Apoptosis01:30

Apoptosis

13.9K
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

Glaucoma: Overview01:25

Glaucoma: Overview

1.2K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

8.2K
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...

Overview of Cell Death01:30

Overview of Cell Death

9.3K
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

4.3K
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

8.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Area of Science:

  • Ophthalmology
  • Developmental Biology
  • Cell Biology

Background:

  • The ocular lens provides a unique system for studying programmed cell death (apoptosis).
  • Lens development involves cell proliferation, migration, and apoptosis.
  • Lens epithelial cells differentiate into fiber cells using regulators common to apoptosis signaling.

Purpose of the Study:

  • To review current knowledge on apoptosis in the ocular lens.
  • To emphasize the role of apoptosis in lens development and pathology.

Main Methods:

  • Review of existing literature on ocular lens apoptosis.
  • Analysis of studies involving gene manipulation (exogenous or knock-out) in the ocular lens.
  • Examination of in vitro and in vivo studies on stress-induced apoptosis in adult lenses.

Main Results:

  • Apoptosis is integral to normal ocular lens development.
  • Genetic alterations in the lens lead to apoptosis and subsequent lens abnormalities.
  • Stress-induced apoptosis in adult lenses contributes to cataractogenesis.

Conclusions:

  • Apoptosis is a critical process in both the development and pathology of the ocular lens.
  • Understanding lens apoptosis is vital for addressing developmental defects and cataract formation.
