What is Monogastric Digestion?01:50

What is Monogastric Digestion?

70.5K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Tumor Progression02:07

Tumor Progression

6.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Neural Regulation01:37

Neural Regulation

39.1K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Protein Modifications in the RER01:26

Protein Modifications in the RER

5.0K
Modification of secretory and transmembrane proteins entering the rough ER begins in the ER lumen. These modifications aid in protein folding and stabilize the acquired tertiary structure. Protein modifications in the rough ER co-occur at different stages of protein folding.
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal...

Mutagenicity and Carcinogenicity01:25

Mutagenicity and Carcinogenicity

1.2K
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • Gastrointestinal tumors (e.g., colorectal, liver) are leading causes of cancer death with poor prognoses.
  • Traditional treatments are often insufficient for these prevalent malignancies.
  • Recent advances reveal RNA chemical alterations are key in cancer development.

Purpose of the Study:

  • To explore epigenetic RNA modifications in gastrointestinal cancers.
  • To detail the roles of "Writers," "Readers," and "Erasers" in RNA modification.
  • To review detection methodologies and therapeutic implications.

Main Methods:

  • Review of current literature on RNA modifications and gastrointestinal oncology.
  • Discussion of epigenetic RNA alterations including N6-methyladenosine (m6A), 5-methylcytosine (m5C), 1-methyladenosine (m1A), 7-methylguanosine (m7G), and N4-acetylcysteine (ac4C).
  • Overview of detection techniques: conventional (e.g., mass spectrometry) and specialized (e.g., bisulfite sequencing).

Main Results:

  • RNA modifications are significantly implicated in the pathogenesis of gastrointestinal tumors.
  • Regulatory proteins ("Writers," "Readers," "Erasers") control these modifications.
  • Various methods exist for detecting these crucial RNA alterations.

Conclusions:

  • RNA modifications are vital in the development, progression, and treatment of gastrointestinal cancers.
  • Targeting these epigenetic changes offers potential for improved diagnostics and therapeutics.
  • Further research can enhance accuracy, efficacy, and prognosis in gastrointestinal oncology.
