<p>(A) Left panel: Example of gating for lymphocytes (LC) and AML blasts (BL) according to SSC/CD45 signals after live gating. wt<i>RAS</i> panels: CD11c expression of wt<i>RAS</i> AML blasts (left) and LC (right) in untreated samples (solid grey curve) or samples treated with 100 nM AraC (black line). mt<i>RAS</i> panels: CD11c expression of mt<i>NRAS</i>12/13 blasts (left) and LC (right) treated as indicated above. (B) Summary of the <i>in vitro</i> responses to AraC treatment in terms of differentiation of 22 primary AML blasts with or without <i>NRAS</i> mutation. <i>Samples with differentiation</i> describes the portion of samples with differentiation response (diff. ↑) to AraC in relation to all samples in the wt<i>RAS</i> or mt<i>NRAS</i> cohort, respectively. Fisher`s exact test: p = 0.02. (C) Summary of the <i>in vitro</i> responses to AraC treatment in terms of differentiation of 22 primary AML blasts with or without FLT3-ITD.

AraC induces differentiation in the mt<i>NRAS</i> harboring AML cell line HL-60.
<p>(A) May-Grünwald-Giemsa staining of HL-60 and U937 (wt<i>RAS</i>) cells 48h after AraC treatment at indicated doses. (B) <i>CD14</i> expression in HL-60 and U937 cells 48 h after AraC-treatment at indicated doses as determined by quantitative real-time PCR. <i>GAPDH</i> was used for normalization. The graph shows the median with 95% confidence interval. Results were normalized to the respective control of each cell line. **: p = 0.002 (Student’s t-test).</p
Oncogenic <i>NRAS</i> Primes Primary Acute Myeloid Leukemia Cells for Differentiation
<div><p><i>RAS</i> mutations are frequently found among acute myeloid leukemia patients (AML), generating a constitutively active signaling protein changing cellular proliferation, differentiation and apoptosis. We have previously shown that treatment of AML patients with high-dose cytarabine is preferentially beneficial for those harboring oncogenic RAS. On the basis of a murine AML cell culture model, we ascribed this effect to a RAS-driven, p53-dependent induction of differentiation. Hence, in this study we sought to confirm the correlation between <i>RAS</i> status and differentiation of primary blasts obtained from AML patients. The gene expression signature of AML blasts with oncogenic <i>NRAS</i> indeed corresponded to a more mature profile compared to blasts with wildtype <i>RAS</i>, as demonstrated by gene set enrichment analysis (GSEA) and real-time PCR analysis of myeloid ecotropic viral integration site 1 homolog (<i>MEIS1</i>) in a unique cohort of AML patients. In addition, <i>in vitro</i> cell culture experiments with established cell lines and a second set of primary AML cells showed that oncogenic <i>NRAS</i> mutations predisposed cells to cytarabine (AraC) driven differentiation. Taken together, our findings show that AML with inv(16) and <i>NRAS</i> mutation have a differentiation gene signature, supporting the notion that <i>NRAS</i> mutation may predispose leukemic cells to AraC induced differentiation. We therefore suggest that promotion of differentiation pathways by specific genetic alterations could explain the superior treatment outcome after therapy in some AML patient subgroups. Whether a differentiation gene expression status may generally predict for a superior treatment outcome in AML needs to be addressed in future studies.</p></div
Impact of <i>NRAS</i> status on the transcriptome of primary AML blasts.

Primary AML blasts harboring wt<i>NRAS</i> were compared with mt<i>NRAS</i> (12/13 or 61) blasts. (F) Relative expression of <i>MEIS1</i> in primary AML blasts carrying wt<i>RAS</i> or mt<i>NRAS</i> as examined by real-time PCR. The graph shows the median with 95% confidence interval. Results were normalized to <i>MEIS1</i> expression of mt<i>NRAS</i> blasts. <i>GAPDH</i> expression served as internal control. *: p = 0.025 (Mann Whitney test).</p
Plasma Synthesis of Carbon-Based Nanocarriers for Linker-Free Immobilization of Bioactive Cargo
Multifunctional
nanoparticles are increasingly employed to improve
biological efficiency in medical imaging, diagnostics, and treatment
applications. However, even the most well-established nanoparticle
platforms rely on multiple-step wet-chemistry approaches for functionalization
often with linkers, substantially increasing complexity and cost,
while limiting efficacy. Plasma dust nanoparticles are ubiquitous
in space, commonly observed in reactive plasmas, and long regarded
as detrimental to many manufacturing processes. As the bulk of research
to date has sought to eliminate plasma nanoparticles, their potential
in theranostics has been overlooked. Here we show that carbon-activated
plasma-polymerized nanoparticles (nanoP<sup>3</sup>) can be synthesized
in dusty plasmas with tailored properties, in a process that is compatible
with scale up to high throughput, low-cost commercial production.
We demonstrate that nanoP<sup>3</sup> have a long active shelf life,
containing a reservoir of long-lived radicals embedded during their
synthesis that facilitate attachment of molecules upon contact with
the nanoparticle surface. Following synthesis, nanoP<sup>3</sup> are
transferred to the bench, where simple one-step incubation in aqueous
solution, without the need for intermediate chemical linkers or purification
steps, immobilizes multiple cargo that retain biological activity.
Bare nanoP<sup>3</sup> readily enter multiple cell types and do not
inhibit cell proliferation. Following functionalization with multiple
fluorescently labeled cargo, nanoP<sup>3</sup> retain their ability
to cross the cell membrane. This paper shows the unanticipated potential
of carbonaceous plasma dust for theranostics, facilitating simultaneous
imaging and cargo delivery on an easily customizable, functionalizable,
cost-effective, and scalable nanoparticle platform
