.1007/s11356-022-18863-2

Antigen detection and apoptosis in Mongolian gerbil's kidney experimentally intraperitoneally infected by swine Hepatitis E virus.
We examined the effect of Hepatitis E virus (HEV) on the renal tissue pathogenesis, morphological damages and related molecular mechanisms following swine HEV suspension intraperitoneally inoculation in Mongolian gerbils. The microscopic and ultramicroscopic analyses of kidney tissue structure were carried out at different points after inoculation of HEV. The immunohistochemistry, real-time PCR and Western blot were performed to explore the molecular mechanisms associated with HEV presence in the renal tissues. Real-time PCR revealed that the copies of HEV RNA in the kidney were detected at 7 dpi, and peaked at 14 dpi at a...

Viruses, Vol. 11, Pages 789: Crystal Structure of African Swine Fever Virus A179L with the Autophagy Regulator Beclin
c Kvansakul Subversion of programmed cell death-based host defence systems is a prominent feature of infections by large DNA viruses. African swine fever virus (ASFV) is a large DNA virus and sole member of the Asfarviridae family that harbours the B-cell lymphoma 2 or Bcl-2 homolog A179L. A179L has been shown to bind to a range of cell death-inducing host proteins, including pro-apoptotic Bcl-2 proteins as well as the autophagy regulator Beclin. Here we report the crystal structure of A179L bound to the Beclin BH3 motif. A179L engages Beclin using the same canonical ligand-binding groove that is utilized to bind to pr...

Computer-aided search for 5-arylideneimidazolone anticancer agents able to overcome ABCB1-based multidrug resistance
ChemMedChem. 2021 Apr 30. doi: 10.1002/cmdc.202100252. Online ahead of print.ABSTRACTABCB1 modulation is an interesting strategy in search for new anticancer agents overcoming multidrug resistance (MDR). Hence, 17 new 5-arylideneimidazolones containing amine moiety, as potential ABCB1 inhibitors was designed, synthesized, and investigated. The series was tested in both, parental (PAR) and multidrug resistant (MDR) overproducing ABCB1, T-lymphoma cancer cells using cytotoxicity assay. The ABCB1 modulating activity was examined in the rhodamine 123 accumulation test, followed by Pgp-Glo™ Assay to determine an influence of ...

CD177 Expression on Neutrophils: In Search of a Clonal Assay for Myeloid Neoplasia by Flow Cytometry.
Conclusions: Skewed low neutrophil CD177(%) is highly associated with clonal myeloid disorders, particularly myelodysplasia, and may be useful for detecting clonal myeloid disorders. PMID: 24124144 [PubMed - as supplied by publisher]

Molecules, Vol. 25, Pages 2258: Search for ABCB1 Modulators Among 2-Amine-5-arylideneimidazolones As a New Perspective to Overcome Cancer Multidrug Resistance
a Handzlik Multidrug resistance (MDR) is a severe problem in the treatment of cancer with overexpression of glycoprotein P (Pgp, ABCB1) as a reason for chemotherapy failure. A series of 14 novel 5-arylideneimidazolone derivatives containing the morpholine moiety, with respect to two different topologies (groups A and B), were designed and obtained in a three- or four-step synthesis, involving the Dimroth rearrangement. The new compounds were tested for their inhibition of the ABCB1 efflux pump in both sensitive (parental (PAR)) and ABCB1-overexpressing (MDR) T-lymphoma cancer cells in a rhodamine 123 accumulation assay...

Pulmonary arterial hypertension in a patient with multiple myeloma during carfilzomib treatment: in search of better management.
CONCLUSION: The mechanism responsible for cardiac and vascular events during carfilzomib therapy is unclear. This case report highlights that it is important to define at baseline the appropriate screening of patients undergoing carfilzomib therapy with specific monitoring and symptom management and that future large prospective controlled studies are needed to define the correct monitoring strategy in refractory and relapsed multiple myeloma and the potential mechanism of vascular events.
