E2F-RB-p53 Pathway in Tumor Suppression
The transcription factor E2F links the RB pathway to the p53 pathway upon loss of function of pRB, thereby playing a pivotal role in the suppression of tumorigenesis. E2F fulfills a major role in cell proliferation by controlling a variety of growth-associated genes. The activity of E2F is controlled by the tumor suppressor pRB, which binds to E2F and actively suppresses target gene expression, thereby restraining cell proliferation. Signaling pathways originating from growth stimulative and growth suppressive signals converge on pRB (the RB pathway) to regulate E2F activity. In most cancers, the function of pRB is compromised by oncogenic mutations, and E2F activity is enhanced, thereby facilitating cell proliferation to promote tumorigenesis. Upon such events, E2F activates the Arf tumor suppressor gene, leading to activation of the tumor suppressor p53 to protect cells from tumorigenesis. ARF inactivates MDM2, which facilitates degradation of p53 through proteasome by ubiquitination (the p53 pathway). P53 suppresses tumorigenesis by inducing cellular senescence or apoptosis. Hence, in almost all cancers, the p53 pathway is also disabled.

The Interactions between Microorganisms and Arsenic
While arsenic is a natural and inevitable part of the biogeochemical cycle, the rise in anthropogenic activities has led to its continued increase in arsenic concentrations in various environmental matrices. High arsenic concentration is considered a threat due to its recalcitrant nature as well as its capacity for highly toxic effects in plants, animals, and humans. Among all domains of life, microorganisms have been dealing with arsenic since life arose and are the most resilient to its lethal effects. Strides in elucidating the biochemical pathways of their ability to detoxify arsenic has allowed us to utilize their potential in bioremediation processes.

Biosensors for the Detection of L-Amino Acids
The field of biosensors is filled with reports and designs of various sensors, with the vast majority focusing on glucose sensing. However, in addition to glucose, there are many other important analytes that are worth investigating as well. In particular, L-amino acids appear as important diagnostic markers for a number of conditions. The need to determine L-amino acids from clinical samples has risen. More clinical data appear to demonstrate that abnormal concentrations of L-amino acids are related to various clinical conditions such as inherited metabolic disorders, dyslipidemia, type 2 diabetes, muscle damage, etc.

Nutritional Strategies to Mitigate Post-Weaning Challenges in Pigs
The pig-farming industry faces significant challenges in ensuring the health and growth of piglets, particularly during the weaning phase. This critical period involves multiple stressors, such as environmental changes, dietary shifts, and social separation, which can adversely affect the piglet’s digestive health, immune system, and overall well-being.

Fundamentals of Covalent Organic Frameworks Based Electrochemical Sensors
The international community has been paying close attention to the issue of food safety as a matter of public health. The presence of a wide range of contaminants in food poses a significant threat to human health, making it vital to develop detection methods for monitoring these chemical contaminants. Electrochemical sensors using emerging materials have been widely employed to detect food-derived contaminants. Covalent organic frameworks (COFs) have the potential for extensive applications due to their unique structure, high surface area, and tunable pore sizes.

Tryptophan and Proline Oxidation Products in Adipokinetic Hormones
Adipokinetic hormones (AKHs) regulate important physiological processes in insects. AKHs are short peptides with blocked termini and Trp in position 8. Often, proline occupies position 6. Few post-translational modifications have been found, including hydroxyproline ([Hyp6]) and kynurenine (Kyn). Researchers' latest data suggest that the Hyp- and Kyn-containing AKHs occur more often than originally thought and researchers investigated if they are natural or artifactual. Experimental evidence indicated that Hyp occurs endogenously in insect corpora cardiaca.

Kaempferol- and Quercetin-Rich Herbs in Alzheimer’s Disease Treatment
Alzheimer’s Disease (AD) is a progressive neurodegenerative disorder impairing cognition and memory in the elderly. This disorder has a complex etiology, including senile plaque and neurofibrillary tangle formation, neuroinflammation, oxidative stress, and damaged neuroplasticity. The treatment options are limited, so alternative treatments such as herbal medicine could suppress symptoms while slowing cognitive decline.
