TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Organ Size: The Role of Mobile Signals [PDF]

open access: yesCurrent Biology, 2010
SummaryWhat controls where, how fast and how long an organ will grow? A mobile signal regulated by a plant cytochrome P450 provides a new piece to the puzzle.

Control of growth and organ size in Drosophila.

open access: yes, 2002
Transplantation experiments have shown that developing metazoan organs carry intrinsic information about their size and shape. Organ and body size are also sensitive to extrinsic cues provided by the environment, such as the availability of nutrients ...

Size‐specific, scanner‐independent organ dose estimates in contiguous axial and helical head CT examinations

open access: yes, 2014
PurposeAAPM Task Group 204 introduced size-specific dose estimates for pediatric and adult patients undergoing body CT examinations. This investigation extends that work to head CT exams by using Monte Carlo simulations to develop size-specific, scanner ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Non-cell-autonomously coordinated organ size regulation in leaf development

open access: yes, 2010
The way in which the number and size of cells in an organ are determined poses a central challenge in our understanding of organ size control. Compensation is an unresolved phenomenon, whereby a decrease in cell proliferation below some threshold level ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Organ size determination and the limits of regulation [PDF]

open access: yesCell Cycle, 2008
The size of an organism dictates both its functional challenges and how it meets them. Despite being a universal feature of all living creatures, how an organism determines its size, and that of its internal organs, is largely unknown. In particular, the mechanisms by which organs sense magnitude and alter cellular behavior to ensure symmetry ...

The E3 Ubiquitin Ligase BIG BROTHER Controls Arabidopsis Organ Size in a Dosage-Dependent Manner

open access: yes, 2006
SummaryOrgan growth up to a species-specific size is tightly regulated in plants and animals [1, 2]. Final organ size is remarkably constant within a given species, suggesting that a species-specific size checkpoint terminates organ growth in a ...

Epithelial to mesenchymal transition in breast cancer : a novel murine model system and the regulatory role of tead transcription factors [PDF]

open access: yes, 2012
Cancer is a leading cause of death worldwide, accounting for 7.6 million, or ~13% of all deaths in 2008. The majority of cancers arise from epithelia. Breast cancer, originating from the mammary epithelium, is the most frequent cancer in women worldwide.
