HSET is overexpressed in triple-negative breast cancer, which is associated ... Set Symbols. A set is a collection of things, usually numbers. We can list each element (or "member") of a set inside curly brackets like this: Common Symbols Used in Set TheoryHere, we report the discovery of a novel 2-(3-benzamidopropanamido)thiazole-5-carboxylate with micromolar in vitro inhibition of HSET (KIFC1) through high-throughput screening and its progression to ATP-competitive compounds with nanomolar biochemical potency and high selectivity against the opposing mitotic kinesin Eg5.

To monitor GFP-HSET turnover on mitotic spindle microtubules upon IFT88 depletion, GFP-HSET was introduced in an isogenic manner in the DLD-1 IFT88-AID cell line, described in Fig 1.HSET has a role in controlling spindle length by cross-linking and sliding microtubules. High KIFC1 expression is associated with metastatic spread to the brain in primary non-small cell lung cancer. An analysis was made of the weak interactions of ADP-Unc104 and ADP-kinesin with microtubules and their inhibition by MAP2.Redis hash 命令. 查看哈希表 key 中，指定的字段是否存在。. 获取存储在哈希表中指定字段的值。. 为哈希表 key 中的指定字段的整数值加上增量 increment 。. 为哈希表 key 中的指定字段的浮点数值加上增量 increment 。. 同时将多个 field-value (域-值)对设置到哈希表 key 中 ... in node.js, if you already have the key / value in an object, you can do this. await redis.hset ('myhashset', { field1: value1, field2: value2 }) i figure out that my problem was with my redis client. my redise version is 5 but my redis client doesn't support new features in Redis 5. so i use ioredis and this redis client support hmset now ...Microtubule sliding driven by kinesin-14 HSET is regulated by a feedback mechanism. When microtubules start sliding apart, HSET molecules are retained in the shortening overlap, which leads to an ...Here again, we’ll use the hset command to add a new field-value pair. So the command we’ll run is hset player:42 status dazed. What happens when our player no longer has the status of “dazed”? We’ll want to remove the status field from the hash instance. To delete a field-value pair from a Redis hash, we use the command hdel.
