As we know, in general, reactive Oxygen species (ROS) are essential for the normal biological functions of cells but on other hand, they are also involved in cellular degeneration and tissue death. So, there is a basic need for such chemical or compound which is antioxidant in nature and very specific in its functions to combat the production of ROS (which induces cellular death) without altering the production of normal ROS that are required for cellular functions. That’s why Ferostatin-1 is developed. It is a very potent chemical agent for inhibiting ferroptosis which is defined as an oxidative, somewhat regulated, and nonapoptotic death of a cell.

n6-methyladenosine (m6A) is an internal RNA-modifying enzyme primarily catalyzed by the METTL3-METTL14 methyltransferase complex. The m6A methyltransferase METTL3 has been implicated in the initiation and maintenance of acute myeloid leukemia (AML), but the potential application of targeting this enzyme remains unclear. Here, we present the identification and characterization of STM2457 and the crystal structure of STM2457 in complex with METTL3-METTL14. STM2457 is a potent and selective METTL3 catalytic inhibitor, and tumor treatment with STM2457 resulted in decreased AML growth and increased differentiation and apoptosis. Concomitant with selective reduction of m6A levels of leukemic mRNAs, expression consistent with translational defects was reduced. The investigators demonstrated that METTL3 inhibition in vivo resulted in impaired engraftment and prolonged survival in various mouse models of AMTL, particularly targeting key stem cell subsets of AML. Collectively, these results reveal METTL3 inhibition as a potential therapeutic strategy against AML, and targeting of RNA-modifying enzymes is a promising anticancer therapeutic avenue.

When people are hungry, the stomach produces Ghrelin, which makes people feel hungry and promotes appetite, and after eating, fat cells produce Leptin, which makes people feel full and suppresses appetite. This homeostasis between ghrelin and leptin has long been thought to be critical for metabolism and diet.

The Human Genome Project (HGP) has successfully mapped the human genome, and human beings have also obtained their own "natural book". However, in the following 20 years, the interpretation of this "book from the sky" has been very difficult, and until now, we still lack sufficient understanding of the expression patterns of the human genome.

Trigeminal neuralgia is the most common cranial nerve disease, characterized by recurrent paroxysmal severe pain in the distribution area of the trigeminal nerve on one side of the face. The patient's daily activities, such as eating, drinking, talking, washing face, brushing teeth, etc., can cause severe pain, and some patients can even cause excruciating pain when the breeze blows. Therefore, trigeminal neuralgia is also known as "the first pain in the world", and some patients even choose to commit suicide to end the pain. Those who endure pain also tend to have lower quality of life, anxiety and depression.

Nature has long used large biomolecular assemblies to convert chemical energy into quasi-mechanical motion to perform essential functions of life. For example, cells use translation machinery -- the ribosome -- to make proteins from mRNA templates. Cellular nanomachines regulate the extent of translation by using miRNAs to guide AGO protein assembly into RISC to the 3' untranslated region. Similar to other machines, the ribonucleoprotein complex (RNP) requires the correct assembly of the correct number and type of molecules to perform its function. Any single misfolding or genetic mutation can lead to loss of function or abnormality and lead to disease. Intracellular single-molecule fluorescence microscopy (SMFM) imaging can be used to probe the structure and activity of individual machine components in their cellular environment. But the lack of high-yield methods to fluorescently label RNA molecules has hindered the development of SMFM.

The first two centuries were marked by the elucidation of the structure and function of nucleic acids. Friedrich Michel was the first to isolate nuclear proteins in 1869. The name nucleic acid is a coined term that Albrecht Kossel divided into five bases in the late 19th century: adenine, cytosine, guanine, thymine and uracil. Another half century later, Ossivard Avery discovered that deoxyribonucleic acid (DNA) was involved in heredity, laying the foundation for molecular biology genetics. In addition, Chargaff's biochemical discovery of fixed ratios of certain bases, as well as Franklin's crystallographic studies, led Watson and Crick to discover the structure and function of DNA in 1953. However, the role of RNA and its connection to DNA and proteins remain unclear.

Lung cancer is one of the cancers with the highest mortality rate in the world, and non-small cell lung cancer (NSCLC), as its main type, threatens people's health and longevity. Medical experts have carried out a lot of basic research on lung cancer, and have also developed many targeted drugs, but the changes in the disease are always one step ahead, and more new drugs and treatment strategies are urgently needed to deal with it.

Since its discovery in 1979, the p53 gene has been one of the focuses of oncology research. Searching the Pubmed database with p53 as the keyword can find more than 100,000 articles. In a 2017 statistic by Nature magazine, the p53 gene ranked first in the list of the most popular research genes in the past few decades by an absolute advantage.

Alzheimer's disease (AD), commonly known as Alzheimer's disease, is a progressive neurodegenerative disease with an insidious onset. Generally, the onset before the age of 65 is called Alzheimer's disease; the onset after the age of 65 is called senile dementia. The pathogenesis of AD is complex, and related studies suggest that neuritic plaques composed of extracellular β-amyloid and many other proteins are one of the main lesions, and even begin to deposit twenty years before the onset of AD patients. Scientists have developed some drugs around the mechanism of inhibiting the deposition of beta-amyloid plaques, but these can only slow the progression of the disease and cannot effectively reverse or improve the disease. Although a lot of research and achievements have been made, in fact, the root cause of AD pathogenesis is not yet clear and there is no direct and effective treatment.
