Insights

NSC48160 suppresses KRAS in hepatocellular carcinoma (HCC), inducing cell death via ferroptosis. This novel KRAS inhibitor reprograms metabolism and redox balance, offering a promising therapeutic strategy for KRAS-driven HCC.

Area of Science:

  • Oncology
  • Molecular Biology
  • Metabolic Pathways

Background:

  • Oncogenic KRAS drives cancer progression and is a therapeutic challenge.
  • KRAS overexpression in hepatocellular carcinoma (HCC) correlates with tumor aggressiveness.

Purpose of the Study:

  • To investigate NSC48160 as a novel therapeutic agent for KRAS-driven HCC.
  • To elucidate the mechanism by which NSC48160 induces HCC cell death.

Main Methods:

  • Metabolomic profiling to analyze metabolic changes induced by NSC48160.
  • Ferroptosis-pathway array assays to investigate the Nrf2-SLC7A11-GPX4 axis.
  • In vitro and in vivo studies combining NSC48160 with SLC7A11 inhibitor HG106.

Main Results:

  • NSC48160 suppresses KRAS expression, leading to HCC cell death.
  • NSC48160 enhances tricarboxylic acid (TCA) cycle and fructose metabolism, disrupting redox homeostasis and triggering ferroptosis.
  • NSC48160 downregulates Nrf2 expression, inhibiting downstream targets GPX4 and SLC7A11, and promoting ferroptosis.
  • Combination therapy with NSC48160 and HG106 synergistically eliminated HCC cells and suppressed tumor growth.

Conclusions:

  • NSC48160 is a novel KRAS inhibitor that induces ferroptosis in HCC through metabolic and redox reprogramming.
  • The combination of NSC48160 and HG106 presents a promising therapeutic strategy for KRAS-driven HCC.

Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

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.

Liver Regeneration01:24

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...
