Summary

This summary is machine-generated.

Nuciferine (NF) effectively suppresses hepatocellular carcinoma (HCC) proliferation by halting the cell cycle and promoting apoptosis. This natural compound targets the HER2-AKT/ERK1/2 pathway, offering a potential therapeutic strategy for HCC.

Area Of Science

  • Oncology
  • Pharmacology
  • Biochemistry

Background

  • Hepatocellular carcinoma (HCC) presents a significant global health challenge with high morbidity and mortality rates.
  • Nuciferine (NF), an alkaloid from Nelumbo nucifera, exhibits antineoplastic properties, but its specific role in HCC remains under investigation.

Purpose Of The Study

  • To investigate the antiproliferative effects and underlying mechanisms of Nuciferine (NF) in hepatocellular carcinoma (HCC).
  • To evaluate the efficacy of NF in inhibiting HCC cell growth and inducing apoptosis, both in vitro and in vivo.

Main Methods

  • MTT assays and colony formation assays were used to assess antiproliferative effects.
  • Flow cytometry (PI/RNase and Annexin V-FITC/PI staining) evaluated cell cycle arrest and apoptosis.
  • In vivo studies utilized ultrasonic imaging and histopathology in xenograft models.
  • RNA sequencing (RNA-seq), bioinformatics, and qRT-PCR analysis elucidated the molecular mechanisms.

Main Results

  • NF demonstrated significant antiproliferative activity against HCC cells, inducing cell cycle arrest at the G2 phase.
  • NF treatment led to a concentration-dependent increase in apoptosis in HCC cells.
  • In vivo studies confirmed NF's tumor-suppressive capacity.
  • NF was found to inhibit the HER2-AKT/ERK1/2 signaling pathway.

Conclusions

  • Nuciferine (NF) effectively suppresses hepatocellular carcinoma (HCC) proliferation and induces apoptosis.
  • NF's mechanism involves cell cycle arrest at G2 phase and inhibition of the HER2-AKT/ERK1/2 signaling pathway.
  • NF represents a promising therapeutic agent for hepatocellular carcinoma (HCC).

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

Mitogens and the Cell Cycle 02:38

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Inhibition of Cdk Activity 02:34

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

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.
