Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

open access: yesBoreas, EarlyView.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.

The TGFβ type I receptor TGFβRI functions as an inhibitor of BMP signaling in cartilage. [PDF]

open access: yes, 2019
The type I TGFβ receptor TGFβRI (encoded by Tgfbr1) was ablated in cartilage. The resulting Tgfbr1 Col2 mice exhibited lethal chondrodysplasia. Similar defects were not seen in mice lacking the type II TGFβ receptor or SMADs 2 and 3, the intracellular ...

Development of NAFLD‐Specific Human Liver Organoid Models on a Microengineered Array Chip for Semaglutide Efficacy Evaluation

open access: yesCell Proliferation, EarlyView.
Microporous array organ chips were integrated with commercially available well plates to develop organoid chip platforms, which enable modelling of hepatic physiology and non‐alcoholic fatty liver disease (NAFLD) pathogenesis, as well as evaluation of semaglutide therapeutics. ABSTRACT Progressive non‐alcoholic fatty liver disease (NAFLD) may culminate

Activin signaling is an essential component of the TGF-β induced pro-metastatic phenotype in colorectal cancer

open access: yesScientific Reports, 2017
Advanced colorectal cancer (CRC) remains a critical health care challenge worldwide. Various TGF-β superfamily members are important in colorectal cancer metastasis, but their signaling effects and predictive value have only been assessed in isolation ...

Activin A induces growth arrest through a SMAD- dependent pathway in hepatic progenitor cells

open access: yesCell Communication and Signaling, 2014
BackgroundActivin A, an important member of transforming growth factor-β superfamily, is reported to inhibit proliferation of mature hepatocyte. However, the effect of activin A on growth of hepatic progenitor cells is not fully understood.

Cellular Signalling Networks in High Altitude Pulmonary Hypertension: From Canonical Pathways to Emerging Targets

open access: yesCell Proliferation, EarlyView.
This review elucidates the intricate cellular signalling networks involved in high‐altitude pulmonary hypertension (HAPH), integrating canonical pathways like HIF, MAPK and BMP with emerging targets such as Wnt/β‐catenin, Notch, Hippo‐YAP and IL‐6. It highlights potential therapeutic strategies targeting these pathways to mitigate vascular remodelling ...

Activin promotes skin carcinogenesis by attraction and reprogramming of macrophages

open access: yesEMBO Molecular Medicine, 2016
Activin has emerged as an important player in different types of cancer, but the underlying mechanisms are largely unknown. We show here that activin overexpression is an early event in murine and human skin tumorigenesis. This is functionally important,

Activin A: its role and involvement in inflammatory diseases [PDF]

open access: yes, 2015
Activin proteins are members of the transforming growth factor-β family. Activin A is involved in several biological responses including wound repair, cell death, proliferation and differentiation of many cell types.

Understanding Impact of Anti‐Obesity Medications on Skeletal Muscle Mass Change Is Confounded by Measurement Methods

open access: yesObesity Reviews, EarlyView.
ABSTRACT Anti‐obesity medications promote greater degrees of weight loss than lifestyle interventions alone. There is an important need to understand whether loss of skeletal muscle during pharmacologically induced weight loss is clinically significant due to its essential role in health and disease.

Molecular pathophysiology of chronic kidney disease–mineral and bone disorder: Focus on the fibroblast growth factor 23–Klotho axis and bone turnover dynamics

open access: yesExperimental Physiology, EarlyView.
Abstract Chronic kidney disease–mineral and bone disorder (CKD‐MBD) is a major complication of chronic kidney disease (CKD), characterized by disruptions in mineral metabolism, abnormal bone turnover and vascular calcification, which collectively increase the risk of fractures and cardiovascular disease.
