However, many other potentially preventive and therapeutic aspects associated with the use of components of these secretions are still partially known and have sparked some research, including in the context of cancer. A narrative mini-review to present potential beneficial effects of colostrum components for cancer patients, especially focusing on oxidative aspects and potentialities of colostrinin.

Cancer can affect almost any part of the body and has many Cancer is a generic term for a large group of anatomic and molecular subtypes that each diseases characterized by the growth of require specific management strategies. Cancer abnormal cells beyond their usual boundaries is the second leading cause of death globally and that can then invade adjoining parts of the body is estimated to account for 9.6 million deaths in _____________________________________________________________________________________________________ *Corresponding author: E-mail: [email protected]; França-Botelho; AORJ, 2(1): 1-6, 2019; Article no.AORJ.52904 2018. Lung, prostate, colorectal, stomach and mitochondria can be partially reduced by liver cancer are the most common types of generating reactive oxygen species (ROS), such cancer in men, while breast, colorectal, lung, as superoxide anion (O2-), hydrogen peroxide cervix and thyroid cancer are the most common (H2O2) and hydroxyl radical (OH-). When failure among women [1]. the balance between ROS production and elimination failure, which is called oxidative The incidence of cancer is growing globally at a stress, occurs, damage to DNA, RNA, lipids and pace that follows the aging population due to proteins can occur. In addition to DNA increased life expectancy. It is a direct result of fragmentation, the ROS can cause malfunction of the great global transformations of recent the DNA repair system, contributing to the decades, which have changed the health development of diseases, including cancer [3]. situation of peoples through accelerated urbanization, new lifestyles, new consumption The body's antioxidant defense system has the patterns [2]. primary function of inhibiting or reducing the damage to cells caused by reactive oxygen The high prevalence and mortality of cancer species. There are a wide variety of antioxidant encourages the investigation of cellular and substances, which can be classified according to molecular mechanisms that may contribute to origin and / or location into dietary antioxidants more effective preventive and therapeutic and intra and extracellular antioxidants. The means. Considering that humans are normally mechanism of action also allows them to be exposed to various cancer-inducing agents, classified as prevention antioxidants (prevent the including those obtained through diet, possible formation of free radicals), scavengers (prevent strategies involve lifestyle and diet. the attack of free radicals on cells) and repair There is a growing interest in research involving (favor the removal of DNA molecule damage and functional and nutraceutical foods that can the reconstitution of damaged cell positively impact people's health, especially in membranes [4]. the context of cancer prevention and treatment. Given this, the present mini- Superoxide dismutase (SOD) has been reported review becomes relevant because it proposes as an important antioxidant mechanism present to present potential beneficial effects of in eukaryotes and prokaryotes, strict aerobic and colostrum components for cancer patients, microaerophil organisms. This enzyme requires a especially focusing on oxidative aspects and metal as a cofactor for its functional activity, potentialities of colostrinin. which may be copper (Cu-SOD), manganese (Mn-SOD) or iron (Fe-SOD). This enzyme acts 2. RESEARCH METHODOLOGY by catalyzing the dismutation of the superoxide anion. Dismutation is a reaction in which two This is a review of narrative literature, with identical molecules are transformed into different theoretical and contextual information plus compounds. In the case of SOD, one superoxide interpretations of the researcher considering the ion oxidizes the other, generating O2 (normal) existing scientific production. and hydrogen peroxide (H2O2). Hydrogen peroxide may be further degraded by catalase or 3. OXIDATIVE METABOLISM AND peroxidase [5]. APOPTOSIS - + 2 O 2 + 2 H --------------- O 2 + H 2 O 2 When you breathe, you give all your cells the Patients with neoplasia have high concentrations oxygen they need to produce energy through a of oxidizing markers and low concentrations of process known as oxidative metabolism. In short, antioxidant substances. Regarding the severity of oxygen is reduced and glucose covalent bonds the disease, it is known that the antioxidant are broken releasing carbon dioxide, water and system behaves differently according to the energy. The main cell organelle involved is the stage of cancer. As disease progresses, lower mitochondria, where several enzymes are concentrations of enzyme antioxidant markers responsible for catalyzing the stages of this are found [6]. process. In each of these steps there is the formation of byproducts that are mostly Oberley and Buettner [7] showed differences beneficial. However, approximately 5% may be between superoxide dismutase activity of cancer toxic to the cell at high concentrations. Oxygen, cells. Decreased amounts were found in many for example, during electron transport in tumors and they produced more superoxide. 2 França-Botelho; AORJ, 2(1): 1-6, 2019; Article no.AORJ.52904 Tumors possess and acquire characteristics and endoplasmic reticulum and nuclear membrane abilities to maintain their survival and [14]. development. These include the ability to maintain proliferative signaling, evade growth In the context of cancer, pro-apoptotic limbs are suppressive mechanisms, resist cell death, characterized as apoptotic performers, acting as perpetuate its replicative capacity, induce tumor suppressors while pro-survival limbs are angiogenesis, and activate invasion and regarded as apoptosis inhibitors, acting as metastasis. Underlying these characteristics are oncoproteins [15]. genomic instability, inflammation, imbalance of cellular energy metabolism, and the ability to Apoptosis in clinical practice is a target for evade immune destruction, which have been the potential therapeutic use of programmed cell subject of countless studies in the last decade death or for understanding the mechanisms of [8]. resistance to radiotherapy and chemotherapy. Many alternatives seeking cancer treatment are Tumor growth is related to a balance resulting based on the induction of tumor cell apoptosis from the sum between proliferation and cell [16]. The elucidation of some of the molecular death. Combined measurement of cell death and mechanisms of apoptosis can generate proliferation is an important weapon in the most perspectives of modulation of these processes realistic prediction of tumor behavior. The [17]. genetically controlled mechanism of cell death is 4. COLOSTRUM AND COLOSTRININ called apoptosis, which is critical for the elimination of damaged cells. Studies have Colostrum is defined as the first products of milk shown the relevance of programmed cell death in secretion, the result of the influence of lactogenic tissue homeostasis, organogenesis and tumor hormones, such as prolactin. It begins production pathogenesis [9,10]. at the end of pregnancy and continues until about 5 to 7 days after delivery. It is a Apoptosis is a fairly rapid cell death: cell secretion that has ten times more carotene than retraction occurs which causes loss of adherence mature milk, which gives it yellowish color [18]. with extracellular matrix and neighboring cells. Cell organelles maintain their morphology, Compared to milk, it has higher viscosity and is except in some cases for mitochondria, which made up of blood serum components such as may rupture the outer membrane. The chromatin immunoglobulins and other serum proteins such is condensed and concentrated near the nuclear as albumin, α-lactalbumin, β-lactoglobulin. In membrane, which remains intact. Next, the addition to containing many essential nutrients, in membrane cell shaped extensions (" blebs ") and concentrations higher than those commonly the core to disintegrate into fragments
