Overview of Cell Death01:30

Overview of Cell Death

9.5K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Autophagic Cell Death01:18

Autophagic Cell Death

4.4K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Gallbladder01:17

Gallbladder

2.0K
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

Diseases of the Liver and Gallbladder

1.9K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Induced Pluripotent Stem Cells01:13

Induced Pluripotent Stem Cells

27.3K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

3.2K
Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Area of Science:

  • Inorganic Chemistry
  • Cancer Biology
  • Medicinal Chemistry

Background:

  • Gallbladder cancer (GBC) remains a significant health challenge with limited effective treatments.
  • Development of novel therapeutic agents is crucial for improving patient outcomes.

Purpose of the Study:

  • To synthesize and evaluate a new ruthenium complex, Ru-UCN3, for its anticancer activity.
  • To investigate the mechanism of action of Ru-UCN3 in gallbladder cancer cells.

Main Methods:

  • Synthesis of novel ruthenium complexes.
  • In vitro evaluation of antiproliferative, cytotoxic, and apoptosis-inducing activities using the ApoTox-Glo assay.
  • Quantitative real-time PCR (q-PCR) to assess the transcription levels of apoptosis-related genes.

Main Results:

  • Ru-UCN3 demonstrated significant inhibition of GBC cell proliferation (G-415 cell line).
  • Apoptosis induction was confirmed by the upregulation of pro-apoptotic genes (Puma, Diablo, Caspase-9) and downregulation of anti-apoptotic genes (Bcl-xL, Bcl-2).
  • Increased caspase 3/7 activity was observed 24 hours post-exposure to Ru-UCN3.

Conclusions:

  • The synthesized ruthenium complexes, particularly Ru-UCN3, exhibit inhibitory effects on GBC cells.
  • Ru-UCN3 represents a promising candidate for further investigation as an anticancer agent.
  • Further in vitro and in vivo studies, along with chemical modifications, are warranted to explore its therapeutic potential.
