MoSep3 and MoExo70 are needed for MoCK2 ring assembly essential for appressorium function in the rice blast fungus, Magnaporthe oryzae.

Mol Plant Pathol 2021 Jun 11. Epub 2021 Jun 11.

State Key Laboratory for Ecological Pest Control of Fujian and Taiwan Crops, College of Plant Protection, Fujian Agriculture and Forestry University, Fuzhou, China.

Polar growth during appressorium formation is vital for the penetration peg formation in the rice blast fungus, Magnaporthe oryzae. Previous research has shown that the Sln1-septin-exocyst complex, localized at the base of the appressorium in contact with the leaf surface, forms a ring structure that influences growth polarity and affects penetration peg formation, and is necessary for pathogenicity. Our previous research showed CK2 proteins assemble another ring structure positioned perpendicular to the Sln1-septin-exocyst complex. Read More

Severe Calcaneus Injury Probability Curves Due to Under-Body Blast.

Ann Biomed Eng 2021 Jun 11. Epub 2021 Jun 11.

Johns Hopkins University Applied Physics Laboratory, 11100 Johns Hopkins Road, Laurel, MD, 20723, USA.

The lower extremity is the most frequently injured body region to mounted soldiers during underbody blast (UBB) events. UBB events often produce large deformations of the floor and subsequent acceleration of the lower limb that are not sufficiently mitigated by the combat boot, leaving the calcaneus bone vulnerable to injury. Biomechanical experiments simulating UBB loading scenarios were conducted in a laboratory environment using isolated postmortem human subject (PMHS) leg components. Read More

tinguishing AML from MDS: A fixed blast percentage may no longer be optimal.

Blood 2021 Jun 10. Epub 2021 Jun 10.

University Hospital Ulm, Ulm, Germany.

Patients with acute myeloid leukemia (AML) have conventionally received more "intense" therapy than patients with myelodysplastic syndromes (MDS). Although less intense therapies are being used more often in AML, the AML-MDS dichotomy remains, with the presence of ≥ 20% myeloblasts in marrow or peripheral blood generally regarded as defining AML. Consequently, patients with 19% blasts are typically ineligible for AML studies, with patients with 21% blasts ineligible for MDS studies. Read More

MiR-130b and miR-128a are essential lineage-specific co-drivers of t(4;11) MLL-AF4 acute leukemia.

Blood 2021 Jun 10. Epub 2021 Jun 10.

University of Edinburgh, Edinburgh, United Kingdom.

t(4;11) MLL-AF4 acute leukemia is one of the most aggressive malignancies in the infant and pediatric population, yet we have little information on the molecular mechanisms responsible for disease progression. This impairs the development of therapeutic regimens that can address the aggressive phenotype and lineage plasticity of MLL-AF4-driven leukemogenesis. This study highlights novel mechanisms of disease development by focusing on two microRNAs upregulated in leukemic blasts from primary patient samples: miR-130b and miR-128a. Read More
