Introduction Wheat (Triticum sp.), an extensively adapted crop, is one of the primitive and primary staple food crops in the world. Wheat is cultivated from temperate; dry to irrigated or rain-fed areas, to warm, humid or cold conditions. Such a high adaptability is attributed to its intricate genome (Acevedo et al., 2002). Wheat cultivation covers more land area compared to other commercial crops and endures to be an essential food grain for humans (Curtis, 2002). Estimations reveal that by 2050, the population of the world will reach 9.1 billion (34 percent greater than today); correspondingly, the food requirement and ...

Transcriptional regulation of gene expression

Gene expression in eukaryotic cells is regulated at transcriptional, post transcriptional and translational levels (Tomizawa,  Lekstrom-Himes, and Xanthopoulos 17). Transcriptional control is the primary means of regulating gene expression. Eukaryotic transcriptional control functions at three levels: modulation of the activities of activators and repressors; variations in chromatin structure; and effect of activators and repressors on assembly of initiation complexes (Lodish et al. 368). Regulation of transcription initiation is the most widespread form of gene control in eukaryotes. However, in some cases, transcription may be attenuated and regulated at subsequent steps, such as during or after the transcription process (Cooper ...

According to Squire (2009), the altered respiratory pattern in AMPK KO neonatal mice has attracted a lot of scientific approaches to reach out to traditional answers.

Cellular respiration equation:

C6H12O6+6O2→6CO2+6H2O+38ATP. Glucose+Oxygen→Carbon dioxide+Water+38ATP.

Photosynthesis equation:

6CO2+6H2O+sunlight, nutrients→C6H12O6+6O2. Carbon dioxide+Water→Glucose+Oxygen. Respiration and photosynthesis are opposite processes. It means that products of cellular respiration are reactants of photosynthesis and vice versa: the products of photosynthesis are reactants for cellular respiration. It is known that plants are autotrophs. Thus, they have to realize cellular respiration because they need energy for their existence. Due to cellular respiration, they receive energy, which is used to make organic compounds (glucose) and oxygen during photosynthesis. From the other side, people are heterotrophs. They ...

Gene Expression and Signaling Class

Short Answer Different Phenotype in PTEN Mutations While PTEN is either mutated or lost in both spontaneous and heritable cancers, the p110 alpha is frequently mutated in major forms of cancer such as breast cancer, endometrial, colorectal, ovarian, and prostate cancers with a greater prevalence of breast cancers (Nagata et al., 2004). Besides, the monoallelic loss of PTEN mostly contributes to the growth of tumor in the context of other somatic mutations in which case the count of PTEN proteins correlates with the severity of cancer, an indication that PTEN is haploinsufficient in functionality. Additionally, while the gene encodes ...

Drawing from the seminar presentation, I have gathered that the mechanistic target of rapamycin (mTOR) signals various pathway functions and regulates critical functions in the placenta such as mitochondrial respiration and nutrient transport. Placental amino acid transporter activities are significantly decreased in intrauterine growth restriction (IUGR) with recent experimental research evidence suggesting that the changes directly contribute to restricted fetal growth (Jansson, 2016). In this case, placental nutrient sensing is seen to have a pivotal role in the modulation on resource allocation between the mother and fetus thus affecting overall fetal growth, preventing overgrowth of the fetus and ensuring ...

Mechanical ventilation (MV) causes oxidative stress that is responsible for adverse consequences on organs. In a situation of MV, the excessive pressure impairs the function of the mitochondrial respiratory chain leading to oxidative and nitrosative stress (Kavazis, 2009; Hafner et al., 2014). MV is commonly associated with hyperoxia where an excess of oxygen is provided. In such a case an oxidative stress can be induced when the oxygen pressure in the alveolar exceeds that of the normal breathing conditions because the biological system is not able to readily detoxify the environment from components such as reactive oxygen species (ROS) ( ...

Background

Early scientists and nutritionists believed that the most vital nutrient in living organisms, for building and maintaining the body was the protein. The role of proteins as enzymes came into existence several years later. This was around 1926 when experiments showed that enzymes were proteins. Insulin was the first protein to be sequenced. Hemoglobin was the first structure of proteins to be resolved. Myoglobin was then resolved later.

X-ray diffraction analysis (X-ray crystallography) led to the determination of the structure of the proteins (three-dimensional structure). The purification of proteins can be made possible from cellular compounds. Several methods have ...

Asthma is a chronic inflammatory disorder that causes shortness of breath, a feeling of tightness in the chest, and persistent cough. There are two primary types of asthma: intrinsic and extrinsic. Intrinsic asthma comes about through non-allergic means: cigarette smoke, stress, cold air, cleaning agents – basically anything that does not involve an allergen. Extrinsic asthma, on the other hand, comes about through an allergen such as dander, pollen or others. It leads to a constriction of the airway during an attack, leaving the victim out of breath, unable to take in more air, and with a tight feeling in their chest. In this ...
