Abstract
-
The three types of approved coronavirus disease 2019 (COVID-
19) vaccines that have been emergency-use listed (EUL) by
the World Health Organization are mRNA vaccines, adenovirus-
vectored vaccines, and inactivated vaccines. Canonical
vaccine developments usually take years or decades to be completed
to commercialization; however, the EUL vaccines being
used in the current situation comprise several COVID-
19 vaccine candidates applied in studies and clinical settings
across the world. The extraordinary circumstances of the
COVID-19 pandemic have necessitated the emergency authorization
of these EUL vaccines, which have been rapidly
developed. Although the benefits of the EUL vaccines outweigh
their adverse effects, there have been reports of rare but
fatal cases directly associated with COVID-19 vaccinations.
Thus, a reassessment of the immunological rationale underlying
EUL vaccines in relation to COVID-19 caused by SARSCOV-
2 virus infection is now required. In this review, we discuss
the manifestations of COVID-19, immunologically projected
effects of EUL vaccines, reported immune responses,
informed issues related to COVID-19 vaccination, and the
potential strategies for future vaccine use against antigenic
variants.

Abstract
-
In vitro fecal fermentation is an assay that uses fecal microbes
to ferment foods, the results of which can be used to
evaluate the potential of prebiotic candidates. To date, there
have been various protocols used for in vitro fecal fermentation-
based assessments of food substances. In this study,
we investigated how personal gut microbiota differences and
external factors affect the results of in vitro fecal fermentation
assays. We used Cheonggukjang (CGJ), a Korean traditional
fermented soybean soup that is acknowledged as
healthy functional diet. CGJ was digested in vitro using acids
and enzymes, and then fermented with human feces anaerobically.
After fecal fermentation, the microbiota was analyzed
using MiSeq, and the amount of short chain fatty acids
(SCFAs) were measured using GC-MS. Our results suggest
that CGJ was effectively metabolized by fecal bacteria to produce
SCFAs, and this process resulted in an increase in the
abundance of Coprococcus, Ruminococcus, and Bifidobacterium
and a reduction in the growth of Sutterella, an opportunistic
pathogen. The metabolic activities predicted from the
microbiota shifts indicated enhanced metabolism linked to
methionine biosynthesis and depleted chondroitin sulfate
degradation. Moreover, the amount of SCFAs and microbiota
shifts varied depending on personal microbiota differences.
Our findings also suggest that in vitro fecal fermentation of
CGJ for longer durations may partially affect certain fecal
microbes. Overall, the study discusses the usability of in vitro
gastrointestinal digestion and fecal fermentation (GIDFF)
to imitate the effects of diet-induced microbiome modulation
and its impact on the host.

Abstract
-
The DNA damage checkpoint signaling pathway is a highly
conserved surveillance mechanism that ensures genome integrity
by sequential activation of protein kinase cascades.
In mammals, the main pathway is orchestrated by two central
sensor kinases, ATM and ATR, that are activated in response
to DNA damage and DNA replication stress. Patients
lacking functional ATM or ATR suffer from ataxia-telangiectasia
(A-T) or Seckel syndrome, respectively, with pleiotropic
degenerative phenotypes. In addition to DNA strand
breaks, ATM and ATR also respond to oxidative DNA damage
and reactive oxygen species (ROS), suggesting an unconventional
function as regulators of intracellular redox status.
Here, we summarize the multiple roles of ATM and ATR, and
of their orthologs in Saccharomyces cerevisiae, Tel1 and Mec1,
in DNA damage checkpoint signaling and the oxidative stress
response, and discuss emerging ideas regarding the possible
mechanisms underlying the elaborate crosstalk between those
pathways. This review may provide new insights into the integrated
cellular strategies responsible for maintaining genome
stability in eukaryotes with a focus on the yeast model
organism.

Abstract
-
Many studies have shown that hydrogen sulfide (H2S) is both
detrimental and beneficial to animals and plants, whereas its
effect on bacteria is not fully understood. Here, we report that
H2S, released by sodium hydrosulfide (NaHS), significantly
inhibits the growth of Escherichia coli in a dose-dependent
manner. Further studies have shown that H2S treatment stimulates
the production of reactive oxygen species (ROS) and
decreases glutathione (GSH) levels in E. coli, resulting in lipid
peroxidation and DNA damage. H2S also inhibits the antioxidative
enzyme activities of superoxide dismutase (SOD),
catalase (CAT) and glutathione reductase (GR) and induces
the response of the SoxRS and OxyR regulons in E. coli. Moreover,
pretreatment with the antioxidant ascorbic acid (AsA)
could effectively prevent H2S-induced toxicity in E. coli. Taken
together, our results indicate that H2S exhibits an antibacterial
effect on E. coli through oxidative damage and suggest
a possible application for H2S in water and food processing.

Abstract
-
Organisms living in extreme environments have evolved a
wide range of survival strategies by changing biochemical and
physiological features depending on their biological niches.
Interestingly, organisms exhibiting high radiation resistance
have been discovered in the three domains of life (Bacteria,
Archaea, and Eukarya), even though a naturally radiationintensive
environment has not been found. To counteract
the deleterious effects caused by radiation exposure, radiation-
resistant organisms employ a series of defensive systems,
such as changes in intracellular cation concentration, excellent
DNA repair systems, and efficient enzymatic and non-enzymatic
antioxidant systems. Here, we overview past and recent
findings about radiation-resistance mechanisms in the
three domains of life for potential usage of such radiationresistant
microbes in the biotechnology industry.

Abstract
-
The phosphorylation of C-terminal domain (CTD) of Rpb1p, the largest subunit of RNA polymerase II plays an important role in transcription and the coupling of various cellular events to transcription. In this study, its role in DNA damage response is closely examined in Saccharomyces cerevisiae, focusing specifically on several transcription factors that mediate or respond to the phosphorylation of the CTD. CTDK-1, the pol II CTD kinase, FCP1, the CTD phosphatase, ESS1, the CTD phosphorylation dependent cis-trans isomerase, and RSP5, the phosphorylation dependent pol II ubiquitinating enzyme, were chosen for the study. We determined that the CTD phosphorylation of CTD, which occurred predominantly at serine 2 within a heptapeptide repeat, was enhanced in response to a variety of sources of DNA damage. This modification was shown to be mediated by CTDK-1. Although mutations in ESS1 or FCP1 caused cells to become quite sensitive to DNA damage, the characteristic pattern of CTD phosphorylation remained unaltered, thereby implying that ESS1 and FCP1 play roles downstream of CTD phosphorylation in response to DNA damage. Our data suggest that the location or extent of CTD phosphorylation might be altered in response to DNA damage, and that the modified CTD, ESS1, and FCP1 all contribute to cellular survival in such conditions.
