Proofreading

7.5K
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

7.7K
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

5.7K
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.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair

Repressible Operon: trp Operon01:21

Repressible Operon: trp Operon

557
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...

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Glioma is a highly lethal malignant brain tumor.
  • Long noncoding RNAs (lncRNAs) are implicated in glioma development.
  • The specific role of lncRNA Urothelial Carcinoma-Associated 1 (UCA1) in glioma remains unclear.

Purpose of the Study:

  • To investigate the function of UCA1 in glioma genesis.
  • To explore UCA1 as a potential therapeutic target for glioma.

Main Methods:

  • Quantitative analysis of UCA1 expression in glioma tissues.
  • In vitro knockdown of UCA1 using si-UCA1 in U87 and U251 glioma cell lines.
  • Bioinformatics analysis and luciferase reporter assays to confirm UCA1-miR-122 interaction.
  • Assessment of cell proliferation, migration, and invasion assays.

Main Results:

  • UCA1 expression was significantly upregulated in glioma tissues, correlating with poor prognosis.
  • UCA1 knockdown suppressed glioma cell proliferation, migration, and invasion.
  • UCA1 directly binds to miR-122, acting as an endogenous sponge.
  • UCA1 promotes glioma progression by downregulating miR-122.

Conclusions:

  • lncRNA UCA1 promotes glioma cell proliferation, migration, and invasion by sponging miR-122.
  • UCA1 represents a novel therapeutic target for glioma treatment.
