Article Synopsis
  • The F-box protein Coronatine Insensitive (COI) is crucial for jasmonic acid signaling in plants, with six COI proteins identified in maize.
  • Genetic studies revealed that the coi2a coi2b double mutant produces non-viable pollen, and the coi1 quadruple mutant experiences growth and photosynthetic issues, along with alterations in hormone signaling.
  • Coexpression experiments demonstrated that COI proteins promote the degradation of DELLA proteins, affecting GA signaling, and showed that COI2a is localized in the nucleus and interacts with JAZ proteins, highlighting the diverse roles of maize COI proteins in plant growth and defense.

Virus-mediated transient gene overexpression and gene expression silencing can be used to screen gene functions in plants. Sugarcane mosaic virus (SCMV) is a positive strand RNA virus in the Potyviridae family that has been modified to be used as vector to infect monocots, including maize (), for transient gene overexpression and gene expression silencing. Relative to stable transformation, SCMV-mediated transient expression in maize has the advantages of being faster and less expensive.

Human interferon α2 (IFNα2) and thymosin α1 (Tα1) are therapeutic proteins used for the treatment of viral infections and different types of cancer. Both IFNα2 and Tα1 show a synergic effect in their activities when used in combination. Furthermore, the therapeutic fusion proteins produced through the genetic fusion of two genes can exhibit several therapeutic functions in one molecule.

The use of interferon α-2 in combination with thymosin α-1 shows higher anti-cancer effect in comparison when both are used individually because of their synergistic effects. In this study we produced an important human interferon α-2-thymosin α-1 (IFNα2-Tα1) fusion protein with probable pharmaceutical properties coupled to its high-level expression, characterization, and study of its biological activity. The IFNα2-Tα1 fusion gene was constructed by over-lap extension PCR and expressed in expression system.

Interferon therapy for the treatment of hepatitis C virus infection has very limited clinical application due to short serum half-life and side effects of therapy in systemic route of administration. In the present study, we have focused to improve the interferon therapy by overcoming the limitation of side effects. We hypothesized that latent interferon alpha 2b (IFNα2b) produced by fusion of Latency associated protein (LAP) domain of TGFβ and IFNα2b having HCV NS3 protease cleavage site as linker that will be activated only at target site (liver) by viral protease (HCV NS3 protease) present on the surface of infected cells.

The use of Moringa oleifera as natural food preservative has been evaluated in the present study. In addition, for quality assurance, the study has also been focused on the shelf life of product to authenticate the identification of plant by development of DNA based marker. Among the different extracts prepared from flower pods of Moringa oleifera, methanol and aqueous extract exhibited high antibacterial and antioxidant activity, respectively.

Background: The emerging resistance of pathogen against the currently available antimicrobial agents demands the search of new antimicrobial agents. The use of medicinal plants as natural substitute is the paramount area of research to overwhelm the drug resistance of infectious agents. Scientists have not made enough effort on the evaluation of safety of medicinal plant yet.

The uptake of iron is increased by cancer cells. Iron magnetic nanoparticles (MNP) can be used as a nanovehicle for immobilization of anticancer medicines and to integrate them at a target site. The anticancer medicines doxorubicin (DOX) and methotrexate (MTX) were immobilized separately and in combination onto MNP by a glutaraldehyde activation method and confirmed by magnetic nanoparticles linked immunosorbent assay (MagLISA) and Fourier-transform infrared (FTIR) spectroscopy.

Interferon alpha 2b (IFNα-2b) is an important cytokine and used for antiviral and anticancer treatment. The low cost production of IFNα-2b with high biological activity is necessary to provide the interferon therapy to the hepatitis patients in Pakistan. In the present study, human interferon alpha 2b (hIFNα-2b) gene from a healthy person was cloned and overexpressed in E.

Background: Salmonella Typhi is a pathogenic bacterium that causes a number of infectious diseases such as gastroenteritis and typhoid fever. In this study, an antigenic (34 kDa) protein was identified, purified, and characterized from outer membrane of Salmonella typhi.

Methods: Immunoblot analysis was used to screen antigenic proteins from outer membrane of Salmonella Typhi.

Background: Herbs and spices are very important and useful as therapeutic agent against many pathological infections. Increasing multidrug resistance of pathogens forces to find alternative compounds for treatment of infectious diseases.

Methods: In the present study the antimicrobial potency of garlic and ginger has been investigated against eight local clinical bacterial isolates.
