Intracellular Ca2+ is not essential for SHH signaling but is promoted by Shh ligand in embryonic fibroblasts

BMC Molecular and Cell Biology
Background Sonic Hedgehog (SHH) signaling pathway controls cell proliferation, differentiation, and organ formation. The changes in Ca2+ and their regulatory role in the context of activated SHH signaling have not been fully examined.

SHh activity and localization is regulated by perlecan [PDF]

Biological Research, 2011
Proliferation and cell fate determination in the developing embryo are extrinsically regulated by multiple interactions among diverse secreted factors, such as Sonic Hedgehog (SHh), which act in a concentration-dependent manner.

Genomic and dietary discontinuities during the Mesolithic and Neolithic in Sicily

iScience, 2022
Summary: Sicily is a key region for understanding the agricultural transition in the Mediterranean because of its central position. Here, we present genomic and stable isotopic data for 19 prehistoric Sicilians covering the Mesolithic to Bronze Age ...

The transcriptional landscape of Shh medulloblastoma [PDF]

Nature Communications, 2021
AbstractSonic hedgehog medulloblastoma encompasses a clinically and molecularly diverse group of cancers of the developing central nervous system. Here, we use unbiased sequencing of the transcriptome across a large cohort of 250 tumors to reveal differences among molecular subtypes of the disease, and demonstrate the previously unappreciated ...

Foxj1a is expressed in ependymal precursors, controls central canal position and is activated in new ependymal cells during regeneration in zebrafish [PDF]

Open Biology, 2017
Zebrafish are able to regenerate the spinal cord and recover motor and sensory functions upon severe injury, through the activation of cells located at the ependymal canal.

miR-7 Controls the Dopaminergic/Oligodendroglial Fate through Wnt/β-catenin Signaling Regulation

Cells, 2020
During the development of the central nervous system, the proliferation of neural progenitors and differentiation of neurons and glia are tightly regulated by different transcription factors and signaling cascades, such as the Wnt and Shh pathways.

Combined HIF-1α and SHH Up-Regulation Is a Potential Biomarker to Predict Poor Prognosis in Postoperative Hepatocellular Carcinoma

Journal of Investigative Surgery, 2022
Background Hypoxia-inducible factor-1α (HIF-1α) or sonic hedgehog (SHH) is associated with hepatocellular carcinoma (HCC) progression. Hypoxia inhibits ferroptosis, which induces cancer cell death. However, the correlation between the combined HIF-1α and

STAT3 is required for Smo‐dependent signaling and mediates Smo‐targeted treatment resistance and tumorigenesis in Shh medulloblastoma

Molecular Oncology, 2022
Sonic hedgehog (Shh)‐driven medulloblastoma (Shh MB) cells are dependent on constitutive Shh signaling, but targeted treatment of Shh MB has been ineffective due to drug resistance.

Crosstalk between Shh and TGF-β signaling in cyclosporine-enhanced cell proliferation in human gingival fibroblasts. [PDF]

PLoS ONE, 2013
BACKGROUND: Immunosuppressant cyclosporine-A induces gingival hyperplasia, which is characterized by increased fibroblast proliferation and overproduction of extracellular matrix components and regulated by transforming growth factor-beta (TGF-β).
