Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

MET and NF2 alterations confer primary and early resistance to first‐line alectinib treatment in ALK‐positive non‐small‐cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Alectinib resistance in ALK+ NSCLC depends on treatment sequence and EML4‐ALK variants. Variant 1 exhibited off‐target resistance after first‐line treatment, while variant 3 and later lines favored on‐target mutations. Early resistance involved off‐target alterations, like MET and NF2, while on‐target mutations emerged with prolonged therapy.

Neuropathological and Behavioral Consequences of Adeno-Associated Viral Vector-Mediated Continuous Intrastriatal Neurotrophin Delivery in a Focal Ischemia Model in Rats

open access: yesNeurobiology of Disease, 2002
Nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) were continuously delivered to the striatum at biologically active levels via recombinant adeno-associated viral (rAAV) gene transfer 4–5 weeks prior to 30 min of middle cerebral ...

CDK5 interacts with MST2 and modulates the Hippo signalling pathway

open access: yesFEBS Open Bio, Volume 15, Issue 4, Page 647-660, April 2025.
By using a yeast‐two‐hybrid system, immune precipitation and a proteomics approach, we identify a novel interaction between CDK5 and MST2, which modulates the mechano‐sensitive Hippo signalling pathway in a liver tumour cell line. MST2 (STK3) is a major upstream kinase in the Hippo signalling pathway, an evolutionary conserved pathway in regulation of ...

The nuclear events guiding successful nerve regeneration

open access: yesFrontiers in Molecular Neuroscience, 2011
Peripheral nervous system (PNS) neurons survive and regenerate after nerve injury, whereas central nervous system (CNS) neurons lack the capacity to do so.

Hydrogen peroxide induced by nerve injury promotes axon regeneration via connective tissue growth factor

open access: yesActa Neuropathologica Communications, 2022
Regeneration of the neuromuscular junction (NMJ) leverages on extensive exchange of factors released from motor axon terminals (MATs), muscle fibers and perisynaptic Schwann cells (PSCs), among which hydrogen peroxide (H2O2) is a major pro-regenerative ...

Tumor-induced neoneurogenesis and perineural tumor growth: a mathematical approach [PDF]

open access: yesarXiv, 2015
Primary tumors infrequently lead to demise of cancer patients; instead, mortality and a significant degree of morbidity result from the growth of secondary tumors in distant organs (metastasis). It is well-known that malignant tumors induce the formation of a lymphatic and a blood vascular network around themselves.

Pharmacological effects of osimertinib on a chicken chorioallantoic membrane xenograft model with the EGFR exon‐19‐deleted advanced NSCLC mutation

open access: yesFEBS Open Bio, Volume 15, Issue 5, Page 836-855, May 2025.
Osimertinib reduces angiogenesis and PDL1 expression in in ovo tumors, transforming them into ‘cold tumors’ with lower immune activity. Anatomopathological and transcriptomic analyses highlight its therapeutic impact on tumor biology. This study underscores osimertinib's potential to reshape the tumor microenvironment and provides insights into its ...

Influence of the complex drug Cocarnit on the sciatic nerve in the development of diabetic polyneuropathy in rats

open access: yesCurrent Issues in Pharmacy and Medical Sciences, 2020
Ulcers and slow wound healing are common in diabetic polyneuropathy (DP), as well as shooting or burning pain, sensitivity to touch or lack of sensitivity, low oxygenation of nerve tissue, conductivity disorders and various vascular disorders.

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

open access: yesFEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.
