Climate change poses a substantial threat to global crop yield. Moreover, crop production is likely to reduce in the near future because of increasing average temperatures, widespread extreme climate events, and the loss of agricultural land. Abiotic stresses are the major factors limiting the growth and development of various crops worldwide. They cause the buildup of reactive oxygen species (ROS), which leads to cellular damage in a variety of subcellular compartments in plants. The metabolic rate of ROS is criti [...]

The autophagy mechanism recycles the damaged and long-standing macromolecular substrates and thus maintains cellular homeostatic and proteostatic conditions. Autophagy can be an unavoidable target in cancer therapy because its deregulation leads to cancer formation and progression. Cancer can be controlled by regulating autophagy at different genetic, epigenetic, and post-translational levels. Epigenetics refers to the heritable phenotypic changes that affect gene activity without changing the sequence. Modern biol [...]

Recent findings indicate that the microbiota is involved in the development of lung cancer by inducing inflammatory responses and generating genome damage. This study aimed to compare sputum microbiomes from the mouth and oropharynx in non-small cell lung carcinoma (NSCLC) patients. A second goal was to search for bacterial taxonomic units that behave differently in the microbiome of NSCLC patients and healthy subjects. In the study, the taxonomic composition of the sputum and oropharyngeal microbiomes of 23 male p [...]

Double aneuploidy is the co-occurrence of aneuploidy of two different chromosomes within the same individual. Genomic imbalance associated with two aneuploidies in humans is associated with early lethality, and observation in live-born humans is rare. In isolation, trisomy of chromosomes 13, 18, 21, X, and Y may be better tolerated, whereas monosomy of X is the only such type of aberration that may be compatible with life. It is hypothesized that two successive malsegregation events must occur in early development [...]

People choose how and if to generate and disclose not just personal genomic data, but also multiple other types of personal health and non-health related data. To contextualize choices about genetic testing and genetic data disclosure, we explored perspectives of genomic data privacy and disclosure compared to other types of data. We conducted a qualitative focus group study with adult members of an integrated U.S. health system, using administrative data to stratify our sample by age and by race/ethnicity. Discuss [...]

The efficient production of transgenic (Tg) piglets has remained a challenge in the field of domestic animal studies. Unlike mice, the pronuclei of pig zygotes cannot be easily studied because of the abundance of lipid droplets. Therefore, the zygotes must be briefly centrifuged before pronuclear injection (PNI) to move the lipid droplets to the periphery of the zygote for PNI-mediated production of Tg piglets. However, this procedure is temporal because lipid droplets return to the original space during PNI, hampe [...]

Gaucher disease (GD) is one of the most common lysosomal storage disorders resulting from biallelic mutations in the GBA1 gene, causing a dysfunction of the lysosomal hydrolase, glucocerebrosidase (acid-β-glucosidase; E.C 3.2.1.45). Clinical manifestations are heterogenous and can include splenomegaly, anemia, and neurological impairments in the case of neuronopathic Gaucher disease types 2 and 3. Newborn screening, arguably the most important public health initiative to date, has been regularly conducted on newbor [...]

This paper suggests an approach for the use of a single paucicellular histological sample to investigate two characteristics indicative of the cell’s functional potential: 1) the content of telomerase reverse transcriptase (TERT) and 2) the telomere length. An algorithm has been suggested for the successive detection of the catalytic telomerase subunit with immunohistochemical staining and assessment of telomere length with Q-FISH on the same set of cells. The described approach uses three incontestable advantages [...]

High-altitude pulmonary edema (HAPE) and COVID-19 pneumonia are different diseases, but HAPE-susceptible individuals (whose susceptibility often has a genetic basis) can also suffer from severe COVID-19. We hypothesized that certain pathogenic mechanisms might overlap if such a coincidence occurs, since these patients could react to alveolar hypoxia with a more intense and heterogeneously distributed pulmonary vasoconstriction than non-HAPE-susceptible patients. It is also not known how future altitude acclimatizat [...]

Mosaicism for trisomy of chromosome 14 (T14) is a very rare chromosomal disease in liveborn patients. Since the 1970s, when the first patients with mosaicism for T14 were reported, a number of studies on the clinical manifestations of this abnormality have been published. No information on epidemiological parameters was known except for the rarity of the disease and its predominance among female carriers. This was the first systematic review of published cases of mosaic T14 that addressed some epidemiological aspec [...]
