Circulating tumor cells (CTCs) are important markers for cancer diagnosis and treatment, but it is still a challenge to recognize and isolate CTCs because they are very rare in the blood. To selectively recognize CTCs and improve the capture efficiency, micro/nanostructured substrates have been
Lophophora williamsii, also known as peyote, is found primarily in dry regions from Central Mexico, including the Mexican States of Nayarit, San Luis Potosí, Zacatecas, Nuevo León, Chihuahua, Coahuila and Tamaulipas, to Texas particularly in regions along Rio Grande. Peyote extracts have been
Develop CACTUS (cancer image annotating, calibrating, testing, understanding and sharing) as a novel web application for image archiving, annotation, grading, distribution, networking and evaluation. This helps pathologists to avoid unintended mistakes leading to quality assurance, Cactus (Opuntia spp) is widely cultivated as a vegetable, fruit, and forage crop and has been used in traditional medicine in American Indian, Mexican, and Korean cultures. Accumulative evidence from both in vitro and in vivo studies using cacti suggests their biological and pharmacological
BACKGROUND
Cactus polysaccharides are the active components of Opuntia dillenii which have been used extensively in folk medicine. In this study, we investigate the anti-tumor effect of cactus polysaccharides on lung squamous carcinoma cells SK-MES-1.
METHODS
The inhibitory effect of Cactus
The ever-increasing occurrence of cancer and the severe side effects and limited efficacy of current cancer chemotherapy based on chemical drugs shift the attention toward drugs of plant origin. The Cactaceae family comprises more than 1500 species, but until recently only a few of them have been
The circulating tumor cells (CTCs) in the blood allow the noninvasive analysis of metastatic mechanisms, cancer diagnosis, prognosis, disease monitoring, and precise therapy through "liquid biopsies". However, there is no integrated and robust multifunctional microchip, which not only could highly
BACKGROUND
Cancer chemoprevention is a new approach in cancer prevention, in which chemical agents are used to prevent cancer in normal and/or high-risk populations. Although chemoprevention has shown promise in some epithelial cancers, currently available preventive agents are limited and the
We evaluated the antiproliferative effect of aqueous extracts of 14 plant foods consumed in Mexico on the breast cancer cell line MCF-7. The plant foods used were avocado, black sapote, guava, mango, prickly pear cactus stems (called nopal in Mexico, cooked and raw), papaya, pineapple, four
The protective effect of natural products such as fruits and vegetables against cancer has attracted great attention because of their fewer side effects and therefore, potentially greater safety. We have previously reported that cactus pear mixture aqueous extract (CME) reduces gynecologic cancer
IκB proteins are the primary inhibitors of NF-κB. Here, we demonstrate that sumoylated and phosphorylated IκBα accumulates in the nucleus of keratinocytes and interacts with histones H2A and H4 at the regulatory region of HOX and IRX genes. Chromatin-bound IκBα modulates Polycomb recruitment and
Artificial environmental conditions in tissue culture, such as elevated relative humidity and rich nutrient medium, can influence and modify tissue growth and induce spontaneous changes from characteristic organization pattern to unorganized callus. As succulent plants with crassulacean acid
The protective activity of prickly pear cactus (Opuntia ficus indica var. saboten) fruit juice and its main constituent, betanin, were evaluated against stress-induced acute gastric lesions in rats. After 6 h of water immersion restraint stress (WIRS), gastric mucosal lesions with bleeding were
In vitro propagated plants of the cactus Mammillaria gracillis Pfeiff. (Cactaceae) spontaneously produced callus. The habituated callus regenerated normal and hyperhydric shoots without the addition of grown regulators. Tumours were obtained by infecting cactus explants with Agrobacterium
Pestalotiopsis microspora, isolate NE-32, is an endophyte of the Himalayan yew (Taxus wallichiana) that produces taxol, an important chemotherapeutic drug used in the treatment of breast and ovarian cancers. Conditions were determined to induce the perfect stage (teleomorph) of this organism in the
