What is Natural Selection?

126.4K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Nature and Nurture

22.2K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Position and Displacement01:31

Position and Displacement

25.1K
The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...

Serial Position Effect01:03

Serial Position Effect

538
The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

Area of Science:

  • Oncology
  • Hematology
  • Genetics

Background:

  • Extranodal natural killer/T-cell lymphoma, nasal type (ENKL) is a rare, aggressive Non-Hodgkin lymphoma.
  • ENKL is strongly associated with Epstein-Barr virus infection and prevalent in Asia and Latin America.
  • Current standard treatments for ENKL are not fully established, necessitating further research.

Purpose of the Study:

  • To review genetic alterations in ENKL and their implications for therapeutic targets.
  • To highlight recent findings on biologic markers and novel therapeutic strategies for ENKL.
  • To provide insights into the mechanisms and potential treatments for ENKL.

Main Methods:

  • Review of gene expression profiling and sequencing techniques to identify genetic alterations.
  • Analysis of existing literature on ENKL pathogenesis, treatment, and outcomes.
  • Synthesis of information on genetic mutations, epigenetic dysregulation, and therapeutic approaches.

Main Results:

  • Frequent deletion of chromosome 6q21 silences tumor suppressor genes in ENKL.
  • Novel mutations activate oncogenic pathways like JAK/STAT, NF-κB, and MAPK.
  • Non-anthracycline regimens and anti-PD-1 antibodies show promise for advanced/refractory ENKL.

Conclusions:

  • Genetic alterations and epigenetic dysregulation are key to ENKL pathogenesis.
  • Targeting these alterations and pathways may lead to novel therapeutic strategies.
  • Optimizing combined radiotherapy and chemotherapy, and identifying superior non-anthracycline regimens are ongoing research priorities.
