Proofreading

9.4K
Synthesis of new DNA molecules is carried out by the enzyme DNA polymerase, which adds nucleotides on the daughter strand complementary to the template DNA strand. DNA polymerase has a higher affinity to add the correct base and ensures fidelity during DNA replication. Furthermore,  it exhibits proofreading activity during replication, using an exonuclease domain that cuts off incorrect nucleotides from the nascent DNA strand.

Clot Retraction and Fibrinolysis01:16

Clot Retraction and Fibrinolysis

9.8K
After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.

Mismatch Repair

6.8K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

Repressible Operon: trp Operon

2.2K
The trp operon in Escherichia coli exemplifies a repressible operon. It regulates the synthesis of tryptophan through repressor-mediated transcriptional control and attenuation. This dual regulatory mechanism ensures tryptophan biosynthesis occurs only when needed, conserving cellular resources.Structure of the trp OperonThe trp operon consists of five structural genes (trpE, trpD, trpC, trpB, and trpA) that encode enzymes for tryptophan biosynthesis. These genes are transcribed as a single...

Summary

MicroRNA-148a (miR-148a) suppresses ovarian cancer progression by inhibiting cell proliferation and invasion. It targets TGF-β-induced 2 (TGFI2), suggesting the miR-148a/TGFI2 pathway is crucial in ovarian cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Ovarian cancer (OC) is a leading gynecological malignancy.
  • MicroRNAs (miRs) are implicated in OC development and progression.
  • The specific roles and mechanisms of miRs in OC require further elucidation.

Purpose of the Study:

  • To investigate the regulatory role of miR-148a in ovarian cancer cell proliferation and invasion.
  • To identify the molecular targets and pathways affected by miR-148a in OC.

Main Methods:

  • Analysis of miR-148a expression in OC tissues and cell lines.
  • Overexpression of miR-148a in OC cells to assess effects on proliferation and invasion.
  • Identification and validation of TGFI2 as a direct target of miR-148a.
  • Assessment of TGFI2 expression in OC tissues and its correlation with miR-148a levels.

Main Results:

  • miR-148a was significantly downregulated in OC tissues and cell lines.
  • Overexpression of miR-148a reduced OC cell proliferation, invasion, and MMP9 levels.
  • TGFI2 was identified as a direct target of miR-148a and was upregulated in OC tissues.
  • Restoring TGFI2 expression counteracted the inhibitory effects of miR-148a.

Conclusions:

  • miR-148a inhibits ovarian cancer cell proliferation and invasion, partly by downregulating TGFI2.
  • The miR-148a/TGFI2 axis plays a significant role in the malignant progression of ovarian cancer.
  • miR-148a represents a potential therapeutic target for ovarian cancer.
