Abstract

Insights

Circular RNA ABCB10 (circABCB10) promotes chronic obstructive pulmonary disease (COPD) by targeting the miR-130a/PTEN axis, driving inflammation and apoptosis. This finding offers a potential therapeutic target for COPD treatment.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Pulmonology

Background:

  • Chronic obstructive pulmonary disease (COPD) presents a significant global health challenge due to high mortality rates.
  • Effective therapeutic strategies for COPD remain urgently needed.

Purpose of the Study:

  • To investigate the role of circABCB10 in the pathogenesis of COPD.
  • To elucidate the molecular mechanism involving circABCB10, miR-130a, and PTEN in COPD development.

Main Methods:

  • Predicted the circABCB10, miR-130a, and PTEN targeting relationship using the TargetScan database.
  • Analyzed circABCB10, miR-130a, and PTEN expression in lung tissues of COPD patients and CSE-treated 16HBE cells via qRT-PCR.
  • Assessed inflammatory factors, apoptotic proteins, and cell proliferation using ELISA, Western Blot, and CCK8 assays, respectively.

Main Results:

  • CircABCB10 expression was elevated in COPD lung tissues and CSE-exposed 16HBE cells.
  • Knockdown of circABCB10 reduced CSE-induced inflammation, an effect reversed by miR-130a inhibition.
  • Overexpression of PTEN counteracted the effects of circABCB10 knockdown, modulating inflammation and apoptosis.

Conclusions:

  • CircABCB10 exacerbates inflammatory responses in COPD by targeting the miR-130a/PTEN axis.
  • The circABCB10/miR-130a/PTEN pathway represents a potential therapeutic target for managing COPD.

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

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.
