PKB and the Mitochondria: AKTing on Apoptosis

Words: 574 Pages: 2 5329

Function and Structure of PKB PKB contains three isoforms with catalytic domains similar to those in the AGC kinase family. PKB, initially discovered through homology cloning, maintained a similar appearance to protein kinase A and C in its kinase domain, and therefore, was named as Protein Kinase B (PKB). It has two family members: PKB/c-Akt2 (c-Akt is a cellular homologue of PKB) which is expressed mainly in insulin-target tissues, and PKB/c-Akt3 which is highly expressed in the brain and testis […]

The Vital Role of Apoptosis in Developmental Biology

Words: 1030 Pages: 3 5597

Apoptosis, a fundamental cellular process, enables cells to undergo programmed and organized death. Introduction This form of programmed cell death, or PCD, is indispensable for maintaining the stability and equilibrium of living organisms. It is a universal process observed across both vertebrates and invertebrates (Miguel-Aliaga et al., 2009). Understanding "normal" development often involves comparing it against what is considered abnormal, given that PCD has a distinguishable relationship with cell division and differentiation. When these processes fall out of balance, developmental […]

Intracellular Role of Apoptosis in In-Vivo Reactions Occurring in Multi-Cellular Organisms

Words: 1944 Pages: 6 5131

There are two well-known methods of cell execution: Apoptosis and Necrosis. Necrosis is regarded as a violent form of cell death, whereas apoptosis, on the other hand, is a more benign, modulated, and rational mode of killing cells. This process involves making well-informed decisions about selected cells to be terminated for the greater good of the host organisms. The advantages associated with the use of apoptosis as a regulated manner of programmed cell execution are well documented in literature. These […]

How Cells Cheat Death

Words: 633 Pages: 2 5934

Cells are constantly fighting between life and death. It is believed that once cells go through certain incidences, their death is irreversible. Incidences such as, shrinkage, the breakdown of DNA or mitochondria, condensation of the nucleus, as well as activation of caspases. A new ability to replenished cells was recently discovered; it is called anastasis. Anastasis is a natural cell recovery that rescues cells from the brink of death (Tang, 2018). Its purpose is to save cells that are challenging […]

It is expected that cancer risk would increase with body size and life span. Peto’s paradox describes the lack of correlation between body size, life span, and cancer risk (Caulin, 2011). The cellular mechanism behind this has only been experimentally demonstrated in rodents. TP53 is a gene that codes for the p53 protein. This gene is vital in tumor suppression, and is mutated in many human cancers (Jiang, 2018). Humans have one copy (2 alleles) of this gene. Both alleles […]

The Tumor Suppressor Role of TAp73 in Two Types of Cancer

Transcription factor of p53 initiates apoptosis after receiving information about metabolic disorder or genetic damage, thus playing a critical role as tumor suppressor. p73 is a cousin of p53, shares lots of similarities with p53 including gene structure and amino acid level. Therefore, p73 is able to activate some p53 target genes by binding to p53-responsive elements when p53 is impaired. Also, p73 is rarely mutant compared to p53 in tumor cells. Whether p73 plays a role in tumor suppressor […]

The Role of Senescent Cells in Ageing and Cancer Suppression

Words: 1175 Pages: 4 6341

Senescent cells, often termed as "zombie cells," are somatic cells that, although no longer capable of dividing, display resistance to apoptosis, the process of programmed cell death (Scudellari, 2017). These cells accumulate in various body parts, exhibiting unique resistance to apoptosis, expressing distinct extracellular proteins, and secreting diverse molecules, including cytokines (Scudellari, 2017). This secretory activity is known as the cell's senescence-associated secretory phenotype (SASP). The presence of zombie cells and their SASPs can lead to various outcomes (Coppé, Desprez, […]

All living cells will eventually decay and die. There are two recognized types of cell death: apoptosis and necrosis. Apoptosis refers to the “self-destruction” of a cell by its own mechanisms. Typically, a cell will undergo apoptosis when it is no longer able to repair itself. This could result from a number of possible cell injuries including viral infection, mutation, protein dysfunction, and DNA damage by way of free radicals. Apoptosis is implemented by enzymes called caspases, which have the […]

Cyclic GMP-AMP Synthase

Words: 385 Pages: 1 5129

Genomic DNA can be damaged by endogenous or environmental stresses. During repair, these short single-stranded DNAs are continuously generated and may leak out to the cytoplasm, where they are generally drawn back into the nucleus by DNA repair and replication factors (RPA and Rad51). Alongside this, TREX1, a cytoplasmic exonuclease, is anchored on the outer nuclear membrane to degrade leaking DNAs immediately. This prevents activation of the cGAS/STING pathway against self DNA. Inhibition of any of the above-mentioned proteins leads […]

Specifically, these tumors are diffuse astrocytomas meaning that the tumor develops from astroglial cells of the brain stem. This tumor accounts for about 10%-20% of all brain tumors in children and roughly 80% of the 300-400 pediatric brainstem tumors that are diagnosed each year. The majority of children who develop this tumor type are […]

Diosgenin in Colon Cancer

Words: 878 Pages: 3 5477

The author noted that diosgenin constrains the 3-hydroxy-3-methylglutaryl CoA reductase expression and stimulates apoptosis in human colon tumor cells. Diosgenin is also a potent inhibitor of HCT-116 with growth inhibition and induction of apoptosis [39]. Diosgenin induces apoptosis via the cyclooxygenase-2 and 5-lipoxygenase pathways in HT-29 and HCT-116 [40]. The author described diosgenin's ability to enhance 5-LOX activity; its inhibition by AA-861 notably reduces the apoptosis of colorectal tumor cells. Moreover, colorectal carcinoma cells expressing COX-2 are less sensitive to […]
