Ovarian cancer has the highest mortality rate among gynecological cancers; the most effective therapy for this cancer is a combination of radiation treatment and chemotherapy. However, radiation resistance is the leading factor associated with treatment failure. The present study aimed to investigate pseudolaric acid B (PAB) as a potential radiosensitizer for the treatment of ovarian cancer. Th...

OBJECTIVE To assess the effects of Jinlongshe Granules (JLSG) on tumor growth of gastric carcinoma. METHODS Fifty nude mice orthotopically transplanted with MKN-45 human gastric cancer cells were divided into five groups: untreated group, 5-fluorouracil (5-FU)-treated group and high-, medium-, and low-dose JLSG-treated groups. Corresponding antitumor drugs were administered in each group exce...

B-cell receptor-associated protein 31 (BAP31) is an endoplasmic reticulum (ER) membrane protein which plays a role as a molecular chaperone for the newly synthesized transmembrane proteins. BAP31 is also an important apoptosis regulator for extrinsic apoptosis induction in the ER membrane. Recent studies have shown that BAP31 is also expressed on the surface of embryonic stem cells. However, th...

Integrity of the sperm membrane, of which phosphatidyl serine (PS) plays a central role, is essential for fertilization. The externalisation of PS (EPS) occurs during capacitation and the acrosome reaction. EPS, from the inner to the outer membrane, is considered as a sign of early apoptosis. Therefore, EPS may have a dual function in sperm. This study has evaluated the relationship between EPS...

A series of novel peptidomimetics bearing dehydroepiandrosterone moiety were designed, synthesized, and evaluated for their inhibition activities against cell proliferation. According to the preliminary studies on inhibitory activities, some of the newly prepared compounds indicated significantly inhibition activities against human hepatoma cancer (HepG2), human lung cancer (A549), human melano...

A novel series of hybrids (7a-l, 8a-l) from β-carboline and salicylic acid (SA) were designed and synthesized, and their in vitro biological activities were evaluated. Most of the hybrids displayed potent antiproliferative activity against five cancer cell lines in vitro, showing potencies superior to 5-FU and harmine. In particular, compound 8h selectively inhibited proliferation of liver canc...

To evaluate the in vitro anticancer activity and to investigate the mechanism of action of a thiophene heterocyclic compound, [3-Amino-5-[(2,6-dimethylphenyl)amino]-4-(phenylsulfonyl)-2-thienyl](4-fluorophenyl)methanone (APTM) against human colon cancer HCT116 cells. Sulforhodamine B assay and colony formation assay for cell proliferation assay; propidium iodide (PI) staining for cell cycle pro...

BACKGROUND LA-12 is a new platinum (IV) drug with promising cytotoxic effects in a wide range of cancer cell lines. Its confluence-dependent effects were compared with cisplatin (CDDP) and oxaliplatin (L-OHP) in HT-29 cells. MATERIALS AND METHODS Cytotoxicity was determined by MTT test, eosin exclusion assay, and cell number quantification. The cell cycle was analysed using propidium iodide D...

Cyclosporine A (CsA) is neuroprotective in ischemic brain injuries of adult animals because it blocks the permeability transition of the mitochondrial membrane. In this study, we examined the neuroprotective effect of CsA on hypoxia-ischemia (HI)-induced brain injury in newborn rats. Seven-day-old Sprague-Dawley rat pups were subjected to 2h of 8% oxygen following a unilateral carotid artery li...

In the course of searching for novel cytotoxic compounds which can be used in chemotherapy, several Traditional Chinese Medicines (TCM) have been screened by bioassay-guided fractionation and isolation. An extract of rhizomes of Iris tectorum Maxim., a TCM used to treat cancer, exhibited highest potency and led to the isolation of two flavonoids, 7-O-methylaromadendrin and tectorigenin, and fou...
