Published: March 31, 2022

Cancer is a leading cause of death worldwide. In many cases, the treatment disease limited due to metastasis cells distant locations body through blood and lymphatic drainage. Most anticancer therapeutic options focus mainly on inhibition tumor cell growth or induction death, do not consider molecular basis metastasis. The aim this work provide comprehensive review focusing cancer mitogen-activated protein kinase (MAPK) pathway (ERK/JNK/P38 signaling) as crucial modulator process.

Published: Feb. 12, 2024

Abstract Cancer treatment faces many hurdles and resistance is one among them. Anti-cancer strategies are evolving due to innate acquired capacity, governed by genetic, epigenetic, proteomic, metabolic, or microenvironmental cues that ultimately enable selected cancer cells survive progress under unfavorable conditions. Although the mechanism of drug being widely studied generate new target-based drugs with better potency than existing ones. However, broader flexibility in resistance, advanced therapeutic options efficacy need be explored. Combination therapy an alternative a success rate though risk amplified side effects commonplace. Moreover, recent groundbreaking precision immune ways overcome has revolutionized anticancer greater extent only limitation individual-specific needs further attention. This review will focus on challenges opted withstand current therapies at molecular level also highlights emerging -like immunological, stem cell-based may prove have potential challenge problem resistance.

Cancer cell cycle heterogeneity as a critical determinant of therapeutic resistance

Genes & Diseases, Journal Year: 2023, Volume and Issue: 11(1), P. 189 - 204

Published: Jan. 14, 2023

Intra-tumor heterogeneity is now arguably one of the most-studied topics in tumor biology, as it represents a major obstacle to effective cancer treatment. Since cells are highly diverse at genetic, epigenetic, and phenotypic levels, intra-tumor can be assumed an important contributing factor nullification chemotherapeutic effects, recurrence tumor. Based on role heterogeneous subpopulations with varying cell-cycle dynamics behavior during progression treatment; herein, we aim establish comprehensive definition for adaptation neoplastic against therapy. We discuss two parallel yet distinct that play pivotal roles reducing effects chemotherapy: "resistant" "tolerant" populations. Furthermore, this review also highlights impact quiescent phase cell cycle survival mechanism cells. Beyond understanding mechanisms underlying quiescence, provides insightful perspective stem (CSCs) their dual intertwined functions based state response Moreover, CSCs, epithelial–mesenchymal transformed cells, circulating (CTCs), disseminated (DTCs), which mostly proved have multiple biological links implicated our viewpoint tumors.

Metabolic reprogramming and therapeutic resistance in primary and metastatic breast cancer

Molecular Cancer, Journal Year: 2024, Volume and Issue: 23(1)

Published: Nov. 21, 2024

Metabolic alterations, a hallmark of cancer, enable tumor cells to adapt their environment by modulating glucose, lipid, and amino acid metabolism, which fuels rapid growth contributes treatment resistance. In primary breast metabolic shifts such as the Warburg effect enhanced lipid synthesis are closely linked chemotherapy failure. Similarly, metastatic lesions often display distinct profiles that not only sustain but also confer resistance targeted therapies immunotherapies. The review emphasizes two major aspects: mechanisms driving in both how unique environments sites further complicate treatment. By targeting vulnerabilities at stages, new strategies could improve efficacy existing provide better outcomes for cancer patients.

Oxidative Stress and Redox Imbalance: Common Mechanisms in Cancer Stem Cells and Neurodegenerative Diseases

Cells, Journal Year: 2025, Volume and Issue: 14(7), P. 511 - 511

Published: March 29, 2025

Oxidative stress (OS) is an established hallmark of cancer and neurodegenerative disorders (NDDs), which contributes to genomic instability neuronal loss. This review explores the contrasting role OS in stem cells (CSCs) NDDs. Elevated levels reactive oxygen species (ROS) contribute promote tumor initiation progression CSCs, while NDDs such as Alzheimer’s Parkinson’s disease, accelerates death impairs cellular repair mechanisms. Both scenarios involve disruption delicate balance between pro-oxidant antioxidant systems, leads chronic oxidative stress. Notably, CSCs neurons display alterations redox-sensitive signaling pathways, including Nrf2 NF-κB, influence cell survival, proliferation, differentiation. Mitochondrial dynamics further illustrate these differences: enhanced function supports adaptability whereas impairments heighten vulnerability. Understanding common mechanisms OS-induced redox imbalance may provide insights for developing interventions, addressing aging hallmarks, potentially mitigating or preventing both
