Drug delivery into microneedle-porated nails from nanoparticle reservoirs.

Journal of Controlled Release, 2015
This study demonstrates the potential of polymeric nanoparticles as drug reservoirs for sustained topical drug delivery into microneedle-treated human nail. Laser scanning confocal microscopy was used to image the delivery of a fluorescent model compound

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Chloronychia: The goldman–fox syndrome - Implications for patients and healthcare workers

Indian Journal of Dermatology, 2020
Nail coloration has many causes and may reflect systemic disease. White nails (leukonychia) are common; rubronychia is rare, whereas green (chloronychia) is occasionally evident.

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Oncogenic miR-19a and miR-19b co-regulate tumor suppressor MTUS1 to promote cell proliferation and migration in lung cancer

Protein & Cell, 2017
MTUS1 (microtubule-associated tumor suppressor 1) has been identified that can function as a tumor suppressor gene in many malignant tumors. However, the function and mechanisms underlying the regulation of MTUS1 are unclear.

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

Molecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

Piese de metal, os, sticlă şi piatră descoperite în cetatea de la Caraşova-Grad (com. Caraşova, jud. Caraş-Severin)

Materiale și Cercetări Arheologice, 2011
During the archaeological excavations made in Caraşova-Grad fortress (comm. Caraşova, Caraş-Severin County) in 1998, 2000 and 2001, a relatively great number of metal, glass, bone and stone items was discovered. The majority of these items were not found

miR-181b functions as an oncomiR in colorectal cancer by targeting PDCD4

Protein & Cell, 2016
Programmed cell death 4 (PDCD4) is a RNA-binding protein that acts as a tumor suppressor in many cancer types, including colorectal cancer (CRC). During CRC carcinogenesis, PDCD4 protein levels remarkably decrease, but the underlying molecular mechanism ...

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression

Molecular Oncology, EarlyView.
Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.

Emerging role of extracellular microRNAs and lncRNAs

ExRNA, 2019
The discovery of extracellular non-coding RNAs, including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), has dramatically altered our understanding of the role RNA plays in organisms.
