Alpha-momorcharin (alpha-MMC) is a ribosome-inactivating protein (RIP) with excellent cytotoxicity to tumor cells. However, its strong immunogenicity and short plasma half-life limit its clinical applications. To overcome this, we have to PEGylated alpha-MMC using a branched 20 kDa (mPEG)
Alpha-momorcharin (α-MMC), a ribosome inactivating protein (RIP) extracted from the seeds of Momordica charantia, exerts anti-tumor, antiviral, and anti-fungal activities. However, α-MMC has an obvious toxicity that limits its clinical application. We examined the effect of α-MMC on the inhibition
Trichosanthin and alpha-momorcharin are abortifacient proteins extracted from Chinese medicinal herbs. Study of their in vitro cytotoxicities showed that the two proteins selectively injured choriocarcinoma and melanoma cells. Hepatoma cells represented the most resistant cell line among the various
1. alpha-Momorcharin, a glycoprotein isolated from seeds of the bitter gourd, Momordica charantia inhibited incorporation of [3H]thymidine, [3H]leucine and [3H]uridine into P388 (mouse monocyte-macrophage), J774 (Balb/c macrophage), JAR (human placental choriocarcinoma) and sarcoma S180 cell lines.
Ribosome-inactivating proteins (RIPs) function to inhibit protein synthesis through the removal of specific adenine residues from eukaryotic ribosomal RNA and rending the 60S subunit unable to bind elongation factor 2. They have received much attention in biological and biomedical research due to
Alpha-momorcharin (α-MMC) is a type-I ribosome inactivating protein (RIP) with a molecular weight of 29 kDa found in plants. This protein has been shown to be effective against a broad range of human viruses and also has anti-tumor activities. However, the mechanism by which α-MMC induces plant
All primary nasopharyngeal carcinoma (NPC) tumors contain hypoxic regions which are implicated in decreased local control and increased distant metastases, as well as resistance to chemotherapy in advanced NPC patients. One of the promising therapeutic approaches for NPC is to use drugs that can
Nature is a rich source of medicinal plants and their products that are useful for treatment of various diseases and disorders. Momordica charantia, commonly known as bitter melon or bitter gourd, is one of such plants known for its biological activities used in traditional system of medicines. This
Momordica charantia L., a genus of Momordica Linn. of the family Cucurbitaceae, commonly known as bitter melon, has been widely planted in China, Southeast Asia, Turkey and other areas, and has been used as a medicine for a long time. Alpha-momorcharin (α-MMC) extracted and purified from bitter
α-Momorcharin (α-MMC), a type I ribosome-inactivating protein (RIP), has shown therapeutic potential such as anti-tumor and anti-viral agent. Traditional process of α-MMC purification from bitter melon seeds was time consuming and low efficient. To take this challenge, we made an affinity matrix by
Background and aim: Alpha-momorcharin (α-MMC) is a type I ribosome-inactivating protein (RIP) that is purified from Momordica charantia. Despite its strong antitumor activities, α-MMC exerts the undesirable immunotoxicity effects of hypersensitivity or immunosuppression. Since α-MMC is
Alpha-Momorcharin (α-MMC) is a ribosome inactivating protein from Momordica charantia with anti-tumor activity. Previously, we had observed that modification of α-MMC with polyethylene glycol (PEG) could reduce toxicity, but it also reduces its anti-tumor activity in vitro. This study aims to
Alpha-momorcharin (α-MMC) is a type-I ribosome inactivating protein with a molecular weight of 29 kDa that is found in Momordica charantia, and has been shown to be effective against a broad range of human viruses as well as having anti-tumor activities. However, the role of endogenous α-MMC under
Alpha-momorcharin (α-MMC), a type I ribosome-inactivating protein, has attracted a great deal of attention because of its antitumor activity. However, the cytotoxicity of α-MMC is limited due to insufficient cellular internalization in cancer cells. To enhance the cytotoxicity of α-MMC, a
Alpha-momorcharin (α-MC), a type I ribosome-inactivating protein (RIP) isolated from Momordica charantia seeds, has been extensively studied for its antitumor, antiviral and antifungal activities. However, as an exogenous protein, problems associated with short half-life and strong immunogenicity
