Proteomics for Studying Antibiotic Action
To design more efficient treatments against bacterial infections, detailed knowledge about the bacterial response to the commonly used antibiotics is required. Proteomics is a well-suited and powerful tool to study molecular response to antimicrobial compounds. Bacterial response profiling from system-level investigations could increase our understanding of bacterial adaptation, the mechanisms behind antibiotic resistance and tolerance development.

Daisy Trees (Asteraceae) in Mexico
Mexico is floristically the fourth most species-rich country in the world, and Asteraceae is the most diverse vascular plant family in this country. The species exhibits a wide range of growth forms, but the tree-like habit, appropriately named daisy trees, is heavily underestimated, even though slightly different tree definitions are handled. Very little is known about their precise species number or conservation status in Mexico, so we update here the list of known Mexican daisy tree species, summarize their very diverse uses, present a general panorama of their present and future distribution, and discuss their conservation status.

Fucoidan
Since the early life of humankind on the Earth, nature represents the most powerful source for his major needs from food, energy, and therapeutics. Oceans cover more than 70% of Earth’s surface, and therefore, they continue to offer exceptional scaffolds improving the quality of human life. According to the National Oceanic and Atmospheric Administration (United States Department of Commerce), marine microbes represent 98% of ocean biomass. From more than 300,000 described organisms, 12,000 novel compounds have been discovered attracting great interest in the last decades. Marine macroalgae are rich sources of either sulfated or non-sulfated polysaccharides with a wide range of interesting medical applications. Fucoidan is a marine polysaccharide isolated mainly from brown macroalgae with interesting and promising pharmacological activities. Several articles discussed and proved the potential, versatile, and promising pharmacological activities of fucoidans.

Sulfolobus Solfataricus
Saccharolobus solfataricus is a species of thermophilic archaeon. It was transferred from the genus Sulfolobus to the new genus Saccharolobus with the description of Saccharolobus caldissimus in 2018. It was first isolated and discovered in the Solfatara volcano (which it was subsequently named after) in 1980 by two Germans microbiologists Karl Setter and Wolfram Zillig, in Solfatara volcano (Pisciarelli-Campania, Italy). However, these organisms are not isolated to volcanoes but are found all over the world in places such as hot springs. The species grows best in temperatures around 80° Celsius, a pH level between 2 and 4, and enough sulfur for solfataricus to metabolize in order to gain energy. These conditions qualify it as an extremophile and it is specifically known as a thermoacidophile because of its preference to high temperatures and low pH levels and it is also in aerobic and heterotropic categories for its metabolic system. It usually has a spherical cell shape and it makes frequent lobes. Being an autotroph it receives energy from growing on sulfur or even a variety of organic compounds. Currently, it is the most widely studied organism that is within the Crenarchaeota branch. Solfataricus are researched for their methods of DNA replication, cell cycle, chromosomal integration, transcription, RNA processing, and translation. All the data points to the organism having a large percent of archaeal-specific genes, which showcases the differences between the three types of microbes: archaea, bacteria, and eukarya.

MAPK Pathways in Cancer Metastasis
Metastasis is perhaps the most common reason for treatment failure in cancer patients, as well as the leading cause of cancer-related death. Mitogen-activated protein kinase (MAPK) are serine/threonine-protein kinases that can be activated by a variety of extracellular stimuli including growth factors, cytokines, insulin, environmental factors, and oxidative and genotoxic stress. It is becoming increasingly clear that MAPKs are involved in all the steps required for hyperproliferating cells to develop into metastatic tumors. However, scholars are currently lacking in vivo data to fully understand how MAPK signaling pathways can affect the progression of metastatic disease.

Silphium
The chemical composition of three Silphium species in the aspect of the possibility of their use for various purposes has been evaluated. The plant material of three Silphium species (S. perfoliatum, S. trifoliatum and S. integrifolium) was acquired from cultivation located in eastern Poland. The vegetative propagating material consisted of seeds and rhizomes. Content of protein (up to 22.9% in leaves of S. perfoliatum), amino acids (aspartic acid—up to 12.0%, glutamic acid—up to 9.5%, and leucine—up to 9.4%), fat (up to 4.2% in inflorescences of S. perfoliatum), cellulose (up to 42.9% in stems of S. trifoliatum), water-soluble sugars (up to 26.7% in rhizomes of S. perfoliatum) and mineral substances (ash up to 20.9% in stems of S. integrifolium, with significant levels of elements such as K, Ca, Mg, Fe, Mn) in the tested Silphium species can be an important criterion determining a positive evaluation of these plants as sources of alternative raw materials. The conducted research is meant to draw attention to the possibility of use of the biomass of three Silphium species as a potential source of ecological and renewable raw material for food, pharmaceuticals, feed and possibly also for energy generation purposes.

Bioferments
Bioferments are innovative ingredients extracted from natural raw materials by carrying out a fermentation process with appropriate strains of microorganisms. Mainly bioferments are made from plant-based raw materials. The spectrum of applications for bioferments is broad and includes properties such as skin whitening, antioxidant properties (blackberry, soybean, goji berry), anti-aging (red ginseng, black ginseng, Citrus unshiu peel), hydrating, and anti-allergic (aloe vera, skimmed milk).

A Bioinformatics Workflow of Metabolomics Analysis
Metabolomics is an emerging field that quantifies numerous metabolites systematically. The key purpose of metabolomics is to identify the metabolites corresponding to each biological phenotype, and then provide an analysis of the mechanisms involved. Although metabolomics is important to understand the involved biological phenomena, the approach’s ability to obtain an exhaustive description of the processes is limited. Thus, an analysis-integrated metabolomics, transcriptomics, proteomics, and other omics approach is recommended. Such integration of different omics data requires specialized statistical and bioinformatics software.
