Development And Evolution

Coronaviruses are a group of RNA viruses, which cause diseases in humans. The emergence of COVID-19, has caused a global pandemic. It is focused on developing an effective therapeutic strategy against COVID-19. To better understand the development and evolution of therapeutic strategies against coronaviruses, we conducted US granted patents analysis. The results showed vaccines played a leading role in therapies against coronaviruses. Both attenuated vaccines and recombinant genetic vaccines were very important approaches in vaccine development against coronaviruses. It is not a rapid approach to develop peptide drugs against COVID-19 or future novel coronaviruses. The study was the first one to show the development and evolution in therapeutic strategies against coronaviruses based on patent insight. The present study provides a new insight into the development of therapeutic strategies against coronaviruses.

Effective Therapeutic Strategy

In 2019 an outbreak occurred which resulted in a global pandemic. The causative agent has been identified in a virus belonging to the Coronaviridae family, similar to the agent of SARS, referred to as SARS-CoV-2. This epidemic spread rapidly globally with high morbidity and mortality. Although vaccine development is at a very advanced stage, there are currently no truly effective antiviral drugs to treat SARS-CoV-2 infection. In this study we present systematic and integrative antiviral drug repurposing effort aimed at identifying, among the drugs already authorized for clinical use, some active inhibitors of the SARS-CoV-2 main protease. The most important result of this analysis is the demonstration that ethacrynic acid, a powerful diuretic, is revealed to be an effective inhibitor of SARS-CoV-2 main protease. Even with all the necessary cautions, given the particular nature of this drug, these data can be the starting point for the development of an effective therapeutic strategy against SARS-CoV-2.

Biofilm Matrix

The choice of an effective therapeutic strategy in the treatment of biofilm-related infections is a significant issue. Amyloids, which have been historically related to human diseases, are now considered to be prevailing structural components of the biofilm matrix in a wide range of bacteria. This assumption creates the potential for an exciting research area, in which functional amyloids are considered to be attractive targets for drug development to dissemble biofilm structures. The present review describes the best-characterized bacterial functional amyloids and focuses on anti-biofilm agents that target intrinsic and facultative amyloids. This study provides a better understanding of the different modes of actions of the anti-amyloid molecules to inhibit biofilm formation. This information can be further exploited to improve the therapeutic strategies to combat biofilm-related infections.

Psoriasis affects the health of myriad populations around the world. The pathogenesis is multifactorial, and the exact driving factor remains unclear. This condition arises from the interaction between hyperproliferative keratinocytes and infiltrating immune cells, with poor prognosis and high recurrence. Better clinical treatments remain to be explored. There is much evidence that alterations in the skin and intestinal microbiome play an important role in the pathogenesis of psoriasis, and restoration of the microbiome is a promising preventive and therapeutic strategy for psoriasis. Herein, we have reviewed recent studies on the psoriasis-related microbiome in an attempt to confidently identify the “core” microbiome of psoriasis patients, understand the role of microbiome in the pathogenesis of psoriasis, and explore new therapeutic strategies for psoriasis through microbial intervention.

The high transmissibility and replication of SARS-CoV-2 have been attributed to enhanced protein functions which are dependent on protein folding. Our in silico study endeavored to scrutinize SARS-CoV-2 ORF1ab by analyzing the conserved folding patterns of its transcribed proteins. Accordingly, the findings indicated that SARS-CoV-2 ORF1ab shares domain-specific fold-fingerprints with a spectrum of unrelated organisms. Closer observation revealed slight changes in folding patterns engendered with small variation in the intrinsic amino acid sequence. By correlating with the evolvability-potential of RNA-viruses and COVID-19 pandemic, we hypothesize that SARS-CoV-2 could undergo fast recombination with the host, SARS-CoV-2 minor variants and other viral species resulting in a reservoir of SARS-CoV-2 quasispecies. It is highly possible that natural selection will cause a future emergence of evolved SARS-CoV-2-descendants. Nonetheless, we hope that this insightful study will assist in elucidating SARS-CoV-2 protein functionalities, development of vaccines, and the possibility and nature of future emergence.

