Hedgehog: A Key Signaling in the Development of the Oligodendrocyte Lineage

Journal of Developmental Biology, 2016
The Hedgehog morphogen aroused an enormous interest since it was characterized as an essential signal for ventral patterning of the spinal cord two decades ago.

The Role of the Hedgehog Pathway in Chemoresistance of Gastrointestinal Cancers

, 2021
The hedgehog pathway, which plays a significant role in embryonic development and stem cell regulation, is activated in gastrointestinal cancers. Chemotherapy is widely used in cancer treatment.

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

BMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

Biomaterials for modulating cellular responses of endogenous tendon stem/progenitor cells: A promising avenue for tendon regeneration

BMEMat, EarlyView.
This review comprehensively summarizes emerging biomaterial‐based strategies and underlying mechanisms for modulating endogenous tendon stem/progenitor cells (TSPCs). It offers the most recent insights into TSPC physiology and potential applications of tissue engineering and regenerative medicine in tendons.

Tackling cancer stemness with nanotechnology in the era of precision medicine

BMEMat, EarlyView.
Precise customization of nanoparticles (NPs) enables active targeting of cancer stem cells (CSCs), thereby improving drug delivery and therapeutic efficacy. NP‐based probing enhances CSC detection through imaging and liquid biopsy, whereas diverse therapeutic payloads improve therapeutic outcomes.

The Hedgehog Signaling Pathway Emerges as a Pathogenic Target [PDF]

Journal of Developmental Biology, 2017
The Hedgehog (Hh) signaling pathway plays an essential role in the growth, development, and homeostatis of many tissues in vertebrates and invertebrates. Much of what is known about Hh signaling is in the context of embryonic development and tumor formation.

Wnt/beta-catenin/Tcf signaling: A critical pathway in gastrointestinal tumorigenesis [PDF]

, 2002
Cancers of the gastrointestinal tract, including the liver, bile ducts, and pancreas, constitute the largest group of malignant tumors. Colorectal cancer is one of the most common neoplastic diseases in Western countries and one of the leading causes of ...

Loss, persistence and reversal of phenotypic traits

Biological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Numb is a suppressor of Hedgehog signaling and targets Gli1 for Itch-dependent ubiquitination.

, 2006
The developmental protein Numb is a major determinant of binary cell fates(1-3). It is also required for the differentiation of cerebellar granule cell progenitors (GCPs)(4) at a stage of development responsive to the morphogenic glycoprotein Hedehog(5,6)

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult
