Article Abstract
RNA helicase DHX33 has been identified as a critical factor promoting cancer development. In the present study, a previously developed small molecule inhibitor for DHX33, KY386, was found to robustly kill cancer cells via a new path, the ferroptosis pathway. Mechanistically, DHX33 promotes the expression of critical players in lipid metabolism including FADS1, FADS2, and SCD1 genes, thereby sensitizing cancer cells to ferroptosis mediated cell death. Our study reveals a novel mechanism of DHX33 in promoting tumorigenesis and highlights that pharmacological targeting DHX33 can be a feasible option in human cancers. Normally differentiated cells are insensitive to DHX33 inhibition, and DHX33 inhibitors have little cellular toxicity in vitro and in vivo. Our studies demonstrated that DHX33 inhibitors can be promising anticancer agents with great potential for cancer treatment.

Despite significant advancements in the treatment of non-small cell lung cancer (NSCLC) using conventional therapeutic methods, drug resistance remains a major factor contributing to disease recurrence. In this study, we aimed to explore the potential benefits of combining PI3K inhibition with Cisplatin in the context of NSCLC-derived A549 cells. Human non-small cell lung cancer A549 cells were cultured and treated with BKM120, cisplatin, or their combination.

Background: Standard treatment for glioblastoma includes chemotherapy, alkylating agents such as temozolomide (TMZ); however, MGMT resistance leads to recurrence. Demethoxycurcumin (DMC) has been reported to inhibit cancer cell growth, induce apoptosis, and prevent metastasis in different cancer models. We investigated the DMC-induced apoptosis and autophagy via inhibition of the AKT/mTOR pathway in human glioma U87MG and T98G cell lines.

The concept of the central nervous system (CNS) reserve emerged from the mismatch often observed between the extent of brain pathology and its clinical manifestations. The cognitive reserve reflects an "active" capacity, driven by the plasticity of CNS cellular components and shaped by experience, learning, and memory processes that increase resilience. We propose that neuroglial cells are central to defining this resilience and cognitive reserve.

Introduction: Trastuzumab emtansine (T-DM1), an antibody-drug conjugate, targets tumor cells overexpressing human epidermal growth factor receptor 2 (HER2). This single-arm, phase IV study assessed the safety and efficacy of T-DM1 in Indian patients with HER2-positive, locally advanced, or metastatic breast cancer previously treated with trastuzumab and a taxane.

There is growing interest in understanding the mechanisms underlying differences in cancer incidence among species (comparative oncology). The naked mole-rat (NMR) is often referenced as "cancer-resistant" and prior studies focused on identifying mechanisms explaining this. However, efforts to assess this in vivo have been limited.
