Summary
Clear cell renal cell carcinoma (ccRCC) shows proteometabolomic reprogramming. Protein moonlighting and biomarker localization offer new therapeutic targets for this challenging kidney cancer.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Clear cell renal cell carcinoma (ccRCC) remains difficult to treat with chemotherapy.
- Recent proteomic and metabolomic studies reveal a grade-defined reprogramming model in ccRCC.
- This model identifies potential therapeutic targets, many regulated by the MYC transcription factor.
Purpose of the Study:
- To explore novel therapeutic strategies for ccRCC.
- To investigate the role of protein moonlighting in ccRCC.
- To understand the significance of subcellular localization of biomarkers in ccRCC progression.
Main Methods:
- Proteomic and metabolomic analyses in a grade-defined manner.
- Characterization of transcription factor control, including MYC.
- Application of immunohistochemistry to study protein moonlighting and biomarker localization.
Main Results:
- A global proteometabolomic reprogramming model for ccRCC was established.
- MYC proto-oncogene, bHLH transcription factor, was identified as a key regulator.
- Protein moonlighting was recognized as a factor in ccRCC metabolic reprogramming.
- Subcellular localization of biomarkers emerged as a critical molecular signature.
Conclusions:
- The proteometabolomic reprogramming model provides new drug targets for ccRCC.
- Protein moonlighting and biomarker subcellular localization represent novel aspects of ccRCC pathology.
- Further research into the functional significance of these findings is warranted for ccRCC treatment.

02:33Lattice Centering and Coordination Number
11.2K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

02:54Classification of Elements and Compounds
72.4K
Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond. Elements are classified as atomic or molecular based on the nature of their basic units.
Compounds are pure substances composed of two or more elements in fixed, definite proportions. Compounds are classified as ionic or molecular (covalent) based on the bonds...

02:37Metallic Solids
20.3K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.

01:29Aggregates Classification
904
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...

01:21Aggregate Cement Ratio
484
The Aggregate Cement ratio refers to the weight of aggregate divided by the weight of cement in a concrete mix. Altering this ratio has profound effects on the concrete's properties. This ratio plays a pivotal role in determining the strength, workability, and durability of concrete. When the Aggregate Cement ratio is higher, the mix is leaner, meaning it has less cement paste to lubricate the aggregate, potentially making the concrete less workable. Such mixes, known as lean, enhance the...
