Aberrant signaling in myeloproliferative neoplasms may arise from alterations in genes coding for signal transduction proteins or epigenetic regulators. Both mutated and normal cells cooperate, altering fragile balances in bone marrow niches and fueling persistent inflammation through paracrine or systemic signals. Despite the hopes placed in targeted therapies, myeloid proliferative neoplasms remain incurable diseases in patients not eligible for stem cell transplantation. Due to the emergence of drug resistance, patient management is often very difficult in the long term. Unexpected connections among signal transduction pathways highlighted in neoplastic cells suggest new strategies to overcome neoplastic cell adaptation.

Background: Lately, significant attention has been drawn towards the potential efficacy of cholera toxin (CT)-an exotoxin produced by the small intestine pathogenic bacterium Vibrio cholera-in modulating cancer-promoting events. In a recent study, we demonstrated that early-life oral administration of non-pathogenic doses of CT in mice suppressed chemically-induced carcinogenesis in tissues distantly located from the gut. In the mammary gland, CT pretreatment was shown to reduce tumor multiplicity, increase apoptosis and alter the expression of several cancer-related molecules.

In this study, we determined the frequency of secondary lesions in 28 iAMP21 BCP-ALL patient samples and investigated cellular sensitivity for candidate-targeted drugs. iAMP21 was enriched in aberrations (10.

Background: In approximately 80% of colorectal cancer cases, mutations in the adenomatous polyposis coli () gene disrupt the Wingless-related integration site (Wnt)/β-catenin signaling pathway, a crucial factor in carcinogenesis. This disruption may result in consequences such as aberrant spindle segregation and mitotic catastrophe. This study aimed to analyze the effectiveness of the ethanolic extract of red okra () pods (EEROP) in inducing apoptosis in colorectal cancer cells (SW480) by inhibiting the Wnt/β-catenin signaling pathway.

Hydrocephalus is a neurological condition caused by aberrant circulation and/or obstructed cerebrospinal fluid (CSF) flow after cerebral ventricle abnormal dilatation. In the past 50 years, the diagnosis and treatment of hydrocephalus have remained understudied and underreported, and little progress has been made with respect to prevention or treatment. Further research on the pathogenesis of hydrocephalus is essential for developing new diagnostic, preventive, and therapeutic strategies.

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological disease originating from the malignant transformation of T-cell progenitors, caused by the accumulation of genetic aberrations. One-fifth of T-ALL patients are characterized by ectopic expression of the homeobox transcription factor TLX3. However, the role of TLX3 in T-ALL remains elusive, partly due to the lack of suitable study models.
