Biofizika
|January 14, 2010
Summary
Hairpin oligonucleotides (HP1) enhance the delivery of actinomycin, a heterocyclic antibiotic, into cancer cells. This suggests HP1 can act as a molecular carrier for targeted cancer therapy.
Area of Science:
- Molecular Biology
- Biochemistry
- Cancer Research
Context:
- Actinomycin is a potent antibiotic with applications in cancer treatment.
- Efficient delivery of chemotherapeutic agents into cancer cells remains a challenge.
- Hairpin oligonucleotides (HP1) are short DNA structures with potential for drug delivery.
Purpose:
- To investigate the redistribution of actinomycin from hairpin oligonucleotide HP1.
- To evaluate the efficacy of HP1-actinomycin complexes in delivering the drug into cancer cells.
- To explore the potential of HP1 as a carrier for heterocyclic antibiotics.
Summary:
- The study observed the transfer of actinomycin from HP1 to both free DNA and intracellular DNA.
- Actinomycin delivered via HP1 demonstrated more effective penetration into cancer cells compared to the free antibiotic.
- This indicates that HP1 facilitates the cellular uptake of actinomycin.
Impact:
- Hairpin oligonucleotides show promise as novel drug delivery vehicles for cancer chemotherapy.
- This approach could improve the targeted delivery of heterocyclic antibiotics, enhancing therapeutic outcomes.
- Findings may pave the way for developing new strategies in targeted cancer treatment.

Generation of Straight or Branched Actin Filaments
The straight or branched structure formation of actin filaments is controlled by nucleating proteins such as the formins and Arp2/3 complex. Formin-mediated assembly results in straight filaments, whereas Arp2/3 protein complex-mediated assembly results in branched actin filaments.
Arp2/3 Complex
Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...

Inhibitors of Bacterial Protein Synthesis
Aminoglycosides constitute a highly potent class of bactericidal antibiotics that exert their antimicrobial effects by targeting the bacterial ribosome, specifically disrupting protein synthesis. These polycationic molecules consist of amino-modified sugars linked via glycosidic bonds to an aminocyclitol core such as 2-deoxystreptamine or streptamine. Their strong positive charges facilitate tight binding to the negatively charged phosphate backbone of ribosomal RNA (rRNA), primarily at the 16S...
Actin Filament Depolymerization
Actin filaments (F-actin) are composed of actin subunits. The dissociation of actin monomers can occur from either end of F-actin. The rate of dissociation is faster from the minus-end or the pointed end, where the actin subunits exist with a bound ADP, together known as ADP-actin. The depolymerization of F-actin is aided by proteins, including the actin-depolymerizing factor (ADF) and cofilin family of proteins, gelsolin, and glia maturation factor (GMF).

Introduction to Actin
Actin is a highly conserved cytoskeletal protein found abundantly in eukaryotic cells. It constitutes 10% weight of the total cellular protein in muscle cells, while in non-muscle cells, it is lower and makes up around 1–5 percent of the total cell protein. Actin found in the unicellular amoebae and complex multicellular animals is around 80% similar, demonstrating their conservation over a billion years of evolution. Actin coding genes are conserved within species and across different species.
Formation of Higher-order Actin Filaments
The polymerization of G-actin monomers into filamentous F-actin is a multi-step process. Once the F-actins are formed, they can bundle together in different arrangements to form higher-order networks and regulate cellular functions. Common examples include the formation of lamellipodia and filopodia at the cell's leading edge by actin reorganization in a migrating cell. The microvilli on the brush border epithelial cells are also formed through the F-actin network.

Actin Polymerization
Actin polymerization occurs through the head-to-tail association of binding sites on monomeric actin or G-actin to form filamentous or F-actin. The polymerization can be divided into three phases ̶ nucleation, elongation, and steady-state phase.
The nucleation phase involves forming a stable nucleus consisting of three actin monomers to form a new actin filament. Actin-binding proteins such as formins and Arp2/3 complex help filament growth post-nucleation. The Formins form straight actin...
