          Abstract

          Resumen Las especies reactivas de oxígeno, que inducen estrés oxidativo en el organismo, son uno de los factores de riesgo para padecer de algún tipo de cáncer. En México los tipos de cáncer con mayor mortalidad son el de próstata, mama, cervicouterino, pulmón e hígado. Los productos naturales representan la forma más antigua de remedios medicinales, para el cáncer esta fuente no es una excepción. En esta investigación, se estudió la actividad antioxidante por ABTS y DPPH, y la actividad antiproliferativa de seis plantas medicinales del noroeste de México. Las cáscaras del fruto de Jacquinia macrocarpa ssp pungens mostraron la mejor actividad antiproliferativa del estudio con una IC50 de 9.2 μg/ mL en A549, seguido por Bursera microphylla con IC50 de 13.8 μg/mL en HeLa. Bursera laxiflora obtuvo la mejor actividad antioxidante de las seis plantas frente a los radicales ABTS y DPPH, así como también presentó actividad antiproliferativa en HeLa. La corteza de B. laxiflora contiene compuestos con actividad antioxidante, que probablemente, también sean los mismos que inducen la actividad antiproliferativa en células cancerosas. Por otro lado, J. macrocarpa y B. microphylla no presentan actividad antioxidante, sin embargo, las tres especies vegetales representan una fuente potencial de moléculas con actividad antiproliferativa.

          Abstract Reactive oxygen species, which induce oxidative stress in the body, are one of the risk factors for some cancer types. In Mexico, the types of cancer with the highest mortality are prostate, breast, cervical, lung, and liver. Natural products represent the oldest form of medicinal remedies; for cancer, this source is no exception. In this investigation, we studied the antiproliferative activities, by MTT, and the antioxidant activity, by ABTS and DPPH, in six northwestern Mexico medicinal plants. The Jacquinia macrocarpa ssp. pungens fruit shells showed the best antiproliferative activity with an IC50 of 9.2 µg/mL in A549, followed by Bursera microphylla with IC50 13.8 µg/mL in HeLa. Bursera laxiflora showed the best antioxidant activity of the six plants against ABTS and DPPH radicals, and also presented antiproliferative activity in HeLa. The bark of B. laxiflora contains compounds with antioxidant activities, which are probably also the same that induce antiproliferative activity in cancer cell lines. On the other hand, J. macrocarpa showed no antioxidant activity. However, the three species of plants represent a potential source of molecules with antiproliferative activity.

          Global Cancer Statistics 2018: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries

          This article provides a status report on the global burden of cancer worldwide using the GLOBOCAN 2018 estimates of cancer incidence and mortality produced by the International Agency for Research on Cancer, with a focus on geographic variability across 20 world regions. There will be an estimated 18.1 million new cancer cases (17.0 million excluding nonmelanoma skin cancer) and 9.6 million cancer deaths (9.5 million excluding nonmelanoma skin cancer) in 2018. In both sexes combined, lung cancer is the most commonly diagnosed cancer (11.6% of the total cases) and the leading cause of cancer death (18.4% of the total cancer deaths), closely followed by female breast cancer (11.6%), prostate cancer (7.1%), and colorectal cancer (6.1%) for incidence and colorectal cancer (9.2%), stomach cancer (8.2%), and liver cancer (8.2%) for mortality. Lung cancer is the most frequent cancer and the leading cause of cancer death among males, followed by prostate and colorectal cancer (for incidence) and liver and stomach cancer (for mortality). Among females, breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death, followed by colorectal and lung cancer (for incidence), and vice versa (for mortality); cervical cancer ranks fourth for both incidence and mortality. The most frequently diagnosed cancer and the leading cause of cancer death, however, substantially vary across countries and within each country depending on the degree of economic development and associated social and life style factors. It is noteworthy that high-quality cancer registry data, the basis for planning and implementing evidence-based cancer control programs, are not available in most low- and middle-income countries. The Global Initiative for Cancer Registry Development is an international partnership that supports better estimation, as well as the collection and use of local data, to prioritize and evaluate national cancer control efforts.

              Determination of antiradical and antioxidant activity: basic principles and new insights.

              Although the term 'antioxidant' is used very frequently, there are problems with the definition of antioxidants and estimation of antioxidant activity. The distinction between antioxidant and antiradical activities is not always obvious. This minireview discusses critically the principles, advantages and limitations of the most frequently used methods of estimation of antiradical and antioxidant activities.
