Insights

Mitotic Spindle Positioning (MISP) inhibits ferroptosis in non-small cell lung cancer (NSCLC) by activating YAP. Blocking MISP sensitizes NSCLC cells to ferroptosis, offering a new therapeutic strategy.

Area of Science:

  • Oncology
  • Cell Biology
  • Molecular Mechanisms

Background:

  • Non-small cell lung cancer (NSCLC) therapy faces challenges due to treatment resistance.
  • Ferroptosis, a regulated cell death, influences NSCLC progression and therapy response.
  • The Hippo pathway's role in ferroptosis is emerging but not fully elucidated in NSCLC.

Purpose of the Study:

  • To identify novel regulators of ferroptosis in NSCLC.
  • To investigate the role of the Hippo pathway in NSCLC ferroptosis.
  • To explore potential therapeutic targets for overcoming NSCLC resistance.

Main Methods:

  • Analysis of Mitotic Spindle Positioning (MISP) expression in NSCLC tissues.
  • In vitro and in vivo studies assessing the impact of MISP on ferroptosis and cell proliferation.
  • Biochemical assays to determine the interaction between MISP, MST1/2 kinases, and YAP.
  • Investigation of the feedback loop between MISP and YAP signaling.

Main Results:

  • MISP is upregulated in NSCLC and inhibits ferroptosis.
  • Loss of MISP sensitizes NSCLC cells to ferroptosis, reducing proliferation.
  • MISP binds MST1/2, inhibiting Hippo signaling and promoting YAP activation.
  • YAP activation upregulates SLC7A11, conferring ferroptosis resistance.
  • A MISP-YAP feedback loop amplifies YAP signaling.

Conclusions:

  • MISP acts as a critical ferroptosis inhibitor in NSCLC via the MISP-YAP axis.
  • Targeting MISP could be a therapeutic strategy for NSCLC, particularly in YAP-dysregulated cases.
  • Understanding the MISP-YAP-ferroptosis interplay offers new avenues for NSCLC treatment.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

The Unfolded Protein Response01:37

The Unfolded Protein Response

The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...
