Insights

MicroRNAs (miRNAs) show abnormal levels in colorectal cancer (CRC), impacting its development and treatment. Downregulated miRNAs are promising for CRC diagnosis and targeted therapies.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • Colorectal cancer (CRC) lacks specific diagnostic and therapeutic biomarkers.
  • MicroRNAs (miRNAs) are small RNAs regulating gene expression and are implicated in CRC initiation, progression, and drug resistance.

Purpose of the Study:

  • To review the potential applications of miRNAs in colorectal cancer diagnosis, prognosis, and treatment.
  • To highlight the significance of downregulated miRNAs in CRC management.

Main Methods:

  • Literature review of studies on miRNA roles in colorectal cancer.
  • Analysis of miRNA expression patterns and their correlation with CRC characteristics.

Main Results:

  • Aberrant miRNA levels are associated with CRC initiation, progression, and drug resistance.
  • Specific miRNA expression patterns correlate with CRC diagnosis, prognosis, and therapeutic response.
  • Downregulated miRNAs show potential as diagnostic markers and therapeutic targets for CRC.

Conclusions:

  • MicroRNAs are crucial regulators of cellular mechanisms in colorectal cancer.
  • Downregulated miRNAs represent valuable candidates for CRC diagnosis and targeted tumor-suppressing therapies.

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Criticisms of the Evolutionary Perspective

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

The Behavioral Perspective on Personality01:19

The Behavioral Perspective on Personality

Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.
