Abstract

It is widely accepted that apoptosis is closely associated with cancer cell death. However, whether autophagy induces tumor cell death has not been fully elucidated. Various studies have discussed the antitumor properties of rottlerin in human malignancies. The current study aimed to investigate the effects of rottlerin, a natural product isolated from the kamala tree (Mallotus philipensis), on growth inhibition and autophagy in gastric cancer (GC) cell lines in vitro. The results of the present study demonstrated that rottlerin suppressed cell growth, induced autophagy and apoptosis, and reduced migration and invasion in the SGC‑7901 and MGC‑803 GC cell lines. Furthermore, rottlerin led to microtubule‑associated protein 1 light chain 3β‑II augmentation and the enrichment of autophagosomes. In addition, the protein expression levels of mechanistic target of rapamycin kinase and S‑phase kinase‑associated protein 2 were downregulated in GC cells following rottlerin treatment, which is associated with autophagy. The protein levels of caspase‑3, cleaved‑caspase‑3, total poly (ADP‑ribose) polymerase (PARP) and cleaved‑PARP exhibited no marked alterations in the GC cells following rottlerin treatment, indicating that caspases were li...Continue Reading

Cell Migration in Cancer and Metastasis

Migration of cancer cells into surrounding tissue and the vasculature is an initial step in tumor metastasis. Discover the latest research on cell migration in cancer and metastasis here.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Autophagy & Disease

Autophagy is an important cellular process for normal physiology and both elevated and decreased levels of autophagy are associated with disease. Here is the latest research.

Parkinson's Disease & Autophagy (MDS)

Autophagy leads to degradation of damaged proteins and organelles by the lysosome. Impaired autophagy has been implicated in several diseases. Here is the role of autophagy in Parkinson’s disease.

Autophagosome

An autophagosome is the formation of double-membrane vesicles that involve numerous proteins and cytoplasmic components. These double-membrane vesicles are then terminated at the lysosome where they are degraded. Discover the latest research on autophagosomes here.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Autophagy & Metabolism

Autophagy preserves the health of cells and tissues by replacing outdated and damaged cellular components with fresh ones. In starvation, it provides an internal source of nutrients for energy generation and, thus, survival. A powerful promoter of metabolic homeostasis at both the cellular and whole-animal level, autophagy prevents degenerative diseases. It does have a downside, however--cancer cells exploit it to survive in nutrient-poor tumors.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Autophagy & Model Organisms

Autophagy is a cellular process that allows degradation by the lysosome of cytoplasmic components such as proteins or organelles. Here is the latest research on autophagy & model organisms

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.

Autophagosome