Effective Therapeutic Strategy

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was first identified in December 2019 in Wuhan, China, and has resulted in global pandemic. There is currently no effective therapeutic strategy for the management of mechanical ventilation or antiviral drugs for the treatment of this disease. As such, the development of a therapeutic strategy is urgently needed and should be established as soon as possible. In this case series, a therapeutic strategy was initially developed based on previous treatment methods used for the treatment of SARS and MERS in the absence of treatment options for COVID-19 due to a lack of information. During the search for a potential treatment, clinical findings were obtained from patients with severe COVID-19, and one therapeutic strategy was established. This therapeutic strategy was then applied to severe COVID-19 patients. In addition, we can require some interesting clinical features and characteristics of COVID-19 from blood analysis and physical findings. Here, we reported on the clinical features and characteristics of a therapeutic strategy for the treatment of severe COVID-19 pneumonia at our institution.

Insight Into

Pulmonary fibrosis (PF), a progressive and life-threatening pulmonary disease, is the main pathological basis of interstitial lung disease (ILD) which includes the idiopathic pulmonary fibrosis (IPF). No effective therapeutic strategy for pulmonary fibrosis has been established. TGF-β signaling has emerged as the vital regulator of PF; however, the detailed molecular mechanisms of TGF-β in PF were uncertain. In the present study, we proved that inhibition of MTORC2 suppresses the expression of P27 in MRC5 and HLF cells. And in bleomycin-induced PF model, the expression of α-SMA and P27 was upregulated. Moreover, TGF-β application increased the level of α-SMA, vimentin, and P27 in MRC5 and HLF cells. Furthermore, P27 overexpression advanced the cell cycle process and promoted the proliferation of MRC5 and HLF cells. Finally, the rescue experiment showed that MTORC2 knockdown reversed P27 overexpression-induced cell cycle acceleration and proliferation. Thus, our results suggest that P27 is involved in TGF-β-mediated PF, which was regulated by MTORC2, providing a novel insight into the development of PF.

Background: Malignant pheochromocytoma (mPCC) is an uncommon tumor with poor prognosis, and no effective therapeutic strategy exists as yet. Discovering new and effective therapeutic strategies to improve prognosis is an urgent need. Objective: To investigate whether a combinatorial inhibition of both mTORC2 and Hsp90 in PC12 cells could lead to a distinct anti-tumor effect in vitro and in vivo that was greater than the inhibition of mTORC2 or Hsp90 alone. Methods: Targeting mTORC2 was assessed by knockdown of Rictor using shRNA, and 17-AAG was used to inhibit Hsp90 function. Results: Combinatorial inhibition of both mTORC2 and Hsp90 could lead to a distinct anti-tumor effect in vitro that was greater than the inhibition of mTORC2 or Hsp90 alone. Inhibiting Hsp90 specifically could inhibit tumor growth of sh-Rictor cells in vivo, suggesting that the combinatorial inhibition of both mTORC2 and Hsp90 could lead to a distinct anti-tumor effect in vivo. Western blotting has shown that both p-Akt Ser473 and p-Akt Thr450 showed significantly decreased expression after targeting mTORC2, while p-Akt Thr308 did not. However, all three different p-AKTs, including p-Akt Ser473, p-Akt Thr450 and p-Akt Thr308, showed a significantly decreased expression in combinatorial inhibition of both mTORC2 and Hsp90. Collectively, it revealed that combinatorial inhibition of mTORC2 and Hsp90 could destabilize the Akt signaling. Conclusion: Our results demonstrated that combinatorial inhibition of mTORC2 and Hsp90 could increase their anti-tumor effect and destabilize the Akt signaling in PC12 cells, suggesting a combinatorial inhibition of both mTORC2 and Hsp90 which might be an effective therapeutic strategy for mPCC.

Insight Into

Both apoptosis and autophagy are highly conserved processes that besides their role in the maintenance of the organismal and cellular homeostasis serve as a main target of tumor therapeutics. Although their important roles in the modulation of tumor therapeutic strategies have been widely reported, the molecular actions of both apoptosis and autophagy are counteracted by cancer protective mechanisms. While apoptosis is a tightly regulated process that is implicated in the removal of damaged or unwanted cells, autophagy is a cellular catabolic pathway that is involved in lysosomal degradation and recycling of proteins and organelles, and thereby is considered an important survival/protective mechanism for cancer cells in response to metabolic stress or chemotherapy. Although the relationship between autophagy and cell death is very complicated and has not been characterized in detail, the molecular mechanisms that control this relationship are considered to be a relevant target for the development of a therapeutic strategy for tumor treatment. In this review, we focus on the molecular mechanisms of apoptosis, autophagy, and those of the crosstalk between apoptosis and autophagy in order to provide insight into the molecular mechanisms that may be essential for the balance between cell survival and death as well as their role as targets for the development of novel therapeutic approaches.
