Natural compounds as a potential modifier of stem cells renewal: Comparative analysis.

Cancer stem cells (CSCs) are indispensable for development, progression, drug resistance, and tumor metastasis. Current cancer-directed interventions target targeting rapidly dividing cancer cells and slow dividing CSCs, which are the root cause of cancer origin and recurrence. The most promising targets include several self-renewal pathways involved in the maintenance and renewal of CSCs, such as the Wnt/β-Catenin, Sonic Hedgehog, Notch, Hippo, Autophagy, and Ferroptosis.

Curcumin Oxidation Is Required for Inhibition of Growth, Translocation and Phosphorylation of Cag A.

Curcumin is a potential natural remedy for preventing -associated gastric inflammation and cancer. Here, we analyzed the effect of a phospholipid formulation of curcumin on growth, translocation and phosphorylation of the virulence factor CagA and host protein kinase Src and in an mouse model of infection. Growth of was inhibited dose-dependently by curcumin .

Interaction of turmeric ( L.) with beneficial microbes: a review.

L., commonly known as turmeric, is a rhizomatous herb of the family Zingiberaceae. It is mostly used as a spice, a coloring agent and broadly used in traditional medicine such as Ayurveda, Unani, etc.

LAT1 targeted delivery of methionine based imaging probe derived from M(III) metal ions for early diagnosis of proliferating tumours using molecular imaging modalities.

We investigated the potential of DTPA-bis(Methionine), a target specific amino acid based probe for detection of L-type amino acid transporters (LAT1) known to over express in proliferating tumours using multimodality imaging. The ligand, DTPA-bis(Met) was readily converted to lanthanide complexes and was found capable of targeting cancer cells using multimodality imaging. DTPA-bis(Met) complexes were synthesized and characterized by mass spectroscopy.

Melatonin protects against clomiphene citrate-induced generation of hydrogen peroxide and morphological apoptotic changes in rat eggs.

The present study was aimed to determine whether clomiphene citrate-induces generation of hydrogen peroxide in ovary, if so, whether melatonin could scavenge hydrogen peroxide and protect against clomiphene citrate-induced morphological apoptotic changes in rat eggs. For this purpose, forty five sexually immature female rats were given single intramuscular injection of 10 IU pregnant mare's serum gonadotropin for 48 h followed by single injections of 10 IU human chorionic gonadotropin and clomiphene citrate (10 mg/kg bw) with or without melatonin (20 mg/kg bw) for 16 h. The histology of ovary, ovulation rate, hydrogen peroxide concentration and catalase activity in ovary and morphological changes in ovulated eggs were analyzed.

Verapamil reversibly inhibits spontaneous parthenogenetic activation in aged rat eggs cultured in vitro.

The present study was designed to investigate whether verapamil could inhibit spontaneous parthenogenetic activation in aged rat eggs cultured in vitro. Eggs collected from oviduct after 19 h post human chorionic gonadotropin (hCG) were arrested at the metaphase-II (M-II) stage and exhibited a first polar body. Culture of these aged eggs in calcium/magnesium (Ca(2+)/Mg(2+))-deficient and serum-free medium for 3 h induced exit from M-II, a morphological sign of spontaneous parthenogenetic activation in all eggs.
