Abstract

Insights

Circular RNA SLC8A1 (circ-SLC8A1) is reduced in osteoporosis and counteracts miR-516b-5p's effects on AKAP2. This finding offers a potential new treatment strategy for osteoporosis.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • Osteoporosis is a bone disease marked by bone loss and altered bone metabolism.
  • Circular RNAs (circRNAs) are emerging regulators in human diseases, but their role in osteoporosis is not well understood.

Purpose of the Study:

  • To investigate the expression and mechanism of circRNAs in osteoporosis.
  • To explore the role of circ-SLC8A1 in the context of osteoporosis.

Main Methods:

  • Bioinformatic prediction of microRNA binding sites.
  • Dual luciferase assays to confirm target interactions.
  • Quantitative reverse transcriptase-polymerase chain reaction to assess gene expression.
  • Cell staining assays to evaluate osteogenic differentiation.

Main Results:

  • Circ-SLC8A1 expression was significantly decreased in an osteoporosis mouse model.
  • Circ-SLC8A1 negatively regulated miR-516b-5p expression.
  • Overexpression of circ-SLC8A1 inhibited miR-516b-5p's suppressive effect on AKAP2.

Conclusions:

  • Circ-SLC8A1 inhibits miR-516b-5p's action on AKAP2, thereby influencing osteoporosis.
  • Circ-SLC8A1 presents a potential therapeutic target for osteoporosis treatment.

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Bone Remodeling01:40

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

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...
