Triple-negative breast cancer (TNBC) is a heterogeneous, aggressive phenotype of with associated chemoresistance. The development chemo- or radioresistance could be attributed to diverse tumor microenvironments, overexpression membrane proteins (transporters), epigenetic changes, and alteration the cell signaling pathways/genes stem cells (CSCs). Due heterogeneous nature TNBC, therapeutic response existing modalities offers limited scope thus results in reccurance after therapy. To establish landmark efficacy, number novel have been proposed. In addition, reversal resistance that developed during treatment may altered by employing appropriate modalities. This review aims discuss plethora investigations carried out, which will help readers understand make an choice therapy directed toward complete elimination TNBC. manuscript addresses major contributory factors from microenvironment are responsible for chemoresistance poor prognosis. cellular events molecular mechanism-based interventions explained detail.

TNBC progression, invasion, metastasis recurrence can also inhibited blocking multiple pathways, targeting specific receptors/epigenetic targets, disrupting bioenergetics generating reactive oxygen species (ROS).

Опубликована: Фев. 11, 2025

Abstract Cancer recurrence, driven by the phenomenon of tumor dormancy, presents a formidable challenge in oncology. Dormant cancer cells have ability to evade detection and treatment, leading relapse. This review emphasizes urgent need comprehend dormancy its implications for recurrence. Despite notable advancements, significant gaps remain our understanding mechanisms underlying lack reliable biomarkers predicting provides comprehensive analysis cellular, angiogenic, immunological aspects dormancy. It highlights current therapeutic strategies targeting dormant cells, particularly combination therapies immunotherapies, which hold promise preventing By elucidating these proposing innovative research methodologies, this aims deepen ultimately facilitating development more effective recurrence improving patient outcomes.

The Golgi-sialyltransferase ST6Gal1 (βgalactosidase α2,6 sialyltransferase 1), adds the negatively charged sugar, sialic acid, to terminal galactose of N-glycosylated proteins. Upregulation is observed in many malignancies, and a large body research has determined that ST6Gal1-mediated sialylation impacts cancer hallmarks. affects oncogenic behaviors including sustained proliferation, enhanced self-renewal, epithelial-to-mesenchymal transition, invasion, chemoresistance. However, there are relatively few ST6GaL1 related signaling pathways well-established mediate these biologies: greater delineation specific targets mechanisms orchestrated by needed. aim this review provide summary our current understanding select affected ST6Gal1.

A spotlight on the interplay between Wnt/β-catenin signaling and circular RNAs in hepatocellular carcinoma progression

Frontiers in Oncology, Год журнала: 2023, Номер 13

Опубликована: Июль 21, 2023

Hepatocellular carcinoma (HCC) is one of the deadliest cancers due to multifocal development and distant metastasis resulting from late diagnosis. Consequently, new approaches HCC diagnosis treatment are required reduce mortality rates. A large body evidence suggests that non-coding RNAs (ncRNAs) important in cancer initiation progression. Cancer cells release many these ncRNAs into blood or urine, enabling their use as a diagnostic tool. Circular (CircRNAs) members regulate cell expansion, migration, metastasis, chemoresistance through different mechanisms such Wnt/β-catenin Signaling pathway. The pathway plays prominent roles several biological processes including organogenesis, stem regeneration, survival. Aberrant signaling both pathways mentioned above could affect progression cancers, HCC. Based on studies investigated current review, circRNAs have an effect formation by sponging miRNAs RNA-binding proteins (RBPs) regulating Therefore, circRNAs/miRNAs RBPs/Wnt/β-catenin be considered promising prognostic therapeutic targets

The interaction of Notch and Wnt signaling pathways in vertebrate regeneration

Cell Regeneration, Год журнала: 2021, Номер 10(1)

Опубликована: Апрель 1, 2021

Abstract Regeneration is an evolutionarily conserved process in animal kingdoms, however, the regenerative capacities differ from species and organ/tissues. Mammals possess very limited potential to replace damaged organs, whereas non-mammalian usually have impressive abilities regenerate organs. The regeneration requires proper spatiotemporal regulation key signaling pathways. canonical Notch Wnt pathways, two fundamental signals guiding development, been demonstrated play significant roles of vertebrates. In recent years, increasing evidence has implicated cross-talking between during organ regeneration. this review, we summarize several representative events, emphasizing functions molecular bases their interplay these processes, shedding light on utilizing pathways enhance mammals design legitimate therapeutic strategies.

Опубликована: Май 23, 2024

Glioblastoma Multiforme (GBM) is an aggressive brain tumor with a high mortality rate. Direct reprogramming of glial cells to different cell lineages, such as induced neural stem (iNSCs) and neurons (iNeurons), provides genetic tools manipulate cell’s fate potential therapy for neurological diseases. NeuroD1 (ND1) master transcriptional factor neurogenesis it promotes neuronal differentiation. In the present study, we tested hypothesis that expression ND1 in GBM can force them differentiate toward post-mitotic halt progression. cultured human lines, including LN229, U87, U373 temozolomide (TMZ)-sensitive T98G TMZ-resistant cells, lineage conversion was by adeno-associated virus (AAV) package carrying ND1. Twenty-one days after AAV-ND1 transduction, ND1-expressing displayed markers MAP2, TUJ1, NeuN. The ND1-induced transdifferentiation regulated Wnt signaling markedly enhanced under hypoxic condition (2% O2 vs. 21% O2). cultures had fewer BrdU-positive proliferating compared vector control cultures. Increased death visualized TUNEL staining, reduced migrative activity demonstrated wound-healing test both TMZ-sensitive -resistant cells. striking contrast cancer converted expressed anti-tumor gene p53. orthotopical mouse model, AAV-ND1-reprogrammed were transplanted into fornix cyclosporine-immunocompromised C57BL/6 brain. Compared cell-formed tumors, from ND1-reprogrammed formed smaller tumors TUJ1 Thus, using single-factor overcame drug resistance, converting malignant heterogeneous normal neuron-like vitro vivo. These novel observations warrant further research patient-derived xenograft (PDX) models potentially effective treatment deadly likely other astrocytoma tumors.
