Abnormal Proliferation

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...

Negative Regulator Molecules

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

The Retinoblastoma Gene

The Retinoblastoma Gene

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.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Necrosis

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...

NF-κB-dependent Signaling Pathway

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.

Background:

Lung adenocarcinoma (LUAD) is a major cause of cancer mortality.
Understanding LUAD progression mechanisms is crucial for developing effective treatments.

Purpose of the Study:

To investigate the role of Ring Finger Protein 216 (RNF216) in LUAD progression.
To explore RNF216's impact on ferroptosis and its underlying mechanisms.

Main Methods:

Assessed RNF216 expression in LUAD tissues and cell lines.
Conducted in vitro functional assays (viability, migration, invasion, ferroptosis).
Performed mechanistic studies on p53 ubiquitination and stability; utilized in vivo xenograft models.

Main Results:

RNF216 is overexpressed in LUAD.
RNF216 silencing inhibited LUAD cell proliferation, migration, and invasion.
RNF216 knockdown promoted ferroptosis by stabilizing p53 via reduced ubiquitination, confirmed in vivo.

Conclusions:

RNF216 promotes LUAD progression by suppressing ferroptosis through p53 ubiquitination.
Targeting RNF216 could be a novel therapeutic strategy to induce ferroptosis in LUAD.
