Abstract

Insights

Autophagy genes PIK3C3 and RAB7A expression were significantly reduced in COVID-19 patients. Lower expression of these autophagy markers may aid in monitoring disease progression.

Area of Science:

  • Molecular Biology
  • Immunology
  • Virology

Background:

  • Autophagy's role in coronavirus infection and replication is debated.
  • Autophagy is a cellular process involving lysosomal breakdown and recycling of intracellular components.
  • Investigating autophagy gene expression in COVID-19 is crucial for understanding disease mechanisms.

Purpose of the Study:

  • To evaluate the expression of autophagy genes PIK3C3 and RAB7A in COVID-19 patients.
  • To determine if PIK3C3 and RAB7A can serve as biomarkers for monitoring COVID-19 patients.

Main Methods:

  • A case-control study involving 50 COVID-19 patients and 50 healthy controls.
  • Quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure gene expression levels.

Main Results:

  • PIK3C3 and RAB7A gene expression were significantly lower in COVID-19 patients compared to controls (p < 0.001).
  • PIK3C3 and RAB7A showed high sensitivity and specificity as potential biomarkers.
  • Gene expression correlated positively with inflammatory markers (WBCs, IL-6, CRP) and clinical indicators (neutrophils, D-dimer, ALT).

Conclusions:

  • COVID-19 patients exhibit reduced expression of PIK3C3 and RAB7A.
  • Further research is recommended to elucidate the specific roles of these autophagy genes in COVID-19 pathogenesis.

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Autophagy01:27

Autophagy

Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
