Pigment Epithelium-Derived Factor In addition to TGF-β, there are many other substances in vitreous that have anti-angiogenic activity. PEDF is a 49.5-kDa monomeric protein, which is a member of theserine protease inhibitor(serpin) family. This was first purified from the conditioned medium of...
4. DISCUSSION Both the ommochrome and the pterin are deposited in granules as chromophores derived from the brown (3-hydroxykynurenine) and red (pteridine) chromogens respectively, and are assumed to be bound to proteins or polypeptides. The function of the locus of brown has been assumed to...
Directed evolution can mimic Darwinian evolution to achieve functional changes by altering the enzyme structure, and the process typically comprises library construction and artificial selection (Fig.4II). Random mutations can be introduced into the protein via either error-prone PCR or DNA shuffling. ...
Pigment epithelium-derived factor (PEDF) is a potent endogenous inhibitor of angiogenesis and a promising anticancer agent. We have previously shown that PEDF can be phosphorylated and that distinct phosphorylations differentially regulate its physiological functions. We also demonstrated that triple ...
(Fig.2). The most common strategies can be summarized as: (1) gene deletion and complementation (Bitok et al.2017); (2) amplification of target gene based on conserved sequences of known enzymes from other organisms and other methods derived thereof (Jones et al.2008); (3) sequencing ...

Adult teleost fish retinas can regenerate neurons following either surgical or pharmacological injury. The cellular milieu of the damaged retina within which regenerated neurons are produced might be different in these two model systems of retinal injury, and thus the phenotypic attributes of regenerated...
The following deductions can be derived from the above notation: The whiteness, w = 100 – (20 + 60) = 20. Redness, r = c × %R = (60 × 80)/100 = 48 Yellowness, y = c × %Y = (60 × 20)/100 = 12 or as c = r + y, y = 60 – 48 = 12. The saturation, m is...
The structures under consideration are derived from a chlorin ring, wherein a central magnesium ion is present. The side chains of the structure can vary depending on the type of chlorophyll (Strain,1944). Chlorophyll a Chlorophyll a is the most prevalent and all-encompassing kind of chlorophyll...
