Surface‐Associated Proteins on Extracellular Vesicles Remodel the Tumor Microenvironment by Potentiating TGF‐β Signaling in a Contact‐Dependent Manner

Advanced Science, EarlyView.
Extracellular vesicles (EVs) released from TGF‐β‐activated CAFs are enriched with ECM proteins such as TSG6 and THBS1, which facilitate their binding to recipient cell membranes. This EV–cell interaction promotes the clustering of CD44 and TGF‐β receptors on the target cell surface, thereby potentiating TGF‐β signaling activity. This study highlights a

A Natural Sweetener‐inducible Genetic Switch Controls Therapeutic Protein Expression in Mammals

Advanced Science, EarlyView.
This study develops a natural sweetener, the psicose‐inducible transgene expression (PURE) system based on an Agrobacterium tumefaciens–derived transcriptional repressor PsiR. The PURE system is highly specific to psicose, being insensitive to other sugars and structurally similar molecules.

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.

Non-canonical Roles of Telomerase: Unraveling the Imbroglio

Front. Cell Dev. Biol., 2019
Telomerase plays a critical role in stem cell function and tissue regeneration that depends on its ability to elongate telomeres. For nearly two decades, it turned out that TERT regulates a broad spectrum of functions including signal transduction, gene ...

Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation

Advanced Science, EarlyView.
A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

Structural basis of template-boundary definition in Tetrahymena telomerase. [PDF]

, 2015
Telomerase is required to maintain repetitive G-rich telomeric DNA sequences at chromosome ends. To do so, the telomerase reverse transcriptase (TERT) subunit reiteratively uses a small region of the integral telomerase RNA (TER) as a template.

Telomerase Triggered DNA Walker with a Superhairpin Structure for Human Telomerase Activity Sensing.

Analytical Chemistry, 2019
Different from conventional DNA walkers, we designed a telomerase-triggered three-dimensional DNA walker consisting of a superhairpin structure with a bulged loop in the stem as the walking strand and dye-labeled tracks for ultrasensitive detection of ...

Multi-step coordination of telomerase recruitment in fission yeast through two coupled telomere-telomerase interfaces

eLife, 2016
Tightly controlled recruitment of telomerase, a low-abundance enzyme, to telomeres is essential for regulated telomere synthesis. Recent studies in human cells revealed that a patch of amino acids in the shelterin component TPP1, called the TEL-patch, is

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.
