Chondroitin Sulfate Proteoglycans in CNS Development and Pathophysiology

Journal of Neuroscience Research, Volume 104, Issue 3, March 2026.
Chondroitin sulfate proteoglycans (CSPGs) are critical components of the extracellular matrix in the central nervous system (CNS). In the developing CNS, CSPGs regulate neural precursor cells, neuronal migration, axon guidance, synapse organization, and peri‐neuronal net assembly.

Dissecting the spermatogonial stem cell niche using spatial transcriptomics

Cell Reports, 2023
Summary: Spermatogonial stem cells (SSCs) in the testis support the lifelong production of sperm. SSCs reside within specialized microenvironments called “niches,” which are essential for SSC self-renewal and differentiation.

α_MI-domain of integrin Mac-1 binds the cytokine pleiotrophin using multiple mechanisms. [PDF]

Structure
The integrin Mac-1 (αMβ2, CD11b/CD18, CR3) is an adhesion receptor expressed on macrophages and neutrophils. Mac-1 is also a promiscuous integrin that binds a diverse set of ligands through its αMI-domain.

In vitro properties of patient serum predict clinical outcome after high dose rate brachytherapy of hepatocellular carcinoma

Molecular Oncology, Volume 20, Issue 2, Page 480-492, February 2026.
Following high dose rate brachytherapy (HDR‐BT) for hepatocellular carcinoma (HCC), patients were classified as responders and nonresponders. Post‐therapy serum induced increased BrdU incorporation and Cyclin E expression of Huh7 and HepG2 cells in nonresponders, but decreased levels in responders.

Pleiotrophin promotes perineural invasion in pancreatic cancer

World Journal of Gastroenterology, 2013
Perineural invasion (PNI) in pancreatic cancer is an important cause of local recurrence, but little is known about its mechanism. Pleiotrophin (PTN) is an important neurotrophic factor. It is of interest that our recent experimental data showed its involvement in PNI of pancreatic cancer.

Pleiotrophin commits human bone marrow mesenchymal stromal cells towards hypertrophy during chondrogenesis. [PDF]

PLoS ONE, 2014
Pleiotrophin (PTN) is a growth factor present in the extracellular matrix of the growth plate during bone development and in the callus during bone healing.

The link between menin and pleiotrophin in the tumor biology of pancreatic neuroendocrine neoplasms

Cancer Science, 2022
MEN1, which encodes menin protein, is the most frequently mutated gene in pancreatic neuroendocrine neoplasms (pNEN). Pleiotrophin (PTN) has been reported as a downstream factor of menin that promotes metastasis in different tumor entities. In this study,

Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

The metastasis inducer CCN1 (CYR61) activates the fatty acid synthase (FASN)-driven lipogenic phenotype in breast cancer cells [PDF]

, 2016
The angiogenic inducer CCN1 (Cysteine-rich 61, CYR61) is differentially activated in metastatic breast carcinomas. However, little is known about the precise mechanisms that underlie the pro-metastatic actions of CCN1. Here, we investigated the impact of
