Resumen
Las nanopartículas de polímero molecularmente impresas identificaron distintas proteínas de la superficie de células de cáncer de pulmón. Este descubrimiento ofrece nuevos objetivos diagnósticos y terapéuticos para el desarrollo de fármacos contra el cáncer de pulmón.
Área de la Ciencia:
- Bioquímica
- Proteómica
- Nanotecnología
Sus antecedentes:
- La identificación de proteínas de la superficie celular es crucial para el desarrollo de fármacos contra el cáncer de pulmón.
- Las nanopartículas de polímero molecularmente impresas (nanoMIPs) proporcionan un método sintético para el reconocimiento de proteínas de la superficie celular.
Objetivo del estudio:
- Utilizar un novedoso método de 'impresión instantánea' para analizar proteomas de la superficie de células de cáncer de pulmón.
- Identificar posibles dianas de proteínas diagnósticas y terapéuticas para el cáncer de pulmón.

01:22Imprinting
11.1K
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

02:30Genomic Imprinting and Inheritance
37.1K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

01:01Polymers: Defining Molecular Weight
3.8K
Unlike small molecules with definite molecular weights, polymers are a mixture of individual polymer chains of varying lengths, each with a unique molecular weight. So, the molecular weight of a polymer is expressed as an average value based on the average size of the polymer chains. The two most common forms of averages used for polymers are the number average molecular weight and weight average molecular weight.

01:10Polymers: Molecular Weight Distribution
4.8K
For any given polymer, the weight average molecular weight (Mw) is higher than, if not equal to, the number average molecular weight (Mn). The only situation in which the weight average molecular weight and the number average molecular weight are equal is when a polymer consists only of chains with equal molecular weight. However, this never happens in a synthetic polymer, since it is difficult to control the polymerization process up to a molecular level with accuracy to a hundred percent.

01:08Molecular Weight of Step-Growth Polymers
2.8K
Step growth polymerization involves bi or multifunctional monomers. Bifunctional monomers react to form linear step growth polymers, whereas multifunctional monomers react to form non-linear or branched polymers.
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...
