Abstract
INTRODUCTION Hydrogel nanoparticles, also known as nanogels (NGs), have been recently proposed as alternative supramolecular vehicles for the delivery of biologically relevant molecules like anticancer drugs and contrast agents. The inner compartment of peptide based NGs can be opportunely modified according to the chemical features of the cargo, thus improving its loading and release. A full understanding of the intracellular mechanism involved in nanogel uptake by cancer cells and tissues would further contribute to the potential diagnostic and clinical applications of these nanocarriers, allowing the fine tuning of their selectivity, potency, and activity. The structural characterization of nanogels were assessed by Dynamic Light Scattering (DLS) and Nanoparticles Tracking Analysis (NTA) analysis. Cells viability of Fmoc-FF nanogels was evaluated by MTT assay on six breast cancer cell lines at different incubation times (24, 48, and 72 h) and peptide concentrations (in the range 6.25 × 10-4 ÷ 5·10-3 × wt%). The cell cycle and mechanisms involved in Fmoc-FF nanogels intracellular uptake were evaluated using flow cytometry and confocal analysis, respectively. Fmoc-FF nanogels, endowed with a diameter of ~130 nm and a zeta potential of ~-20.0/-25.0 mV, enter cancer cells via caveolae, mostly those responsible for albumin uptake. The specificity of the machinery used by Fmoc-FF nanogels confers a selectivity toward cancer cell lines overexpressing the protein caveolin1 and efficiently performing caveolae-mediated endocytosis.

Abstract
![]()
Barcoding and pooling cells for processing as a composite
sample
are critical to minimize technical variability in multiplex technologies.
Fluorescent cell barcoding has been established as a standard method
for multiplexing in flow cytometry analysis. In parallel, mass-tag
barcoding is routinely used to label cells for mass cytometry. Barcode
reagents currently used label intracellular proteins in fixed and
permeabilized cells and, therefore, are not suitable for studies with
live cells in long-term culture prior to analysis. In this study,
we report the development of fluorescent palladium-based hybrid-tag
nanotrackers to barcode live cells for flow and mass cytometry dual-modal
readout. We describe the preparation, physicochemical characterization,
efficiency of cell internalization, and durability of these nanotrackers
in live cells cultured over time. In addition, we demonstrate their
compatibility with standardized cytometry reagents and protocols.
Finally, we validated these nanotrackers for drug response assays
during a long-term coculture experiment with two barcoded cell lines.
This method represents a new and widely applicable advance for fluorescent
and mass-tag barcoding that is independent of protein expression levels
and can be used to label cells before long-term drug studies.

Abstract
Hyaluronic acid (HA), through its interactions with the cluster of differentiation 44 (CD44), acts as a potent modulator of the tumor microenvironment, creating a wide range of extracellular stimuli for tumor growth, angiogenesis, invasion, and metastasis. An innovative antitumor treatment strategy based on the development of a nanodevice for selective release of an inhibitor of the HA-CD44 interaction is presented. Computational analysis was performed to evaluate the interaction of the designed tetrahydroisoquinoline-ketone derivative (JE22) with CD44 binding site. Cell viability, efficiency, and selectivity of drug release under acidic conditions together with CD44 binding capacity, effect on cell migration, and apoptotic activity were successfully evaluated. Remarkably, the conjugation of this CD44 inhibitor to the nanodevice generated a reduction of the dosis required to achieve a significant therapeutic effect.
