Extreme Kinetic Stability and RNase Resistance of Human Telomerase RNA G‐Quadruplexes Overcome by DHX36 Helicase

Advanced Science, EarlyView.
The RNA G‐quadruplexes formed at the 5'‐end of the RNA component of human telomerase possess extreme slow unfolding rate, rendering them resistant to nuclease degradation. The helicase DHX36 overcame this kinetic barrier and significantly reduced the folded fraction.

A Novel Peptide, HS1002, Enhances Antitumor Activity via Dual Targeting of the GnRH Receptor and Human Telomerase Reverse Transcriptase in Prostate Cancer Cells. [PDF]

MedComm (2020)
HS1002, a new peptide targeting GnRHR and hTERT, demonstrates significant Anticancer activity in prostate cancer cells. The mechanism of HS1002 can be attributed to the reduction of serum testosterone levels by desensitization of GnRHR, the downregulation of hTERT expression and telomerase activity, and the enhancement of Anticancer immunity.

NUAK2 Inhibition Enhances Macromolecular Drug Delivery in a 3D Fibrotic Model of the Pancreatic Tumor Microenvironment

Advanced NanoBiomed Research, EarlyView.
Using a 3D cell culture model of the fibrotic barrier in pancreatic cancer, this work shows that inhibiting NUAK2 kinase in pancreatic stellate cells enhances macromolecular drug delivery. Mechanistically, NUAK2 inhibition disrupted actin stress fiber assembly to downregulate collagen I expression, thus enhancing macromolecular permeability.

Adenoviral targeting of malignant melanoma for fluorescence-guided surgery prevents recurrence in orthotopic nude-mouse models. [PDF]

, 2015
Malignant melanoma requires precise resection in order to avoid metastatic recurrence. We report here that the telomerase-dependent, green fluorescent protein (GFP)-containing adenovirus OBP-401 could label malignant melanoma with GFP in situ in ...

Multimaterial Triphasic Scaffold Replicates Enthesis Microenvironment to Modulate Early Cell Responses

Advanced NanoBiomed Research, EarlyView.
A bioinspired triphasic scaffold integrating 3D printed polycaprolactone and electrospun poly(lactic‐co‐glycolic acid) is developed to replicate the organization of the tendon‐to‐bone enthesis. Cyclic mechanical stimulation induces spatially defined cell morphology and lineage‐related gene expression in human mesenchymal stem cells, highlighting the ...

Molecular pathogenesis and targeted therapy of sporadic pancreatic neuroendocrine tumors [PDF]

, 2015
Over the past few years, knowledge regarding the molecular pathology of sporadic pancreatic neuroendocrine tumors (PNETs) has increased substantially, and a number of targeted agents have been tested in clinical trials in this tumor type.

Long Non‐Coding RNA H19 mediates STAT3 dependent activation of keratinocytes and fibroblasts in Systemic Sclerosis skin

Arthritis &Rheumatology, Accepted Article.
Objective Dermal Systemic Sclerosis (SSc) fibroblasts and their exosomes can activate keratinocytes in SSc, with lncRNA H19 (H19) highlighted as the most upregulated RNA in their cargo compared to healthy control (HC). The role of H19 in SSc pathogenesis has never been investigated.

Telomeres and telomerase [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2004
Telomeres are the protective DNA–protein complexes found at the ends of eukaryotic chromosomes. Telomeric DNA consists of tandem repeats of a simple, often G–rich, sequence specified by the action of telomerase, and complete replication of telomeric DNA requires telomerase.

New developments in the synthesis of emicoron [PDF]

, 2018
This paper reports on the modification of two synthetic steps in the usual protocol used for obtaining EMICORON. EMICORON is a benzo[ghi]perylen-diimide, which was synthesized for the first time in our laboratory in 2012, and has shown to have in vivo ...

Intracellular self‐assembled nanoneedles for efficient lysosomal escape and CRISPR/Cas9 mediated gene editing

BMEMat, EarlyView.
PlaMnB was formed by cytolysin A‐tumor homing peptides (THP)‐modified bacterial membranes encapsulating the clustered regularly interspaced short palindromic repeat/CRISPR‐associated protein (CRISPR/Cas9) plasmid and manganese dioxide. THP‐containing bacterial membrane enhances PlaMnB vascular permeability and tumor targeting, and after cellular ...
